Device and method of three-dimensional coordinate measurement of object surface points

A measurement method is configured to measure the three-dimensional coordinates of each point of an object surface to be measured in the non-contact mode. The method comprises: storing the algorithm for calculation of the three-dimensional coordinates of an object surface point to be measured in advance; controlling a driving device to drive a distance sensor installed thereon to move to a plurality of different measurement positions to measure the distances among the driving device and a plurality of points to be measured of the object surface to be measured; obtaining distance measured by the distance sensor at each measured position and a position parameter value, measured by a position sensor, of the distance sensor located at each measurement position; and determining the value of a reference coordinate system parameter, and calling the algorithm according to the determined value of the reference coordinate system parameter and the obtained data to calculate the three-dimensional coordinates of each poin
