Method, device and system for detecting assembly precision of target object

Abstract

The invention discloses a method, a device and a system for detecting the assembly precision of a target object. The method comprises the steps of determining a plurality of first feature points of the target object in a first direction according to a width value of the target object; acquiring a first coordinate value and a second coordinate value of each first feature point; determining a theoretical value of the second coordinate value according to the first coordinate value and a preset parameter value; then determining the assembly precision of the first feature points; determining a plurality of second feature points of the target object in a second direction according to the plurality of first feature points of the target object in the first direction; acquiring a third coordinate value and a fourth coordinate value of each second feature point; determining a theoretical value of the fourth coordinate value according to the third coordinate value and the preset parameter value;then determining the assembly precision of the second feature points; and determining the assembly precision of the target object according to the assembly precision of the plurality of first featurepoints of the target object in the first direction and the assembly precision of the plurality of second feature points of the target object in the second direction.

Description

technical field [0001] The invention relates to the field of digital measurement, in particular to a method, device and system for detecting assembly accuracy of a target object. Background technique [0002] With the development of solar thermal power plants in China, solar thermal power generation, as a new field of solar thermal technology application, has come from behind in the solar thermal utilization industry, and its development momentum is very rapid. Solar thermal power generation technology is mainly divided into trough type and tower type. , dish type and Fresnel type, among which the trough type solar thermal power generation technology is the most mature. [0003] In the solar trough heating system, the positioning accuracy of the reflector of the trough solar collector has an important influence on the heat collection efficiency of the solar trough collector. When installing the reflector, due to factors such as manufacturing errors of the support device or ...
