Imaging Experiment

SIFT matching algorithm is used to carry out the binocular three-dimensional imaging. Active projection is introduced to solve the problem of low feature quantity and poor matching results in the matching process. By means of projection random speckle, the matching feature is increased, and the matching quality is greatly improved. According to the train running part of the three-dimensional imaging experiment, achieved a good imaging result. Compared with the Fourier profilometry in the active three-dimensional imaging technology. The experimental results show that the structured light projection binocular three-dimensional imaging has a better effect.

Different Parts

To improve efficiency of industry inspection, measuring method of part shape which combines laser linear scanning and binocular vision is researched. In the system, two cameras are located at certain angle, and linear structured light is projected onto the part surface to produce distorted laser light stripe, which is used as measure feature curve. Ordinary planar plate is used as the calibration template in system calibration and images of serial parallel lines bundle are displayed on it which are acquired simultaneously by the camera to produce image series. Calibration parameters are divided into several parts, so as to calibration of them so that interference between different parts can be eliminated significantly. Based on above works, system calibration and reconstruction of 3D coordinate are implemented successfully. Experimental result shows our method’s feasibility and effectiveness, thus good prospect can be expected to it.
