DETAILED DESCRIPTION OF THE INVENTION
[0015] Figure 1 illustrates a system 100 for configuring at least one camera of a surveillance unit over a communications network, according to an embodiment of the present invention. The system 100 includes a remote device 110, a camera management unit (CMU) 130 and a surveillance unit 150 having at least one camera.
[0016] The remote device 110 includes an interface 112 having a plurality of survey attributes, an image capturing unit 114, a memory bank 116, a mapping engine 118, a second syncing component 120 operable on a processor 122 and a transmitter 124.
[0017] The CMU 130 includes a transceiver 132, a first syncing component 134, a processing unit 136, a database 138 and a configuration unit 140 including a validation unit 142.
[0018] In accordance with an embodiment of the invention, within the remote device 110, the interface 112 is in communication with the mapping engine 118. The image capturing unit 114, the mapping engine 118, the second syncing component 120 and the transmitter 124 are in communication with the memory bank 116.
[0019] Within the CMU 130, the first syncing component 134 is in communication with the transceiver 132. The transceiver 132 is in communication with the processing unit 136. The processing unit 136 is in communication with the configuration unit 140 including a validation unit 142. Further, the first syncing component 134, the transceiver 132, the processing unit 136 and the configuration unit 140 are in communication with the database 138.
[0020] With reference to figure 1 of an embodiment of the invention, the system 100 configures the at least one camera of the surveillance unit 150 over a communications network. The surveillance unit 150 is installed in a specified region, hereinafter referred to as the region.
[0021] The interface 112 of the remote device 110 displays a plurality of survey attributes to a user. The plurality of attributes include field of view of the at least one camera, camera type required at the region, camera location in the region, power requirements, type of network connectivity, camera configuration details, GPS location of the camera, etc. Based upon the plurality of survey attributes displayed at the remote device 110, if the user selects at least one survey attribute such as field of view of the camera, the user will capture a reference frame using an image capturing unit 114 of the remote device. The reference frame is indicative of the at least one survey data value. The captured reference frame is stored at the memory bank 116 of the remote device 110. The reference frame will include information such as GPS location of the captured reference frame and time when the reference frame was captured, etc.
[0022] With reference to figure 1 of the present invention, the mapping engine 118 of the remote device 110, assigns at least one unique identifier to the at least survey data value input from the user. The mapping engine 118 assigns the unique identifier to the survey data value, in response to receiving the survey data value from the user. The survey data value is stored in the memory bank 116 of the remote device 110. With regard to the reference frame as mentioned above, the mapping engine 118 assigns a particular unique identifier to the reference frame. The unique identifier will include information such as the GPS location of the reference frame and time when the frame was captured.
[0023] Once, the unique identifier is assigned to the survey data value, a first syncing component 134 of the CMU 130, establishes a communication link with the remote device 110. In accordance with an embodiment of the invention, the first syncing component 134 of the CMU 130 communicates with the second syncing component 120 of the remote device for establishing a communication link. During the communication link establishment step, the first syncing component 134 determines the address of the remote device 110 via the second syncing component 120.
[0024] In an alternate embodiment of the invention, the second syncing component 120 of the remote device 110 establishes the communication link with the CMU 130, once the unique identifier is assigned to the survey data value.
[0025] The transceiver 132 of the CMU 130 receives the survey data value along with the unique identifier from the transmitter 124 of the remote device 110 and stores it at the database 138 of the CMU 130.
[0026] In accordance with an embodiment of the invention, the processing unit 136 of the CMU 130, identifies at least one camera data value from the plurality of camera data values having one or more camera attributes similar to the survey data value. The processing unit 136, correlates the one or more camera attributes of the at least one camera data value with the unique identifier of the survey data value in identifying the at least one camera data value. For instance, the survey data value being a reference frame, the reference frame of an ‘X’ region is captured at 6 AM in the morning by the remote device 110. A unique identifier is assigned to the reference frame. The processing unit 136 of the CMU will correlate each of the plurality of camera data values with the reference frame, and extract at least one camera data value having one or more attributes similar to the reference frame. For instance, the camera installed at the surveillance unit 150 transmits a plurality of camera frames, i.e. the plurality of camera data values, captured in an entire day to the CMU 130. The processing unit 136 extracts the camera frame which was captured at 6 AM in the morning for the same region ‘X’, by correlating with the unique identifier of the reference frame.
[0027] In accordance with an embodiment of the invention, the validation unit 142 of the configuration unit 140 compares the survey data value, herein the reference frame with the camera data value, herein the camera frame identified by the processing unit 136. Based upon the result of comparison of the camera frame with the reference frame, the validation unit 142 determines validity of the camera frame. For instance, the validation unit generates the result as a percentage value of comparison of the camera frame with the reference frame. If the camera frame varies compared by a certain percentage value compared to the reference frame, the validation unit generates an alarm indicating that the field of view of the camera is disoriented. Based on the alarm generated by the validation unit 142, the configuration unit 140 configures the field of view of the camera based on the survey data value (reference frame).
