Problems solved by technology

The triangulation method requires a lot of positioning parameters in the application, and it is very cumbersome and time-consuming in the calibration of the measuring equipment. If a certain parameter in the system cannot be accurately obtained during the actual measurement, it will cause errors in the measurement data
The measurement electronics are far more complex than the pulse method

Abstract

The invention discloses a laser tracking and measuring system which comprises a laser tracking and measuring instrument and a moving target.The laser tracking and measuring instrument comprises a base, a horizontal rotary platform, a support and a vertical shaft, and a main transverse shaft is arranged on the support; a connecting rod is fixed onto the main transverse shaft, a first main observation device is fixed to one end of the connecting rod, a shaft bracket is arranged at the other end of the connecting rod, and an auxiliary transverse shaft is arranged on the shaft bracket; a first auxiliary observation device is fixed onto the auxiliary transverse shaft, and a first main observation line and a first auxiliary observation line are positioned on the same vertical plane; the horizontal rotary platform is in a manual rotation mode, the main transverse shaft is in a manual rotation mode, and the auxiliary transverse shaft is in a manual rotation mode; the moving target is provided with a hemisphere seat and a PSD (position sensitive detector) sensor, the PSD sensor is fixed onto the hemisphere seat, and the sphere center of a hemisphere of the hemisphere seat is positioned on a photosensitive surface of the PSD sensor.The laser tracking and measuring system has the advantages that electronic systems can be greatly simplified while tracking and measuring requirements are met, the actual light speed does not need to be considered in distance measuring procedures, temperatures, air pressures and the like do not need to be measured before the laser tracking and measuring system is used, and meteorological correction can be omitted.

Description

technical field [0001] The invention relates to a laser tracking measurement system. Background technique [0002] Laser tracking measurement can track space moving objects and measure their space coordinates in real time. Laser tracking measuring instruments currently on the market are mainly provided by LEICA in Switzerland, API in the United States, and FARO in the United States. It integrates the functions of laser interference ranging, photoelectric detection, precision machinery, computer control, and numerical calculation. [0003] When the existing laser tracking measuring instrument works, a moving target is attached to the measured target as a measuring target. When the moving target moves, the tracking head adjusts in real time under the control of the tracking servo mechanism, tracks the moving target and measures. The existing laser tracking measuring instrument adopts laser interference distance measurement. Although the accuracy is very high, the electronic...
