Abstract

The present invention provides a moving object detection method and system. The method comprises: performing denoising processing of video images; setting a background frame image; calculating difference image between a current image and the background frame image; performing binary processing of the difference image, extracting the foreground object of a target moving object, and calculating the proportion of the foreground pixel points of the foreground object; and confirming if the proportion of the foreground pixel points exceed a preset threshold, prompting that the moving object is detected. The moving object detection method improves the detection effect, simplifies the operation process and reduces the detection difficulty through a real-time background updating mode.

Description

technical field [0001] The present invention relates to the field of video image processing, and more specifically, to a method and system for detecting a moving object. Background technique [0002] At present, video moving object detection is an important part of the computer vision research field. Moving object detection is an important link in video automatic analysis technology. The main content is to separate interest events from video sequences. Video moving object detection is widely used in video intelligent monitoring, video compression, video retrieval and image enhancement. In the actual video processing process, factors such as light intensity and background changes in the video will have a certain impact on the detection process. [0003] In the prior art, there are mainly three methods for moving object detection technology, which are optical flow method, background difference method and frame difference method. Among them, the calculation process of the opt...
