Paper Abstract

The goal of structured light techniques is to measure the shape of three-dimensional object using automatic non-contact techniques and based on trigonometry measurement. This thesis deals with the device of obtaining range image based on multi-line structured light. The projector is taken as the projecting source of this device and can project multi-line structured light. The digital camera is taken to obtain stripe image and can capture the stripe image in a single frame. The technique of space encoding is utilized to process the stripe image and could avoid the aliasing of the multi-line structured light. This technique can ensure the veracity of the range image obtaining. The experiments have shown that the range image obtained by this device have better results and higher speed of acquisition. Measuring range of this device is 200mm(X)×120.0mm(Y)×150.0mm(Z). The measuring error of Y and Z direction is less than 0.3mm. The measuring error of X direction is less than 0.1mm.The absolute error of the measurement result in the direction of Z is less than 0.2%.
