Problems solved by technology
[0004] In the process of realizing the present invention, the inventors have found that there are at least the following problems in the prior art: when the color of the pixels in the moving target is the same or similar to the color of the pixels in the background, the existing technology is easy to mistake the pixels of the moving target The pixels judged as the background make it difficult for the moving target to be completely detected

Embodiment Construction
[0025] The technical solutions of the embodiments of the present invention will be described in further detail below with reference to the drawings and embodiments.
[0026] figure 1 It is a flow chart of a moving target detection method provided by Embodiment 1 of the present invention, such as figure 1 As shown, the method includes:
[0027] Step 101, generating the first moving target image of the current frame input image;
[0028] Step 102, matching the current appearance model with the first moving object image of the input image of the current frame;
[0029] Step 103, according to the current appearance model matched with the first moving object image of the current frame input image, query the pixel points in the first moving object image of the current frame input image that meet the set rules;
[0030] Wherein, the setting rule may be: the probability value corresponding to the pixel point in the current appearance model is greater than the set threshold;

The embodiment of the invention discloses a method for detecting a moving target and a device thereof. The method comprises the following steps of: generating a first moving target image of a current frame input image; matching a current appearance model with the first moving target image of the current frame input image; inquiring pixel points which correspond to a setting rule in the first moving target image of the current frame input image according to the current appearance model which is matched with the first moving target image of the current frame input image; and setting the pixel points which correspond to the setting rule in the first moving target image of the current frame input image to be pixel points of the moving target, and generating a second moving target image of the current frame input image. By modifying the pixel points which are falsely judged to be background in a first detecting result image to be the pixel points of the moving target through the current appearance model, the technical scheme of the embodiment leads a second generated detecting result image to comprise more complete pixel points of the moving target, thereby more completely detecting the moving target.
Description
technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for detecting a moving object. Background technique [0002] Moving object detection technology is the basic technology of monitoring system, recognition system and other systems related to video processing. Systems related to video processing detect moving objects through moving object detection technology, and perform various follow-up processes such as classification, tracking, and identification of moving objects. key technologies. [0003] In the prior art, the commonly used moving object detection technology is the moving object detection technology based on the GaussianMixture Model (hereinafter referred to as: GMM) algorithm background modeling. The background model is updated according to the previous frame image, and the current frame image is calculated. The pixel belongs to the probability of the updated background model, and the moving ...
