摘要
在ICT图像实体重建技术中,需要进行实体轮廓的边缘检测和特征识别。本文采用Sobel算子对图像进行边缘检测,得到图像的边缘点,通过多次过滤进行边缘细化;然后根据轮廓跟踪准则对边缘点进行排序,将图像数据转化为具有单像素宽的轮廓线;最后对轮廓线加以识别,用线段来表示实体的同一特征体素。
In the model reconstruction of existing products on base of the ICT scanned images, theapproaches of edge detection and pattern recognition are proposed. In this paper, alledge points are detected by using Sobel's methods, and processing edge by usingmorph thining methods. Then all edge points are sorted by rule of edge following; Finally,The Contour of Model are stored into lines by patten distinction.
