基于特征点位置及速度的空间非合作目标质心位置测量方法

Measurement of the Centroid for Noncooperate Target Based on Feature Points' Position and Velocity

对于空间非合作目标,地面上所用的质心位置测量方法难以实现。提出了一种应用摄像测量学实现质心位置测量的新方法。首先采用双相机对目标进行拍摄,通过特征点的匹配计算目标表面上特征点的位置及速度;再通过这些特征点的位置及速度,结合刚体运动学理论,计算目标的质心位置。仿真结果表明,本方法可以有效地实现目标的质心位置测量。

For noncooperate target in space, it＇ s difficult to realize the centroid measurement on the ground, a novel method that applies videometrics to position the centroid of noncooperate target is proposed. First, take photos of the target by binocular, calculate the feature points＇ position and velocity by feature match. Then, together with rigid kinematics, the centroid of the target can be positioned by the feature points＇ position and velocity. The simulation shows that this approach can position the centriod of target efficiently.
