Embodiment 1

[0023] Step 1, template matching: first select the vehicle as the moving target, the target is not blocked, target tracking adopts regional template matching; obtain the video sequence containing the target vehicle, make the initial frame into a template, and use the built-in vision development toolkit IMAQVision of LabVIEW IMAQLearnPatter4 function for template learning and training, and then use the template to search for pixel matching in the target area, use the IMAQMatchPatter4 function to complete the template matching process, record the number of matching pixels as 3000, and set the threshold Ta as 90 in advance, which is 3% of 3000. If the unmatched number is less than or equal to 90, the matching is successful, and the next frame matching search is performed, and then step 4 Kalman prediction is performed; if the unmatched number is greater than 90, the matching fails, and step 2 occlusion detection is performed;

Abstract

Provided is a target tracking method based on a LabVIEW. When a target is not shielded, area template matching is adopted in target tracking, and learning and matching of a template are achieved through a machine vision module in a vision and movement function library arranged in the LabVIEW; when the target is shielded, a certain or some invariance characteristics of the target are extracted, characteristic template matching is carried out, tracking is completed, a search algorithm is brought in the tracking process to carry out estimation hypothesis on the position state of the target at the next moment, accordingly, tracking can be achieved in real time quickly and accurately, the shielded target can be tracked accurately and stably, it is guaranteed that the target cannot be lost in the tracking process, the tracking speed is accelerated, and real-time performance and robustness of tracking are improved.

Description

technical field [0001] The invention relates to a target tracking method, which belongs to the technical field of machine vision and image processing, in particular to a target tracking method based on LabVIEW. Background technique [0002] At present, moving target tracking technology is the core topic in the field of computer vision, and it is also the key underlying technology of intelligent video surveillance systems. It has practical value in safety monitoring, traffic management, etc., and has the characteristics of flexibility and visualization. In the field of intelligent transportation, through the tracking of vehicle targets, the intelligent traffic information analysis system can use fixed camera equipment erected on urban roads or highways to obtain vehicle information on the road, so as to provide necessary information for the system terminal and automatically obtain , Record and analyze traffic accidents and call the police, record the information of illegal v...
