Embodiment Construction

[0048] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0049] figure 1 express figure 1 A target tracking device based on hierarchical feature matching according to the present invention is shown. Such as figure 1 As shown, the target tracking device based on hierarchical feature matching according to the present invention can include:

[0050] Target detection module 10 is used to extract the detection in the video scene from the background;

[0051]The target tracking module 20 is configured to record the position of the target in each frame through a series of processing based on the detection output by the target detection module 10 .

[0052] Wherein, the target detection module 10 can be realized by the "moving target detection method and device" which we previously applied for with the paten...

Abstract

The invention provides a target tracking device and method based on hierarchic type feature matching. The method comprises a target detection module, a feature extraction module, a target forecasting module, an occlusion isolation processing module, a matching coefficient calculation module, a matching decision module, a target information upgrading module and a tracking postprocessing module. Inthe invention, the concept of processing the occlusion target in a grouping manner is adopted to realize continuous tracking on the target in the occlusion event period. Robustness of occlusion trigger and isolation trigger under a noise-containing scene can be ensured through common restraint of overlapping criterion and area reasonableness criterion. Difference properties of features can be effectively utilized by a hierarchic type feature matching method, so as to lead the matching result to be more accurate.

Description

technical field [0001] The invention relates to image processing and video monitoring, in particular to a target tracking device and method based on hierarchical feature matching under the condition of target occlusion. Background technique [0002] With crime levels and threats increasing, security has become a worldwide concern. Video surveillance is one of the solutions to this problem. In addition to public safety, video surveillance can also effectively solve some other problems, such as the regulation of traffic flow and human flow in crowded cities. Large surveillance installations have been widely used in major places such as airports, banks, highways or city centers for many years. [0003] Because the traditional video surveillance technology is generally manual surveillance, there are many shortcomings such as easy fatigue, easy negligence, slow response speed, and high labor costs. Therefore, in recent years, people have gradually studied a digital, standardiz...
