太阳能电池板直线检测的切空间角度投影方法

摘要

In order to realize the rapid detection of the edge beeline of the solar panel,we propose a new pro⁃jection method based on tangent space,which can detect the edge line of the solar panel.We can get the edge information by the pretreatment,then transform the edge feature to the tangent plane representation.In tangent space,line is expressed as a horizontal line,and the angle of the horizontal line is the same as the straight line.The points on the horizontal line aggregates,resulting in a peak point after the angle projection. The peak point represents a beeline.So we realize the positioning of the edge beeline of the solar panel.The method is fast,anti noise ability is strong,and the accuracy can reach 97%.%为实现对太阳能电池板边缘直线的快速检测，文章提出基于切空间的角度投影方法。对太阳能电池板进行预处理，得到边缘信息，将其边缘特征进行切平面表示。在切平面内，直线表示成一条水平线，且该水平线的角度为直线的偏转角度。对切空间特征进行角度方向投影之后，该水平线上的点大量聚集，产生一个峰值点，该峰值点对应于原始直线。由此实现了对太阳能电池板边缘直线的定位。实验表明该方法速度快，抗噪能力强，精确度可达到97%。
