本文研究了摄像机有机动,而点目标在短时间内作匀速直线运动的情形.研究表明,只要点目标——摄像机相对运动方程满足可观测性条件,那么就可从三幅序列图像中确定点目标的三维运动参数,进而估计出它的空间坐标.文中还对算法的抗干扰能力进行了分析,结果表明,摄像姿态以及点目标——摄像机相对运动方程的曲率是影响算法抗干扰能力的两大因素。最后给出了计算机模拟结果.
In this paper, we study the case where the camera is moving while the point is moving at a uniform speed in a short period of time.The research shows that as long as the point-camera relative motion equation satisfies the observability conditions, the point can be determined from the three sequence images The target’s three-dimensional motion parameters, and then estimate its spatial coordinates.The anti-interference ability of the algorithm is also analyzed.The results show that the attitude of the camera and the point target - the curvature of the relative motion equation of the camera is two Big factor Finally, the computer simulation results are given.
