摘要
为了利用现有图片资料重建管道的三维形态,文中首先将图像数字化并提取了相关信息,然后应用了数学形态学中图像腐蚀处理的思想,提出利用逐层去除边缘的算法求解每张图片中图像最大内切圆,较好的解决了图像三维重建问题。算法中采用了改进的边缘检测算子,该算子能够适合于各种形状图像边缘检测。这一算法在实际求解过程中取得了令人满意的结果。
In order to use existing images to reconstruct the 3D shape of pipelines, the images are digitized and the related information is extracted. Then the thought of image-erosion in mathematics morphology is applied. Finally an algorithm which is used to seek maximum inscribed circle by getting rid of image＇s edges layer by layer is presented. This algorithm is preferable in solving problems of rebuilding 3D shape of pipelines from images. An improved operator of image edge detection is used, which is fit for all kinds of shapes. The satisfactory results on practical use are showed.
