Multi-functional precise intelligent measuring apparatus and method for geometric quantities

The invention relates to a multi-functional precise intelligent measuring apparatus and method for geometric quantities. According to the invention, the measuring apparatus with a cooperative-target-free measurement mode and a cooperative-target-existing measurement mode is designed; in the cooperative-target-free measurement mode, software is employed for controlling a rotary table to automatically scan the surface of a to-be-detected object so as to obtain distance from apparatus to to-be-detected object, the value of a two-dimensional angle is recorded, and the coordinates of the to-be-detected object are finally calculated; and in the cooperative-target-existing measurement mode, the accurate coordinates of a target point are measured by using a visual recognition and autocollimation system, or the coordinates of the to-be-detected object are input in advance and laser range finding is carried out at the same time, so the accurate coordinates of the to-be-detected object are obtained. The measuring appara
