摘要
直角坐标下的拼接方法在测量三维物体特别是回转物体时碰到了困难。把拼接方法推广到圆柱坐标可以解决这一难题。推导了圆柱坐标下的拼接公式,给出了计算机模拟和测量的结果,其理论拼接误差为10-7mm数量级,验证了这种方法的正确性。最后给出了实际测量结果。
Multiaperture connection in Cartesian coordinates is difficult to be used to test suface of 3 D
object or rotating object. To solve the problem, multiaperture connection in Cartesian
coordinates is extended into cylindrical coordinates. Formulas in cylindrical coordinates are
given. Results of computer simulation show that the theoretical error is about 10 -7 mm,
which proves the method is correct. Testing results for a real cylinder are given.
