Device and method for image detection of total station bracket accuracy

Abstract

The invention relates to a device for image detection of total station bracket accuracy. The device comprises three CCD cameras, a plane reflector, a holding frame, a concentric gauge, a base and a computer. A measuring method comprises the following steps: on the basis of light reflecting principle, reflecting and forming four circular light spots in light tube CCD cameras by rotating a bracket, and then calculating perpendicularity and parallelism according to the four circular light spots; before and after rotating for 180 degrees, forming two circular light spots in the CCD camera at the top end by a reflecting circle at the top of the concentric gauge and calculating a center distance according to the coordinates of the centers of circle of the two light spots; calculating a distance of the centers of circles of inner and outer diameters of a circle formed in the CCD camera on the other side of the light tube through a circular end face of the concentric gauge and a bracket hole and calculating the coaxial degree of the bracket. According to the invention, an image detection method is adopted, no auxiliary tool is required, the measurement for the precision verticality, parallelism, coaxial degree and center distance of the bracket can be completed by a single person, the stability and the measurement accuracy both can reach u-level and the efficiency is increased.

Description

technical field [0001] The invention relates to a device and method for detecting the precision image of a total station support, which is suitable for detecting the perpendicularity between the two arms of the total station support and the vertical axis rotation plane, the parallelism of the two arms, the coaxiality of the left and right horizontal axis holes and the distance between the two arms The machining accuracy of the center distance of the vertical axis rotation axis. Background technique [0002] The total station is a surveying and mapping instrument system that integrates measurement functions such as angle, distance (slope distance, horizontal distance), and three-dimensional coordinates. It can be used in almost all measurement fields, especially in precision projects such as large-scale buildings and underground tunnel construction. field of measurement or deformation monitoring. As an important component of the total station, the bracket has a major impact ...

AI Technical Summary

Problems solved by technology

[0003] At present, manufacturers test the verticality of the two arms of the bracket and the vertical axis rotation plane, the parallelism of the two arms, the coaxiality of the left and right horizontal axis holes, and the accuracy of the center distance between the two arms and the vertical axis rotation axis. Each accuracy index requires different tools to be tested sequentially. There are disadvantages such as cumbersome procedures, complicated means, low efficiency, high cost, low production capacity, poor accuracy and repeatability of measurement results, etc.

Inspection work requires high eyesight of workers, and long hours of work will cause physical and mental damage to workers

Due to the higher and higher requirements for the production capacity and accuracy of the total station, the existing detection methods can no longer meet the demand
