| 摘 要： | 针对单目运动像机无法确定点状运动物体三维位置的难题,提出了一种求解点状运动物体三维位置的方法,利用直线在其法平面上的投影为点这个特性,将各时刻像机光心与物体位置的连线(以下称观察视线)投影到以运动物体轨迹为法线的平面上,通过迭代使其投影线交于一点,交点对应的直线就是物体的运动轨迹,仅需要取大于等于5个时刻的数据就可以确...

| Abstract: | In order to determine the 3D position of a moving point from a monocular moving camera,a positioning method is proposed by taking advantage of the property that the projection of a line on its normal plane is a point,the projection lines of the line-of-sights on the plane which normal is the moving point trajectory intersect one point,and can get the trajectory of the point by 5 views.Firstly,that the moving point is constant velocity is supposed,the initial guess can be calculated by the linear equation se... |
