Manual programming is inefficient when using CNC pipe cutting machine cuts intersection lines with welding groove.
使用数控切管机切割带焊接坡口的相贯线时，手工编程效率低下。
An image with intersection lines between grating planes and a known objective plane can be captured by a digital camera.
将光栅投影到已知目标平面，通过数字摄影得到光栅平面与目标平面相交的光栅图像。
Further, the visibility of intersection lines could be determined by projection model. The occlusion matrix made up for the lost depth information during projection.
引入遮挡矩阵存储遮挡信息弥补了投影降维后造成的深度信息损失。
