Claims:We claim:

1. A method for monitoring oxygen level, the method comprising:
receiving, by a monitoring device, at least one image of an environment comprising plurality of users, from a capturing device;
detecting, by the monitoring device, at least one region of interest of each of plurality of users in the at least one image;
generating, by the monitoring device, a video plethysmographic waveform by analyzing the at least one region of interest;
determining, by the monitoring device, peripheral capillary oxygen saturation (SPO2) level of each of the plurality of users based on the video plethysmograph waveform, wherein an average of the SPO2 level of each of the plurality of users corresponds to an oxygen level of the environment;
comparing, by the monitoring device, the oxygen level of the environment with a predefined oxygen level for the environment; and
performing, by the monitoring device, one or more actions based on the comparison for monitoring oxygen level of an environment.

2. The method as claimed in claim 1, wherein the region of interest comprises uncovered body parts of the user.

3. The method as claimed in claim 1, wherein the at least one image is divided into plurality of clusters, wherein each cluster of the plurality of clusters comprises a predefined number of users of the plurality of users.

4. The method as claimed in claim 3, further comprising averaging SPO2 of the predefined number of users to determine first average of SPO2 of each the plurality of clusters.

5. The method as claimed in claim 4 further comprising averaging the first average of SPO2 of each of the plurality of clusters to obtain an average SPO2.

6. The method as claimed in claim 1, wherein the one or more actions is at least one of, monitoring the oxygen level, storing the oxygen level for further analysis, providing a notification to a display unit and providing supply of oxygen to the environment.

7. A monitoring device for monitoring oxygen level, the device comprising:
a processor; and
a memory communicatively coupled to the processor, wherein the memory stores processor-executable instructions, which, on execution, causes the processor to:
receive at least one image of an environment comprising plurality of users, from a capturing device;
detect at least one region of interest of each of plurality of users in the at least one image;
generate a video plethysmographic waveform by analyzing the at least one region of interest;
determine peripheral capillary oxygen saturation (SPO2) level of each of the plurality of users based on the video plethysmograph waveform, wherein an average of the SPO2 level of each of the plurality of users corresponds to an oxygen level of the environment;
compare the oxygen level of the environment with a predefined oxygen level for the environment; and
perform one or more actions based on the comparison for monitoring oxygen level of an environment.

8. The monitoring device as claimed in claim 7, wherein the region of interest comprises uncovered body parts of the user.

9. The monitoring device as claimed in claim 7, wherein the at least one image is divided into plurality of clusters, wherein each cluster of the plurality of clusters comprises a predefined number of users of the plurality of users.

10. The monitoring device as claimed in claim 9, wherein the processor is further configured to average SPO2 of the predefined number of users to determine first average of SPO2 of each the plurality of clusters.

11. The oxygen monitoring system as claimed in claim 10, wherein the processor is further configured to average the first average of SPO2 of each of the plurality of clusters to obtain an average SPO2.

12. The oxygen monitoring system as claimed in claim 7, wherein the one or more actions is at least one of, monitoring the oxygen level, storing the oxygen level for further analysis, providing a notification to a display unit and providing supply of oxygen to the environment.

13. A non-transitory computer readable medium including instructions stored thereon that when processed by at least one processor cause a device to perform operations comprising:
receiving, at least one image of an environment comprising plurality of users, from a capturing device;
detecting at least one region of interest of each of plurality of users in the at least one image;
generating a video plethysmographic waveform by analyzing the at least one region of interest;
determining peripheral capillary oxygen saturation (SPO2) level of each of the plurality of users based on the video plethysmograph waveform, wherein an average SPO2 level is determined by averaging the SPO2 level of each of the plurality of users, wherein an average of the SPO2 level of each of the plurality of users corresponds to an oxygen level of the environment;
comparing the oxygen level of the environment with a predefined oxygen level for the environment; and
performing one or more actions based on the comparison for monitoring oxygen level of an environment.

14. The medium as claimed in claim 13, wherein the at least one image is divided into plurality of clusters by the processor, wherein each cluster of the plurality of clusters comprises predefined number of users.
