一种运动图像标志点识别跟踪方法的研究

Study on the Marker Recognition and Tracking for Motion Image

提出了一种运动跟踪方法。该方法通过对人体目标图像进行差分消影和遗传恢复 ,能够从自由背景中识别出人体运动图像的标志点 ,可以提高基于普通摄像机的人体运动分析系统对环境的适应性。初步的应用结果表明 ,这种方法对实验环境要求低 ,鲁棒性强 ,识别率高 ,不仅可以用于人体运动分析 ,而且对在其它自由背景下运动目标的自动跟踪也有很大的应用潜力。

A new motion recognition algorithm is proposed. Through handling the object images with background removal difference algorithm and shape recovery genetic algorithm, this algorithm obtains precise coordinates of markers adhering to the body under a free background. It can enhance the environment adaptability of ordinary CCD based human motion analysis system. The results of the prelimitary experiments show that this algorithm has little restriction on environment, great robustness, and high recognition rate. It can not only be applied in the field of human motion recognition, but also in other research fields of automatic tracking.
