Abstract
The invention relates to a system for detecting the geometric dimension of a water outlet. Based on the laser ranging principle, the system detects spatial geometric dimension and verticality and symmetry of the submerged water outlet, the geometric dimensions of inside appearance and outside appearance of the water outlet, the position of a side hole and the dimensions of an angle of inclination, calculates the verticality of a centre line and the end face of the water outlet, and calculates the angle of the water outlet relative to a horizontal plane when the water outlet is fixedly arranged. The main method is realized by the following steps: performing laser ranging by utilizing the extension and contraction and angle adjustment of a pole probe reflector, and performing specific calculation and analysis on obtained data.
