This paper presents the two conditions:Sufficient condition and necessary condition for the links of perspective mapping and projective mapping.

本文给出了射影映射为透视映射的两个充要条件 ,这两个充要条件与射影变换为对合的充要条件是一致

With inverse perspective mapping obtained through inverse conversion following the perspective mapping principle of a video camera,the position of an obstacle in the world coordinate system was established by computing the position of an obstacle in an image plane.

介绍了移动机器人视觉处理中摄像机技术的相关内容,并根据摄像机透视映射原理,进行逆换算从而得到逆透视映射,即根据物体在成像平面坐标系的数据及其摄像机参数得到其在世界坐标系的具体参数数据,得到了实用的控制算法,从而实现了利用单摄像机获取环境的深度信息,简化了系统的结构。

According to the problem in obstacle avoidance of the mobile intelligent robot under uncertain environment,deep information of environment has been acquired based on inverse perspective mapping theory.

文章针对环境信息不确定情况下的避障问题,利用摄像机逆透视映射原理,实现单摄像机获取环境深度信息,并提出了一种基于视觉的局部路径规划的算法,实现了移动智能机器人在不确定环境中利用视觉传感器实时获取外部信息进行路径规划,仿真与实验结果表明,移动智能机器人能快速地跟踪规划路径,实现避障。
