Error Analysis of Three-dimensional Reconstruction for Irregular Objects

The visual detection based on structured light is put forward to solve the problem of image matching for stereo vision in recent years. It is paid much attention in the industrial environment, especially in the three-dimensional automatic detection and object recognition. In this paper, it is discussed about the accuracy of visual inspection techniques based on structured light. There are some factors of affecting measurement techniques based on structured light, which are object material, edge detection algorithms, uneven lighting, and so on. The experimental results reveal that these three factors have a great impact on the accuracy of the model measurement of irregular objects.
