Object movement detection method, device, equipment and storage medium based on video images

Abstract

The invention discloses a video image-based object movement detection method, device, equipment and storage medium. The method includes: by obtaining the YUV pixel component value of each pixel point of the current frame image in the surveillance video, Perform similarity matching with the pre-established background pixel model corresponding to each pixel to obtain the similarity matching value of the corresponding pixel; match the obtained similarity matching value of each pixel of the current frame image with the preset matching Thresholds are compared to distinguish the pixels that are the background of the image and the pixels that are the foreground of the image in the current frame image; obtain the connected area formed by the adjacent pixels of the foreground of the image, and judge whether the area of ​​each connected area is is greater than the preset area threshold, so as to obtain the object motion detection result of the current frame image. The invention can solve the problem that the calculation efficiency of the motion detection is affected by the calculation resource occupied by the color space conversion process of the motion detection algorithm in the prior art.

Description

technical field [0001] The present invention relates to the field of video technology, in particular to a video image-based object movement detection method, device, equipment and storage medium. Background technique [0002] Motion detection (Motion detection) function has become a standard configuration of surveillance cameras (such as infrared-triggered surveillance cameras). This function is used for unattended surveillance, alarm, and video recording. The basic principle of motion detection is to take the image sequence collected by the camera as input, and calculate and compare it by the algorithm. When the picture changes (such as people walking, small animals passing, vehicles passing, etc.), the calculation results given by the algorithm The value will exceed the threshold and instruct the system to make corresponding processing (such as alarm, video recording, etc.). [0003] Due to the need for cost control, in surveillance camera products, the motion detection a...
