摘要
在摄像机以某一角度俯拍地面的情形下,推导了一个从地面各点到摄像机图象间的变换公式,也得到了从摄像机图象中各点到地面的变换公式。这两个变换互为逆变换。给出了变换实例。利用这两个变换进行了机器人定位,得到了一种机器人定位的新方法,给出了实验结果。
When a camera gets the image of the ground with a certain angle,the mapping formula from anywhere on the ground to the image taken by the camera is deduced ,and the mapping from the image to the ground is also gotten. These two mappings are inversive to each other.The example of the mapping is given.A novel approach for robot localization is gotten through the mapping.The experiment result is also given.
