【摘要】 实现了一种快速回转式三维测量技术，脉冲调制的半导体激光器为光源，通过光学系统产生一线光源，投射到物体表面，ＣＣＤ摄像机获取的视频信号经过硬件电路实时处理后得到该光刀对应的物体位移量。回转平台每次转动１°，３６０°三维测量数据的获取仅须１５ｓ。文中介绍了这种三维数字化仪的基本原理和实现方法。更多还原

【Abstract】 A technology of fast 360 degreees 3D Profile measurement is realized. A laser diode used as light source produces a slit which is projected onto the surface of an object via a group of optical lenses. A CCD camera can grab the reflect curve line and its video output is processed by special hardware circuitries. Then the surface height value which the slit directs to will be directly obtained. The move table turns one degree each time and totally 360 degrees 3D information acquisition need only 15s. The principle and realization are presented.更多还原
