Fast Restoring Algorithm of Rectangle Object and Its Implementation on DSP

Abstract

Abstract: A fast restoring algorithm of fragmentary rectangle object is propos ed in this paper. Through the statistic and analysis to edge points of the recta ngle object, the algorithm picks on appropriate eigen-points and fitting them so that the profile of the object is restored. Its proved by experiment that the s ize, gradient and position of the object can be attained accurately. The advanta ges of this algorithm are the high precision, speed and performance. The algorit hm has been accomplished on the TMS320C6X DSPs platform.

摘要： 行统计分析，在此基础上选取合适的特征点并进行拟合，从而达到恢复目标外形特征的目的。实验测试表明，该算法能准确地获取残缺矩形目标的大小、倾角以及所在位置等几何参数。该算法的优势在于精度高、速度快、抗残缺能力强，且已经在TMS320C6X 系列DS P上得以实现。
