Measurement Errors Analysis of 3-D Profilometry Based on Linear Coding Structure Light Having Isosceles Triangle Teeth
摘要
对具有等腰三角形齿结构的线性结构光编码的三维面形测量技术(LCP)进行了误差分析, 推导了由于随机电噪声、 相移误差带来的测量误差, 并利用计算机系统仿真研究了量化误差、 光学系统误差等对测量结果的影响, 且对理论分析的结果进行了验证。
Abstract
The measurement errors of 3-D profilometry based on linear coding structure light having isosceles triangle teeth are analyzed. The formula and the effect of the errors caused by the CCD camera, image grabber, quantization, optical system and phase-shifting are given, and the results are verified by the computer simulation system.
