摘　　要：在三维测量技术中,传统的双目立体视觉方法计算量大,对没有明显特征的图像,匹配精度较低。本文将基于结构光的三维测量技术与双目成像技术相结合,解决了特征点搜索的困难,提高了测量的精度。与传统结构光成像技术相比,采用常规的双相机立体标定,不需要进行投影仪标定,降低了系统的复杂性,提升了系统的可操作性和灵活性。最后,运用该技术进行三维测量实验,测量结果表明了该技术的可行性。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 3 D 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 3 D measurement experiment is carried out and the experimental results show the feasibility of the technology.
