为了提高对单手肩上投篮动作的准确性,需要对单手肩上投篮动作进行检测,为此提出基于激光图像分析的单手肩上投篮动作激光位移检测技术。采集图像和研究图像关键特征点分布,进行单手肩上投篮动作激光图像特征分析和位移检测处理。基于特征标记方法,进行单手肩上投篮动作的激光特征分析和图谱特征检测,结合模糊图像位移检测技术,进行单手肩上投篮动作的特征分析,采用边缘轮廓特征检测方法,进行激光条纹图谱分析,根据光分辨特性激光位移检测的误差修正和补偿处理,结合形状特征分布实现对单手肩上投篮动作激光位移检测。仿真结果表明,采用该方法进行单手肩上投篮动作的激光位移检测的图谱分辨能力较好,位移参数估计准确性较高,最高检测精度已到达100%,误差较低,最低可达到1%,而且检测时间也低于另外两种方法,最多不超过2 s,有效实现了对单手肩上投篮的动作修正,提高投篮的准确性。
In order to improve the accuracy of one hand shoulder shooting,it is necessary to detect one hand shoulder shooting.Therefore,the laser displacement detection technology of one hand shoulder shooting based on laser image analysis is proposed.Collect image and study the distribution of the vital feature points of the image,and carry out the laser image feature analysis and displacement detection processing of one hand shoulder shooting action.Based on the feature mark method,the laser feature analysis and map feature detection of one hand shoulder shooting action are carried out.Combined with the fuzzy image displacement detection technology,the feature analysis of one hand shoulder shooting action is carried out.The edge contour feature detection method is used to analyse the laser stripe map.The error correction and compensation processing of laser displacement detection is carried out according to the optical resolution characteristics,combined with the shape characteristics.Sign distribution is used to detect the laser displacement of one hand shoulder shooting.The simulation results show that the spectral resolution of the laser displacement detection of one hand over shoulder shot is good,and the estimation accuracy of displacement parameters is high.The maximum detection accuracy has reached 100%,the error is low,and the minimum can reach 1%.Moreover,the detection time is lower than the other two methods,which is no more than 2 seconds,which effectively realises the action correction of one-handed shoulder shot High shooting accuracy.
