摘　　要：文章根据矩形目标边缘二值图的特点,提出一种基于直线段提取及其参数化的矩形目标重构方法,实现矩形目标位姿参数高精度快速求取。该文提出的矩形目标重构方法主要分两步进行:首先从矩形目标边缘图像的二值图中提取出所有直线段,并将直线段参数化;其次由参数化的直线段提取出近似矩形,再由近似矩形重构出精确的目标矩形,并计算其位姿参数。该文提出的算法可应用于机器人装配及目标跟踪中。According to the characteristics of the binary image of rectangular objects' contour,this paper presents a new rectangle contour reconstruction method based on lines extraction and parameterization,and realizes the position and orientation computing of rectangle objects fast and accurately.The reconstruction method falls into two steps:firstly,extracting all straight lines in the binary image of the rectangular objects' contour,and then parameterizing the extracted lines;secondly,finding out all the approximate rectangles based on the parameterized lines,and then reconstructing the precision rectangles,as well as computing the parameters of those rectangular objects' position and orientation.The algorithm presented in this paper can be used in work of robot assembly and object tracking.
