摘要
介绍总体最小二乘法进行二维坐标转换的原理和方法。通过具体工程案例,研究利用总体最小二乘法进行坐标转换,结果表明:与普通最小二乘法相比较,总体最小二乘方法能够提高坐标成果转换精度,但如果应用不当,则不如普通最小二乘法的转换结果。
The method and principle of two dimensional coordinate transformation based on total least squares are introduced . The total least squares are applied to a survey engineering example in two dimensional coordinate transformation . The results show that compared with least squares ,two dimensional coordinate transformation based on total least squares can improve the precision of transformation and deteriorate it if incorrect by using this method .
