摘要
本文提出一种基于查表技术知识的基角点提取方法．就一定的考察点数目来说，该方法由于采用了人的知识，其检测效果是很好的．由于采用了查表技术，该方法的速度非常快，并且易于硬件实现．当用硬件实现该方法，对于５１２×５１２的真实图像，角．点提取能以电视速率进行．本文详细讨论了查找表的构造方法和知识的采集方法．实验表明该方法工作得很好．
This paper proposes a knowledge-based method for corner detection that uses the look up table(LUT)technique.The organization and knowledge acquisition method are presented.As human knowledge is involved in the new method, the quality of corner detection is among the best for definite observing points.Algorithm using this method works very fast and is easy to be implemented by hardware.While using hardware,corner detection can be done in TV rate for a practical image of size 512×512. Experiments show hat this method works well.
