摘要
对网球发球图像路径进行有效修正,可以提高网球训练和比赛的水平。进行网球发球图像路径修正时,针对发球动作呈现旋转多维特征的特点,需要对失误点的角点进行标记,传统方法采用临界节点控制方法实现肢体特征提取,完成发球图像路径修正,但是不能对发球过程的失误点进行标记,降低了路径修正的准确性。提出一种基于计算机视觉特征提取的网球发球图像路径修正优化建模方法。构建了基于远程视频监控的网球发球动作的视觉特征采集系统,通过数据采集系统采集到的视觉图像作为特征分析的信息源,采用图像处理方法对采集的视觉图像进行边缘分割算法设计,以此为基础进行发球动作失误点的角点标记,实现网球发球图像路径修正优化建模。仿真结果表明,采用上述算法实时性和准确性较好,性能优越,能准确跟踪球员在发球过程中的视觉边缘信息特征点,并通过专家系统进行实时评判和指导,有效的对网球发球图像路径进行修正,提高发球技能。
An optimization modeling method for path correction of tennis serve image is proposed based on visual feature extraction of computer. Firstly,the visual feature acquisition system of serve action is built based on remote video monitoring. Then,the visual image collected by the data acquisition system is used as the information source of feature analysis,and the image processing method is used to make the design of edge segmentation algorithm on the collected visual image. Finally,the corner of serve fail point is marked on that basis to achieve the optimization mod- eling for path correction of tennis serve image. The simulation results show that the algorithm mentioned above has good real - time performance and accuracy. It has superior performance and can track the feature point of visual edge information during serve process. In the ,neantime,it can correct the serve image path effectively and improve the serve skill using the expert system to make real time judgement and guidance.
