Embodiment Construction

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the specific embodiments will be described in detail below in conjunction with the accompanying drawings.

[0039] figure 1 This is a flow chart of the steps of the method provided by the embodiment of the present invention. As shown in the figure, the target detection method is used for the image detection of the intelligent video surveillance system and includes:

[0040] Step 101: Obtain a current frame image;

[0041] Step 102: For the current frame image, use a mixed Gaussian model to perform foreground detection to obtain a foreground detection result; for the current frame image and the previous frame image of the current frame image, obtain a motion detection result through optical flow calculation;

[0042] Step 103: Perform fusion processing on the foreground detection result and the motion detection result to obtain a first detection result.

Abstract

The invention provides a target detection method and a device. The method comprises the following steps: step 1, obtaining a current frame image; step 2, adopting a mixed Gaussian model to carry out prospect detection for the current frame image and obtaining a prospect detection result; and obtaining a motion detection result by optical flow calculation for the current frame image and the formerframe image of the current frame image; and step 3, carrying out fusion processing on the prospect detection result and the motion detection result to obtain a first detection result. The invention overcomes certain inherent defects of the single target detection technology by a method of fusing a plurality of detection results, and can complete the target detection task in a complex scene.

Description

Technical field [0001] The invention relates to an intelligent video monitoring system, in particular to a method and device for target detection in the intelligent video monitoring system. Background technique [0002] Intelligent video surveillance first needs to separate the foreground target and the background, so target detection is a very critical and very basic step, and it is one of the core technologies in the intelligent surveillance system. [0003] In the process of implementing the technical solution of the present invention, it is found that in the target detection process of the prior art, it is very difficult to use a single target detection technology due to the influence of noise, multiple light sources, shadows, transparency, and occlusion. Complete target detection tasks in complex scenes. Summary of the invention [0004] The purpose of the embodiments of the present invention is to provide a method and device for target detection to solve the technical problem...
