Problems solved by technology

[0005] At present, although theodolite measurement based on the prism coordinate system and the laser tracker measurement based on laser ranging can solve certain engineering problems, under certain conditions, such as the measurement of spacecraft products with complex spatial structures and many measurement items, a single The measurement method still has certain limitations when it works independently, so it is necessary to find a method to establish a relationship between the electronic theodolite and the laser tracker measurement coordinate system to form a joint measurement system

Abstract

The present invention discloses a method for establishing a joint measurement system based on an electronic theodolite and a laser tracker, wherein a coordinate system for the electronic theodolite, a coordinate system for a prism and a coordinate system for the laser tracker are established respectively. Meanwhile, the coordinate system for the prism is led into the coordinate system for the laser tracker, so that the transformation relation between the electronic theodolite and the laser tracker is established. The invention provides a method for leading the coordinate system for the prism into the coordinate system for the laser tracker, and further establishes the transformation relation between the electronic theodolite and the laser tracker. Therefore, the joint measurement is realized. The method is simple and easy to realize, high in efficiency, and wide in application prospect.

Description

technical field [0001] The invention belongs to the technical field of non-contact measurement. Specifically, the invention relates to a method for establishing a joint measurement system of an electronic theodolite and a laser tracker by using a prism and a target ball. Background technique [0002] In the assembly process of aircraft, rockets, satellites and other aerospace products, it is usually necessary to complete a large number of complex measurement work. At present, non-contact measurement methods represented by electronic theodolite and laser tracker have been applied more and more. Based on the principle of forward intersection, the electronic theodolite has extremely high angle measurement accuracy. The laser tracker uses laser ranging technology to track and measure space targets in real time. [0003] The prism is a commonly used auxiliary tool in the assembly accuracy measurement of aerospace products using theodolite. It is generally made of quartz crysta...
