Abstract

The invention relates to a secondary reflector surface type detection method based on three-dimensional measurement and coordinate system conversion. The method includes the steps of dividing a secondary reflection tower into three sectors, arranging three common fixed targets respectively in the three sectors, drilling a pile on the ground below the center of each sector, installing a rotatable target on the top of the pile to serve as a common fixed target, testing mirror surface to be tested only after a target is attached to the mirror surface, measuring the target points in the same sector are measured, fusing the coordinates of all the aperture measuring points to a local coordinate system of the same sector after the measurement is completed under all the apertures in the same sector, transferring the local coordinate system of the sector to the world coordinate system, and finally carrying out error analysis through the curved surface fitting. The method belongs to active measurement, the requirement for the environment is low, and large-size object measurement can be realized. The multi-aperture measurement of an object can be realized, so that all points on the surface ofthe object to be measured can achieve optimal measurement.

Description

technical field [0001] The invention relates to a method for detecting the surface shape of a secondary reflection mirror based on three-dimensional measurement and coordinate system conversion, and belongs to the technical field of detection of the surface shape of a reflection mirror. Background technique [0002] Solar thermal power generation technology avoids the expensive silicon crystal photoelectric conversion process and greatly reduces the cost of solar power generation. Secondary reflection tower solar thermal power generation uses a certain number of heliostat arrays on the ground to reflect the sunlight to the secondary reflection mirrors placed on the top of the tower, and then focus the sunlight into the heat absorber on the ground. , heat the molten salt medium and drive the generator set to generate electricity, thereby converting the absorbed solar energy into electrical energy. Among them, the tower-type secondary reflector is assembled from several struc...
