| 摘 要： | 利用散焦图像测距原理，研究了一种运动物体位移和姿态参数测量方法。该方法首先在物体上设置4个特征点，然后根据特征点的散焦图像的模糊程序分别计算出每个特征点的移动距离，再由4个特征点的移动距离最终确定物体的运动位移和姿态参数。实验表明，该方法测量原理简单，计算量小，能满足实时性要求，并具有一定的测量精度。 |

| Abstract: | A method for Measuring displacement and attitude of moving object based on the blur in defocused images was studied.First,four markers were set on the object.Then,the displacements of four markers were calculated respectively by the blur of their defocused images.Finally,The displacement of moving object along the optical axis and the attitude angles could be determined by those displacements of markers.The experimental result shows that the presented method was simple,less calculation,and could satisfy the requirement of measurement in real time.Its errors were also acceptable. |
