Embodiment Construction

[0061] The present invention will be further described below in conjunction with the accompanying drawings.

[0062] For complex scenes with rapidly changing environments, the present invention proposes a moving target detection and tracking method combining the frame difference method and the mixed Gaussian model. By combining the frame difference method and the mixed Gaussian model algorithm, the currently acquired video can be The change of the moving target can be accurately detected in the image, and at the same time, the tracking method can perform real-time tracking processing on multiple moving targets. The method for detecting a moving object and the method for tracking a moving object will be described in detail below.

[0063] refer to figure 1 , is a flowchart of a moving object detection method according to the present invention, including the following steps 101 to 107.

[0064] In step 101, a background model is established and initialized:

Abstract

The invention discloses a moving target detecting and tracking method combining a frame difference method and a Gaussian mixture model. The method includes the following steps: acquiring a video image, and carrying out difference calculation on a current frame of input video image and a previous frame of video image to get an inter-frame difference image; using an initialized Gaussian mixture model algorithm to process the video image acquired to get a foreground region image and a background region image of the input video image; fusing the inter-frame difference image and the foreground region image to get a fused video image; binarizing and morphologically processing the fused video image to get a moving target image in the current input video image; and matching the moving target image extracted from the current input video image with a moving target image extracted from the previous frame of video image, and getting a moving target tracking result according to the matching result. By combining the advantages of two target detection algorithms, accurate and real-time detection of a moving region is realized.

Description

technical field [0001] The invention relates to the technical field of video image processing, in particular to a moving target detection and tracking method combined with a frame difference method and a mixed Gaussian model. Background technique [0002] Video open class is a very effective means of narrowing the educational gap between urban and rural areas and between the east and the west. Therefore, as a technical method of recording video open classes, the intelligent classroom video recording and broadcasting system has developed rapidly. The intelligent classroom video recording and broadcasting system is an educational technology system that uses multimedia technology and computer network technology to record classroom teaching in real time. It does not require manual operation during the recording process of the entire classroom teaching, and only needs to place the camera at a fixed position in the classroom. , under the control of the computer, using the image pr...