[0028] In accordance with an embodiment of the invention, during comparison of the survey data value with the camera data value by the validation unit 142, an acceptable percentage variation value is pre-configured at the validation unit. The pre-configured acceptable percentage variation value is not limited to percentages; it can be any pre-configured range of values, threshold, etc. For instance, if the acceptable percentage variation value is pre-configured at 20 percent, then if the camera frame varies by 25 percent compared to the reference frame, an alarm is generated indicating that the field of view of the camera is disoriented. Whereas, if the camera frame varies by only 10 percent compared to the reference frame, then the field of view of the camera will be termed as oriented. Hence, the field of view of the camera is not required to be configured. The validation unit 142, determines percentage variation of the camera frame with the reference frame by superimposing the camera frame on the reference frame and identifying the variation of the camera frame.
[0029] In yet another embodiment of the invention, the survey data value, herein the reference frame may have one or more permanent objects such as poles, trees, etc. In such conditions, the processor 122 of the remote device marks the one or more permanent objects of the reference frame. Therefore, during comparison of the reference frame with the camera frame, if there is any variation in the field of view of the camera frame, the validation unit 142 generates an alarm.
[0030] In yet another embodiment of the invention, the reference frame captured may have one or more temporary objects such as a car passing by, due to which the accuracy of configuration of the camera may vary depending on the percentage of the temporary objects present in the reference frame (the survey data value). During the above mentioned condition, the processor 122 will remove the one or more temporary objects. In conditions, wherein the one or more temporary objects cannot be removed from the reference frame, then the acceptable percentage variation value which is pre-configured at the validation unit 142 of the CMU 130 is set high. For instance, the acceptable percentage variation may be set at 15 percent instead of 20 percent, if the one or more temporary objects cannot be removed from the reference frame. Therefore, there will be two sets of acceptable percentage variation values pre-configured at the processor 122. During the presence of temporary objects in the reference frame, the processor 122 will set the acceptable percentage variation value to a specific value, and when there are no temporary objects in the reference frame, the acceptable percentage variation value will be set to a another specific value as mentioned in the above example.
[0031] In accordance with an embodiment of the invention, the at least one camera installed at the surveillance unit may be a CCTV camera or an internet protocol camera.
[0032] In accordance with an embodiment of the invention, the remote device, the CMU and the surveillance unit of system 100 communicate with each other over a communications network such as local area network (LAN), Metropolitan Area Network (MAN), Wide Area Network (WAN), Wireless Network and Inter Network, etc.
[0033] Figure 2 illustrates a remote device 200. The remote device includes an interface 202 having a plurality of survey attributes, an image capturing unit 204, a memory bank 206, a mapping engine 208, a second syncing component 210 operable on a processor 212 and a transmitter 214.
[0034] In accordance with an embodiment of the invention, within the remote device 200, the interface 202 is in communication with the mapping engine 206. The image capturing unit 204, the mapping engine 206, the second syncing component 210 and the transmitter 214 are in communication with the memory bank 208.
[0035] The interface 202 of the remote device 200 displays a plurality of survey attributes to a user. The plurality of attributes include field of view of the at least one camera, camera type required at the region, camera location in the region, power requirements, type of network connectivity, camera configuration details, GPS location of the camera, etc. Based upon the plurality of survey attributes displayed at the remote device 200, if the user selects at least one survey attribute such as field of view of the camera, the user will capture a reference frame using an image capturing unit 204 of the remote device 200. The reference frame is indicative of the at least one survey data value. The captured reference frame is stored at the memory bank 208 of the remote device 200. The reference frame will include information such as GPS location of the captured reference frame, time when the reference frame was captured, etc.
[0036] With reference to figure 2 of the present invention, the mapping engine 206 of the remote device 200, assigns at least one unique identifier to the at least survey data value input from the user. The mapping engine 206 assigns the unique identifier to the survey data value, in response to receiving the survey data value from the user. The survey data value is stored in the memory bank 208 of the remote device 200. With regard to the reference frame as mentioned above, the mapping engine 206 assigns a particular unique identifier to the reference frame. The unique identifier will include information regarding the GPS location of the reference frame and time when the frame was captured.
[0037] In accordance with an embodiment of the invention, once, the unique identifier is assigned to the survey data value, the second syncing component 210 of the remote device 200, establishes a communication link with a camera management unit (CMU). The second syncing component 210 operates on a processor 212. The second syncing component 210, sends a request sync signal to the CMU. Based upon an acknowledgment sync signal received from the CMU, the processor 210 of the remote device 200 determines a data format compatible with the CMU. Based on the determination of the data format of the CMU, the processor 212 of the remote device 200, converts the survey data value to the determined data format.
