A LINEAR ALGORITHM FOR ESTIMATING 3-D MOTION PARAMETERS BY USING OPTICAL FLOW
-
摘要: 三維空間中物體運動參數(shù)可以用二維平面光流及圖象平面上投影坐標求得。當物體表面結(jié)構(gòu)小于物體與投影圖象平面之間的距離時,算法是線性的。

Abstract: The 3-D motion parameters of object in space can be solved by using the 2-D optical flow and projection coordinates in image plane-This algorithm is linear, if the dimension of surface structure of motion object is smaller than the distance between the object and its projection image plane. -
