一种基于先验知识的3D位姿参数识别方法

计算机视觉中用单幅照片来识别三维物体的六个自由度是非常困难的，但是，在知道一些先验知识的情况下，可以对物体的六个自由度进行识别。本文提出一种基于先验知识的三维位举参数识别的方法，使用物体上不共线的三个特征点及目标点来确定物体的位置和姿态，给出了六个参数的解析表达式，在实时处理中可以得到好的效果。

An Approach to 3D Position and Attitute Parameters Recognition Based on Perior Knowledge

In computer vision it is very difficult to recognize the six parameters (position andattitude) of a rigid body using single photo. But in the case that some perior knowledge are known,it ispossible for 3D position and attitude parameters recognition. This paper puts forward a method whichdetermines the six parameters and gives the equation of these parameters using three feature points andthe target point. This approach may act well in real-time processing.
