摘　　要：研究了成像运动目标不动点的存在性、意义和性质，不动点的约束条件以及提取方法等内容．注意到目标在运动，且不同的目标有不同的运动速度和空间位置，当以速度向量的Ｘ，ｙ方向分量为坐标构成一个速度平面时，它们在速度平面上将对应于不同的不动点．研究了从图像平面到速度平面的约束变换，轻而在速度平面上分析和提取不动点特性．这些研究为各类运动目标的识别与跟踪提供了新的思想方法和技术途径．The existence of fixed points in a moving target of imaging and the meaning, features, constraint conditions as well as the extraction of its features are investigated. In an image plane, as thetargets are moving, the velocities and positions for different moving targets will be different. When avelocity plane is formed by velocity components in the x, y direction, the moving targets w ill havetheir corresponding fixed points in the velocity plane respectively. In order to extract the features offixed points, an analysis of constraint transformation from image plane to velocity plane has been carried out.
