Abstract

The invention provides a stable moving target detection method and a device. The stable moving target detection method comprises the following steps: moving targets in the current frame of image are detected; each moving target in the current frame of image and each moving target in the former frame of image are matched; according to a matching result, the appearing frame number of each moving target in the current frame of image in historical continuous image frames is subjected to increasing and decreasing treatment; and a moving target whose appearing frame number is larger than a first preset value is selected, and the selected moving target is tracked. According to the technical scheme of the invention, error detection or switched tracking of the moving target caused as the size of the moving target changes or the moving target suddenly appears or disappears can be avoided, the problem that the tracking picture is not smooth and stable can be solved, and algorithm is simple and effective.

Description

technical field [0001] The invention belongs to the field of image processing, in particular to a method and device for stably detecting a moving target. Background technique [0002] Based on the background difference detection of motion detection, the size of the moving target changes randomly, and some moving targets flicker, which affects the tracking of the main moving target, resulting in unstable and frequent switching of the camera tracking screen. [0003] Therefore, there is a need for a method for stably detecting a moving target, so that the picture of the pan-tilt camera is smooth when tracking. Contents of the invention [0004] The present invention provides a method and device for stably detecting moving objects to solve the above problems. [0005] The invention provides a method for stably detecting a moving target. The above method includes the following steps: detecting moving objects in the current frame image; matching each moving object in the curr...
