Problems solved by technology

However, practice shows that the existing moving target detection and tracking systems are far from mature. To develop a truly stable and practical system, a more robust core algorithm needs to be designed, and the above-mentioned target detection and tracking algorithms are either robust The stickiness is not strong, or the amount of calculation is relatively large, and most of them do not have the function of finding the target after the target is lost

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] figure 1 It is a schematic structural diagram of the moving object tracking device in the embodiment of the present invention.

[0015] Such as figure 1 As shown, the moving object tracking device 10 of the present invention has a moving image shooting unit, a collection and storage unit, and a control processing unit. In this embodiment, the moving image shooting unit is adopted as a camera 11 , the acquisition and storage unit is adopted as an image acquisition card 12 , and the control processing unit is adopted as a host computer 13 .

[0016] The camera 11 is fixed and kept at a certain shooting angle, and is used to acquire video analog signals within a certain area, and a moving target A of interest is contained within the area. Within the area monitored by the camera 11, the user 100 can track and retrieve the movement of the object of...

Abstract

The invention provides a method and a device for tracking motion objects on the basis of images. The method is characterized by selecting and tracking a target of interest and acquiring the color histogram of the target of interest. After the target of interest disappears, the color histograms of all the other motion objects in a picture are calculated; when the similarity between the calculated color histogram and the color histogram saved and acquired before the disappearing of the target reaches a certain threshold value, the target of interest can be recovered, and can be tracked continuously; a sensitive area is set when the target of interest disappears so as to increase the recover rage of the target. By the method for tracking the motion objects, the lost targets can be recovered automatically and tracked again. The device for tracking the motion objects is simple in structure and capable of working in fields with uneven lighting, and has high adaptability and robustness.

Description

technical field [0001] The invention relates to an object tracking method and device based on video surveillance, in particular to a moving object tracking method and device with a search function. Background technique [0002] As one of the important topics in computer vision research, moving target detection and tracking has important applications in research fields such as battlefield reconnaissance, video surveillance, image compression, image retrieval, and human-computer interaction. [0003] After decades of development, moving target detection and tracking technology has made great progress. At present, target detection and tracking algorithms mainly include background-based blob tracking, image-based moving object tracking algorithm (CamShift algorithm) target tracking, and based on Target tracking of texture features, etc. However, practice shows that the existing moving target detection and tracking systems are far from mature. To develop a truly stable and pract...
