Abstract

The invention provides a moving target detection method and device, equipment and a readable storage medium. The method comprises the steps of obtaining a video sequence frame image; performing movingtarget detection on the current frame image by adopting a Gaussian mixture model to obtain a first moving target binary image and a current frame background image; performing moving target detectionaccording to the current frame of background image and the five frames of images corresponding to the current frame of image by adopting an improved five-frame difference algorithm to obtain a secondmoving target binary image; performing OR operation on the first moving target binary image and the second moving target binary image to obtain a total moving target binary image; and performing morphological processing on the total moving target binary image to obtain a moving target. The moving target detection accuracy of the improved five-frame difference algorithm is improved, the existing smear problem is basically eliminated, or operation is carried out on the moving targets detected by the two algorithms to obtain all the moving targets detected by the two algorithms, and the detectedmoving targets can have complete contours.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of visual image processing, and in particular to a method, device, equipment and readable storage medium for detecting a moving object. Background technique [0002] With the advancement of science and technology, the visual image processing technology with computer as the core has also been developed rapidly. As a core content of visual image processing, moving target detection has been widely used in many fields such as intelligent monitoring, medicine and military affairs. [0003] There are many types of existing moving target detection algorithms. It can be roughly divided into optical flow method, frame difference method, and background subtraction method. Due to the complexity of its algorithm and high hardware requirements, the optical flow method is rarely used. The current mainstream moving target detection algorithms are frame difference method and background subtracti...
