介绍了一种由激光投影仪和摄像机组成的三维形状采集系统。用户用手将一束光投射到测量的3D场景中。投影光和LED标记连接到激光投影仪上，用摄像机捕捉。通过从标记的二维位置估计激光投影仪的三维姿态，可以计算到激光照射表面的距离。使用激光投影仪投射光条，可以从已知的3D表面校正形状估计误差。通过该系统，用户可以实时测量物体的三维形状，从而确定表面各部分的形状获取。
A 3D shape acquisition system consisting of a laser projector and a video camera is described. A user projects a stripe of light to the measured 3D scene by hand. The projected light and LED markers attached to the laser projector are captured with the video camera. By estimating the 3D pose of the laser projector from the 2D locations of the markers, the distance to the surface lit by the laser can be calculated. The use of a laser projector that projects a stripe of light enables correction of shape estimation errors from known 3D surfaces. With this system, the user can measure the 3D shapes of objects in real time, thereby confirming the shape acquisition of each part of the surface.
