Abstract
In this paper, a novel structure of 3D camera based on laser double triangulation displacement sensor is proposed. By placing two mirrors in the optical routes, double triangulation can be gotten by using only one CCD. Through designing the place and angle of these mirrors, the Scheimpflug condition could be met in whole measurement range of the sensor. And results of experiment have showed that this design could overcome some problems caused by inclination and blocking of work piece´s surface. This design makes the 3D camera much cheaper and improved the measurement precision
