Abstract

The invention provides a target object tracking method based on color-structure characteristics in order to overcome the defects of high complexity and low accuracy of the tracking of moving objects in video images in the prior art. The method includes: object detection of an image in a video is performed, at least one object in the current frame of image of the video is obtained, ultra-pixel segmentation of the object is performed, and the color characteristic and the structure characteristic of the object are determined; a to-be-tracked target object is determined in the current frame of image via comparison and matching of the color characteristic and the structure characteristic of a to-be-tracked object in a preset object model database, and position information of the target object in the current frame of image is recorded; and the target object is tracked in the next frame of image of the video according to the color characteristic and the structure characteristic of the target object in the current frame of image, and the position information of the target object is updated. According to the method, the accuracy and the robustness of target tracking with single texture for a video tracking algorithm are effectively improved.

Description

technical field [0001] The invention relates to the technical fields of pattern recognition and computer vision, in particular to a method for tracking a target object based on color-structure features. Background technique [0002] Augmented Reality (AR) technology can seamlessly integrate objects and information in the real world with objects and information in the virtual world generated by computers. More information and more convenient information acquisition experience, enhance people's understanding and perception of the real world. [0003] Video-based augmented reality technology has developed rapidly in recent years because of its low application cost and its universal application in various environments. How to accurately track objects in the real world is one of the keys to realize the combination of virtual and real in augmented reality technology. As the basis for the realization of augmented reality technology, target tracking technology based on video image...
