This paper presents an iterative chaincodetracing method with parallel hierarchy for line segment detection.
提出了一种分层并行迭代式链码跟踪直线提取方法。

For binary image, chain-codetracing is used, and some sequent processing is applied to above tracing based on some prior knowledge so as to get the points of road boundary.
对二值图像运用改进的链码跟踪方法,再对链码跟踪结果运用先验知识进行处理,最后得到道路边缘点。

Firstly, using the contour tracing algorithm to trace the manipulated contour BMP, it has attained the contour point chain recorded by chain Code.
