摘　　要：针对当前序列影像直线运动目标追踪准确性较低、稳定性较差的问题,提出基于Vicon动作捕捉的序列影像直线运动特征跟踪匹配算法。采集序列影像直线运动特征,通过对序列影像特征进行自身适应过滤声波处理完成图像滤噪,根据不同角度序列影像的特征点及局域像素方向梯度特征实现图像数据的维度转换。并提取序列影像特征关联规则,进行特征等级的划分,根据提取和划分结果进一步对序列影像直线运动跟踪方法进行优化,针对不同特征等级进行跟踪特征点的匹配处理,实现对序列影像直线运动特征的跟踪匹配。通过实验证实,基于Vicon动作捕捉的序列影像直线运动特征跟踪匹配算法具有更高的准确性及稳定性,充分满足研究要求。Aiming at the problems of low accuracy and poor stability of linear motion target tracking in current serial images,a linear image feature tracking and matching algorithm based on Vicon motion capture is proposed.The linear motion characteristics of sequence images are collected,and the image noise is completed by self-adaptive filtering and sonic processing of the sequence image characteristics.The dimensional conversion of the image data is achieved according to the feature points of the sequence images at different angles and the local pixel direction gradient features.And based on the extraction and classification results,the linear motion tracking method of sequence images was further optimized,and the matching processing of tracking feature points was carried out for different feature levels,so as to realize the tracking and matching of linear motion features of sequence images.It is confirmed by experiments that the linear motion feature tracking and matching algorithm for sequence images based on Vicon motion capture has higher accuracy and stability,and fully meets the research requirements.
