| 摘 要： | 量化误差是采用光切法进行三维轮廓测量时的误差之一,主要来源于图像采集卡对CCD采集的图像信号进行数字化的过程。分析修正量化误差的4种方法,即直接拟合法、重心计算法、互相关计算法和边缘提取法,并对测试结果进行比较。

| Abstract: | The quantization error is one of the errors of 3D measure by light-section method.It is mostly from the digitization process of image signal which is captured by CCD.The four correction algorithms of quantization error,namely direct fitting method,centre-of-gravity calculation method,cross-correlation calculation method and edge extraction method,were analyzed.The test results of the four methods were compared. |
