摘 要: 以手持式线激光源为工具 ,采用摄像方式 ,实现一种简便、易行的 3D表面快速反求建模方法 ;避免了复杂的光学系统、机电控制系统设计 ,只需在线激光源扫掠物体表面的同时 ,连续摄像 ,通过对光条图象序列进行处理 ,得到物体的 3D模型。文中给出了复杂形体的建模实例 。 A simple method to reconstruct the 3D shape of objects is presented. It differs from other conventional structured lighting approach in that it needn't any computercontrolled device to adjust the lighting plan of the laser source. In scanning process,the operator holds a line laser source and freely move it to cast light strips over the object,and a digital video camera is used to recorded the scene. The 3D shape of the object can be extracted from the lighting strips. Experiment on a complex shape is presented, and result is satisfied and can be used in the field of computer animation.
