摘　　要：传统三维姿态矫正方法主要依据不同帧运动图像特征进行分析,由于非显著图像边缘容易同噪声混淆,导致不规则单帧运动图像特征受到噪声因素的干扰,图像特征质量降低,无法对运动图像三维姿态进行有效矫正,提出一种应用模糊核估计和仿射变换的三维姿态矫正方法,采用shock滤波器从不规则单帧运动图像中预测出显著图像边缘,对不规则单帧运动图像进行平滑处理,降低噪声的干扰,将显著图像边缘其当成全局图像三维姿态矫正的指导,针对不规则单帧运动图像的图像特征识别模糊问题,基于透视原理以及仿射变换原理,推导出不规则单帧运动图像三维姿态调整的策略,结合测定的运动图像旋转角度,对运动图像左右倾斜、水平旋转和垂直旋转的三维姿态进行调整,实现不规则单帧运动图像三维姿态的准确矫正。实验结果说明,在不同噪声的条件下,该算法可对运动图像的三维姿态进行准确的矫正,具有较强的抗噪性能。Traditional three-dimensional profile correction method mainly according to the analysis of different frame motion image characteristics, due to the significant image edge with confused noise, easy to lead to irregular single frame image characteristics affected by noise factors, quality of image features, unable to effectively correct image three dimensional attitude of sports, in this paper, a fuzzy kernel estimation and affine transformation of the 3 d posture correction method, the shock filter rules never single frame to predict significant image edge in the image, with irregular single frame image smoothing, noise interference, will significantly image edge as its global image three dimensional attitude correct guidance, according to the image characteristics of a single frame of irregular movement image recognition fuzzy problems, and on the basis of the principle of perspective affine transformation principle, deduces a single frame of irregular movement image three dimensional posture adjustment strategy, combined with the determination of the movement of the image rotation Angle, the motion image tilt, horizontal spinning and vertical spinning three-dimensional attitude adjustment, single frame to realize irregular movement image three dimensional posture correction accurately. Experimental results show that, under the condition of different noise, the algorithm for motion image three dimensional posture correction accurately, have stronger antinoise performance.
