, Description:FIELD OF INVENTION
[0001] Embodiments of a present disclosure relate to entity monitoring and locating, and more particularly to a system and method to monitor and locate an entity in an indoor environment.
BACKGROUND
[0002] Typical monitor and location finding systems will use GPS (Global Positioning System) technology to find location details for an outdoor environment. At the same time, when it comes to indoor environments the GPS technology is inadequate, and typically signals from the satellites are not accurate enough to monitor and locate the plurality of entities. Monitoring and localization of a plurality of entities in an indoor environment is an important process for industries, particularly for large-scale manufacturing industry. The indoor environment may also include a shopping mall, museum, amusement park, and the like. The indoor environment monitoring and locating system can be used to locate the plurality of entities inside buildings, typically via a computing device. Monitoring and locating services keep a user informed of changes in a position of the plurality of entities.
[0003] The conventional system may use combination of sensors (E,g., gyroscope sensor and accelerometer sensor) to monitor an activity of the plurality of entities, but the sensors (E.g., the gyroscopes sensor and the accelerometer sensor) fails to produce high accuracy results when there is any drift in position of the gyroscopes and the accelerometers. The magnetic sensors may provide high accuracy results when there is no magnetic interference in the indoor environment. If there is any magnetic interference in the indoor environment, the magnetic sensor fails to provide high accuracy results.
[0004] A newer system may use image capturing devices to monitor and locate the plurality of entities which leads to a manual process. The manual process makes the system slow, and the manual process will not allow the newer system to run as real time. Due to the manual monitoring and locating process, the newer system may be expensive for the manufacturing industry because the newer system needs to hire people for the manual monitoring and locating process.
[0005] Hence, there is a need for an improved system and method to monitor and locate an entity in an indoor environment to address the aforementioned issues.

[0049] The method (280) also includes identifying an activity of the entity in the indoor environment in step 360. In one embodiment, identifying the activity of the entity includes identifying the activity of the entity in the indoor environment by an image capturing module. In one embodiment, the image capturing devices may include, but not limited to, a camera. In such embodiment, the camera is configured to at least one of one or more images and one or more videos. In one embodiment, the activity of the entity may include a movement of the entity (20) such as walking, running, jogging, and the like in case of the entity being the human. In another embodiment, the movement of the entity may include a speed of the object, direction of movement of the object, path of movement of the object and the like. In one embodiment, the plurality of image capturing devices is placed in the indoor environment in a predetermined manner.
[0050] The method (280) also includes merging the identified location of the entity with an identified activity of the entity by object detection and identification techniques in step 370. In one embodiment, merging the identified location of the entity includes merging the identified location of the entity with the identified activity of the entity by object detection and identification techniques by a data merging module. The method (280) also includes monitoring the activity of the entity in real time in step 380. In one embodiment, monitoring the activity of the entity includes monitoring the activity of the entity in real time by a monitoring module.
[0051] In some embodiments, the method (280) also includes placing the plurality of image capturing devices in the indoor environment in a predetermined manner. In some embodiments, the method (280) also includes generating a plurality of notifications to guide a user to guide the entity. In one embodiment, the plurality of notifications may include, but not limited to, a text notification, a push notification, and a multimedia notification. In such embodiment, the user may receive the notification via a computing device. In such embodiment, the computing device may be a hand-held device. In one embodiment, the computing device may include, but not limited to, a laptop, a desktop, a notebook, a tablet, a smartphone and the like. In such another embodiment, the computing device may be a portable device.
[0052] In exemplary embodiment, the method (280) includes the at least four ultra-wideband generators to set up a network to monitor the entity in the indoor environment. The method (280) also includes at least three ultra-wideband generators to locate and monitor the entity in the indoor environment.
[0053] Various embodiments of the present disclosure enable the system to increase accuracy the identified distance by comparing the identified distance with the predetermined distance. The present disclosure increases the speed of the system by identifying the activity of the entity by the image capturing module automatically. In addition to that the present disclosure merges the identified location of the entity (sensor data) with an identified activity of the entity (a computer vision) by object detection and identification techniques to obtain better accuracy.
[0054] While specific language has been used to describe the disclosure, any limitations arising on account of the same are not intended. As would be apparent to a person skilled in the art, various working modifications may be made to the method in order to implement the inventive concept as taught herein.
[0055] The figures and the foregoing description give examples of embodiments. Those skilled in the art will appreciate that one or more of the described elements may well be combined into a single functional element. Alternatively, certain elements may be split into multiple functional elements. Elements from one embodiment may be added to another embodiment. For example, order of processes described herein may be changed and are not limited to the manner described herein. Moreover, the actions of any flow diagram need not be implemented in the order shown; nor do all of the acts need to be necessarily performed. Also, those acts that are not dependant on other acts may be performed in parallel with the other acts. The scope of embodiments is by no means limited by these specific examples.
