Abstract

The invention discloses a moving target detection method and device, and relates to the technical field of computers. One specific embodiment of the method comprises the following steps: obtaining a background image of a current frame image by adopting a background subtraction method and detecting a first moving target in the current frame image; detecting a second moving target in the current frame image based on an inter-frame difference method and the background image; and performing logical operation on the first moving object and the second moving object so as to detect the moving objectin the current frame graph. According to the embodiment of the invention, the technical problems of cavities, double images, ghosting images and illumination sensitivity which are liable to occur in moving target detection can be solved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for detecting a moving object. Background technique [0002] There are many types of algorithms for moving object detection, which can be roughly divided into three categories: optical flow method, inter-frame difference method and background subtraction method. Due to the complexity of its algorithm and high hardware requirements, the optical flow method is less used now; the current mainstream moving object detection algorithm is the frame difference method and the background subtraction method. [0003] In the process of realizing the present invention, the inventor has found that there are at least the following problems in the prior art: there are holes in the inter-frame difference method, the contour is incomplete, the moving target is easily elongated, and there are "double shadows" (foreground in the previous frame image). Pixels are still detected...
