摘要

本文利用立体角的概念

研究了静止物体平面由于镜头摇摆产生的成象区域的变化

从而可由两幅图象求出镜头到物体平面的距离。该法优点是无需对运动前后两幅图象进行特征点选择和匹配

适用于物体在镜头逐渐接近时图象上出现较大透视变形的情况。

Abstract

In this paper the change of image area of a static object surface due to camerapanning is studied by meams of the concept of the solid angle

thus the distance from the moving camera to the object surface can be calculated using two images. The advantage of the method is that there need no feature point selection and matching for the two images before and after moving. It is suitable for the case of large perspective deformation when the camera is gradually approaching to the object.
