Abstract: Among three-dimensional measurement technologies, traditional binocular stereo vision requires a large amount of computation and has low matching accuracy for images without distinctive features. The combination of 3D measurement technology based on structured light and binocular imaging technology is adopted to solve the difficulty in feature point searching and improve the accuracy of measurement. Compared with the traditional structured light imaging technology, the proposed method only needs a conventional dual stereo camera calibration instead of the projector calibration, which reduces the complexity of the system and improves its maneuverability and flexibility. Finally, the 3D measurement experiment is carried out and the experimental results show the feasibility of the technology.

Key words: 3D measurement, structured light, binocular stereo vision