[0038] The transmitter 214 of the remote device 200 transmits the survey data value along with the unique identifier in the converted data format to the CMU.
[0039] With reference to figure 3 of an embodiment of the invention, a flowchart of a method for configuring at least one camera of a surveillance unit over a communications network is illustrated. The method comprises the following steps:
[0040] At step 302, at least one survey data value is received at a remote device. The at least one survey data value is received, in response to at least one survey attribute selected by the user from a plurality of survey attributes available to the user on the remote device. The plurality of survey attributes include field of view of the at least one camera, camera type required at the region, camera location in the region, power requirements, type of network connectivity, camera configuration details, etc. The at least one survey data value includes information for future installation of the surveillance unit at the region.
[0041] At step 304, a mapping engine of the remote device, assigns at least one unique identifier to the at least one survey data value, in response to the at least one survey attribute selected by the user.
[0042] At step 306, a communication link is established between the remote device and a camera management unit (CMU). The CMU stores a plurality of camera data values received from the at least one camera installed at the surveillance unit of the at least one region. A first syncing component of the CMU establishes the communication link with a second syncing component of the remote device.
[0043] At step 308, the survey data value is transmitted along with the unique identifier from the remote device to the CMU.
[0044] At step 310, a processing unit of the CMU, identifies at least one camera data value from the plurality of camera data values having one or more camera attributes similar to the survey data value. The processing unit correlates the one or more camera attributes of the at least one camera data value with the unique identifier of the survey data value in identifying the at least one camera data value.
[0045] At step 312, a configuration unit of the CMU configures the at least one camera data value based on a result of comparison of the camera data value with the survey data value, thereby configuring the at least one camera. Before configuring the at least camera data value, a validation unit of the configuration unit validates the at least one camera data value based upon a result of comparison of the camera data value with the survey data value. During comparison of the survey data value with the camera data value by the validation unit, an acceptable percentage variation is pre-configured at the validation unit. For instance, if the acceptable percentage variation is pre-configured at 20 percent, then if the camera data value for instance a camera frame varies by 25 percent compared to the survey data value for instance a reference frame, then an alarm is generated indicating disoriented camera installed at the surveillance unit. Whereas, if the camera frame varies by only 10 percent compared to the reference frame, then the camera will be termed as oriented. Hence, the field of view of the camera is not required to be configured.
[0046] With reference to figure 4 of an embodiment of the invention, a flowchart of a method for validating at least one camera of a surveillance unit over a communications network is illustrated. The method comprises the following steps:
[0047] At step 402, at least one survey data value is received at a remote device. The at least one survey data value is received, in response to at least one survey attribute selected by the user from a plurality of survey attributes available to the user on the remote device. The plurality of survey attributes include field of view of the at least one camera, camera type required at the region, camera location in the region, power requirements, type of network connectivity, camera configuration details, etc. The at least one survey data value includes information for future installation of the surveillance unit at the region.
[0048] At step 404, a mapping engine of the remote device, assigns at least one unique identifier to the at least one survey data value, in response to the at least one survey attribute selected by the user.
[0049] At step 406, a communication link is established between the remote device and a camera management unit (CMU). The CMU stores a plurality of camera data values received from the at least one camera installed at the surveillance unit of the at least one region. A first syncing component of the CMU establishes the communication link with a second syncing component of the remote device. In another embodiment with respect to step 406, the second syncing component of the remote device establishes the communication link with the first syncing component of the CMU, once the at least one unique identifier is assigned to the at least one survey data value.
[0050] At step 408, a processing unit checks for presence of the at least one survey data value at the CMU. The processing unit of the CMU checks for presence of the survey data value based on address of the remote device received during the step 406 of establishing communication link between the CMU and remote device.
[0051] In the absence of the survey data value at the CMU, at least one request signal along with unique identifier and an acknowledgment signal are transmitted from the CMU to the remote device in response to receiving the request signal at step 410.
[0052] At step 412, a processing unit of the CMU, identifies at least one camera data value from the plurality of camera data values having one or more camera attributes similar to the survey data value. The processing unit correlates the one or more camera attributes of the at least one camera data value with the unique identifier of the survey data value in identifying the at least one camera data value.
[0053] At step 414, a validation unit of CMU validates the at least one camera data value based on a result of comparison of the camera data value with the survey data value, thereby validating the at least one camera.
[0054] The method of validating at least one camera as illustrated in figure 4 of the flowchart, can be used for future benchmark validation of any incremental installation of one or more cameras at the surveillance unit.
[0055] The foregoing description of the invention has been set merely to illustrate the invention and is not intended to be limiting. Since, modifications of the disclosed embodiments incorporating the spirit and substance of the invention may occur to person skilled in the art, the invention should be construed to include everything within the scope of appended claims.
