Abstract

The present disclosure relates to systems, methods, and apparatuses for correcting a camera configuration used in fixed-position surveillance. A video stream generated by the surveillance camera is obtained. A pattern present in pixel data of a frame of the video stream is analyzed to derive an initial orientation setting of the surveillance camera. An orientation delta between the initial orientation setting of the surveillance camera and a desired orientation setting for the surveillance camera is determined based on the analyzing of the pattern present in the pixel data of the frame. A configuration change for the surveillance camera is generated. The configuration change is provided to the surveillance camera to cause the surveillance camera to update the initial orientation setting of the surveillance camera.

First claim

The invention claimed is:

1 . A method for correcting a camera configuration for a surveillance camera having a fixed position, comprising:
obtaining a video stream generated by the surveillance camera, the video stream comprising a plurality of frames; analyzing a pattern present in pixel data of a frame of the video stream to derive an initial orientation setting of the surveillance camera; determining an orientation delta between the initial orientation setting of the surveillance camera and a desired orientation setting for the surveillance camera based on the analyzing of the pattern present in the pixel data of the frame; generating a configuration change for the surveillance camera; and providing the configuration change to the surveillance camera to cause the surveillance camera to update the initial orientation setting of the surveillance camera.

2 . The method of claim 1 , comprising obtaining, subsequent to providing the configuration change to the surveillance camera, additional frames of the video stream having a different orientation than an orientation of the frame of the video stream.

3 . The method of claim 1 , wherein analyzing the pattern present in the pixel data of the frame comprises performing object detection to determine that an orientation of an object differs vis-à-vis an expected orientation for the object.

4 . The method of claim 1 , wherein performing object detection comprises detecting a person.

5 . The method of claim 1 , wherein performing object detection comprises detecting a landmark.

6 . The method of claim 1 , wherein generating the configuration change comprises generating a configuration change specifying a rotation for future frames of the video stream.

7 . The method of claim 1 , wherein generating the configuration change comprises generating a configuration change specifying a reflection for future frames of the video stream.

8 . The method of claim 1 , comprising, responsive to the determining of the orientation delta, issuing an alert to an operator of a surveillance system associated with the surveillance camera.

9 . The method of claim 8 , comprising obtaining input from the operator approving the configuration change, wherein the providing of the configuration change occurs responsive to the obtaining of the input from the operator.

10 . The method of claim 8 , wherein issuing the alert to the operator comprises presenting a confidence level associated with the determining that the orientation of the object differs vis-à-vis the expected orientation.

11 . The method of claim 8 , wherein issuing the alert to the operator comprises presenting a plurality of potential corrections for the surveillance camera to be included in the configuration change.

12 . The method of claim 8 , wherein issuing the alert to the operator comprises presenting an indication of a potential installation issue associated with the surveillance camera.

13 . The method of claim 1 , comprising comparing a confidence level associated with the initial orientation setting with a confidence threshold, wherein, when the confidence level does not meet the confidence threshold, issuing an alert to the operator indicating a potential issue with the surveillance camera.

14 . The method of claim 1 , wherein the method forms part of a surveillance camera enrollment method comprising
obtaining a request to enroll the surveillance camera; and responsive to obtaining the request, enrolling the surveillance camera, wherein the obtaining of the video stream occurs subsequent to the enrolling of the surveillance camera.

15 . The method of claim 14 , wherein the request to enroll comprises an orientation validation request for the surveillance camera.

16 . The method of claim 1 , wherein the obtaining, analyzing, determining, generating, and providing are performed subsequent to identifying an occurrence of an event in a vicinity of the surveillance camera.

17 . The method of claim 16 , wherein identifying the occurrence of the event comprises identifying: a weather event; a maintenance event; and/or an emergency event.

18 . The method of claim 1 , comprising receiving an orientation validation request from the surveillance camera, wherein the obtaining, detecting, analyzing, generating, and providing are performed in response to receiving the orientation validation request.

19 . The method of claim 1 , wherein the obtaining, analyzing, determining, generating, and providing are repeated periodically.

20 . The method of claim 1 , wherein obtaining the video stream comprises obtaining, at a video management system, the video stream from the surveillance camera, and wherein providing the configuration change to the surveillance camera comprises transmitting, from the video management system, the configuration change to the surveillance camera over a network.

21 . The method of claim 1 , wherein the method is implemented within the surveillance camera.

22 . A surveillance camera for use in fixed-position surveillance, comprising:
an imaging unit; a network interface; a processor in communication with the imaging unit and the network interface; and a non-transitory computer-readable memory storing computer instructions executable by the processor for:
obtaining a video stream generated by the surveillance camera, the video stream comprising a plurality of frames;
analyzing a pattern present in pixel data of a frame of the video stream to derive an initial orientation setting of the surveillance camera;
determining an orientation delta between the initial orientation setting of the surveillance camera and a desired orientation setting for the surveillance camera based on the analyzing of the pattern present in the pixel data of the frame;
generating a configuration change for the surveillance camera; and
providing the configuration change to the surveillance camera to cause the surveillance camera to update the initial orientation setting of the surveillance camera.

23 . A surveillance system for use in fixed-position surveillance, comprising:
a server implementing a video management system, the server in communication with a surveillance camera over a surveillance network; wherein the server comprises:
a processor; and
a non-transitory computer-readable memory storing computer instructions executable by the processor for:
obtaining a video stream generated by the surveillance camera, the video stream comprising a plurality of frames;
analyzing a pattern present in pixel data of a frame of the video stream to derive an initial orientation setting of the surveillance camera;
determining an orientation delta between the initial orientation setting of the surveillance camera and a desired orientation setting for the surveillance camera based on the analyzing of the pattern present in the pixel data of the frame;
generating a configuration change for the surveillance camera; and
providing the configuration change to the surveillance camera to cause the surveillance camera to update the initial orientation setting of the surveillance camera.

24 . The system of claim 23 , wherein the computer instructions are executable by the processor for obtaining, subsequent to providing the configuration change to the surveillance camera, additional frames of the video stream having a different orientation than an orientation of the frame of the video stream.
