摘要
本文针对传统投影光栅相位法的光学三角法模型进行了改进, 采用直入射光路并配合使用一种简便易行的标定方法, 只需使用相移公式求取相位差, 而不会引入与系统几何位置关系有关的量, 简化了求取高度矩阵的要求。实验结果表明, 新系统模型精度良好, 测量误差为0107 mm。采用该模型和标定方法可以克服传统方法系统模型的局限性, 最大限度减少误差源并提高抗干扰性。
Abstract
In this paper, the traditional optical triangulation model based on phase method is improved, and a new model and calibration method are used which is independent of geometric parameters. The new model requires only calculating phase difference thorough phase shift formula without adding any geometry position parameters, which simplifies the requirement of resolving the altitude matrix. Parallel tests show with the new model, a measurement error of 0107 mm is reached, showing a good accuracy. Through the study of this paper. This new model calibration method can overcome the limitations of traditional method and minimize the error sources as well as improve the capability of anti-interference.
