摘要
探讨用最小二乘法解决空间直线方程的拟合问题.先拟合三个直角坐标系中的投影直线,再通过投影直线求出空间直线方程,并对拟合出来的三个不同的直线方程进行比较,选择最佳拟合方案.
The article probed into the least square method to solve the fitting problem of a straight line equation in space. First fitting the projective straight line in three rectangular coordinate system, second obtaining the straight line equation in space through the projective straight line, and comparing three different straight line equations, finally choosing the best fitting program.
