Research on the Algorithm of sample points data in the measurement of airplane surface rotation angle by photographic measurement method or laser tracker method, propose a high precise algorithm, that is creating a rigid plane and coinciding the plane’s start position to the end position by steps, uniting the rotation matrix of each step, finally calculate the angle. After analyzing the error of this algorithm, propose a method to select best three points that can reduce the error. At lase, Design a test to validate the precise. The result show that the coincide algorithm with three points has 0.05 degree error. This algorithm with this error meet the demand of airplane surface rotate measurement.
