Abstract

The invention provides a scene change sensing method, which comprises the following steps of: step 1, initializing a message queue, and setting an original picture; step 2, capturing a video picture according to a preset time period; setp 3, clipping the intercepted video picture, and comparing the clipped video picture with the original picture for analysis; step 4, if finding that the picture isthe same as the original picture, feeding back to the system without any processing; if not, storing the clipped video picture into a memory, and continuing to execute the step 5; step 5, after waiting for a preset time period, intercepting the video picture again; step 6, clipping the video picture obtained in the step 5, and comparing the clipped video picture with the video picture stored in the memory for analysis; step 7, if finding that the video picture is the same as the video picture stored in the memory, feeding back to the system to execute returning to the preset position; and ifnot, storing the cut video picture in the step 6 into a memory, replacing the originally stored video picture, and continuing to execute the step 5.

Description

technical field [0001] The invention relates to a video image analysis method, in particular to a scene change perception method. Background technique [0002] With the continuous update of security industry standards and the implementation of AI algorithms, artificial intelligence, etc. Automation and intelligence have become the trend of security and related industries. The update of security, automation, and intelligence promotes the continuous improvement of the country's requirements for compatibility and intelligence between security industry platforms. With the continuous expansion of the scope of intelligent security, the application of video analysis algorithms has become the development direction of the security industry. [0003] At present, only the comparison of pictures has been done in this field, and it has not been actually used in the scene. The scene change perception method proposed by the present invention can effectively judge whether the scene monit...
