Method, device and equipment for extracting moving target under dynamic background and storage medium

The invention discloses a method, a device and equipment for extracting a moving target under a dynamic background and a storage medium, and the method comprises the following steps: obtaining a video stream containing a to-be-detected target, and extracting a frame image in the video stream; initializing Gaussian mixture model parameters according to the pixel value of each pixel block in the frame image; performing Gaussian mixture model parameter updating according to matching of the pixel value of each pixel block in the current frame image and the Gaussian mixture model; carrying out differential operation on the background image to obtain a binary image, converting the binary image into a foreground picture of a target to be detected, and improving a foreground point judgment method; and matching the pixel value of each pixel block in the current frame image with the updated Gaussian mixture model, and carrying out moving target detection by adopting an improved foreground point judgment method.
