【摘要】 三维曲面轮廓的测量,传统方法都是采用表面轮廓仪或三坐标机测量,改进的方法有的是将激光三角测量头装在三坐标机上代替触针从而实现非接触测量,但这种改进方法仍然受到三坐标机本身的限制。本文在深入研究激光三角测量原理的基础上,提出了一种三维曲面的激光双三角测量法并给出了设计要点。更多还原

【Abstract】 Traditionally, the surface contour instrument or three-coordinate machine was used in 3-D curued surfaces measuring system. Now triangle measuring device using laser is installed on the three-coordinate machine and replaces the contact pin. But this method is still limited by the three-coordinate machine itself. On the basis of studying the principle of trinagle the measuring method,this paper has put forward to the two-triangle measuring system and given out the designing method.更多还原
