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

A laser tracking measuring system is provided with laser tracking measuring instrument and a movable target.The laser tracking measuring instrument comprises a base, a horizontal rotation platform, a support and a vertical shaft, wherein a main transverse shaft is arranged on the support, a first main observing device is fixed on the main transverse shaft, and a connecting rod is arranged on the main observing device; a shaft rack is arranged on the connecting rod, and an auxiliary shaft is arranged on the shaft rack; a first auxiliary observing device is fixed on the auxiliary shaft, and a first main observing line and a first auxiliary observing line are located on the same plane; the movable target is provided with a semispherical seat and a PSD sensor fixed on the semispherical seat, and the sphere center of the semispherical seat is located on the photosensitive face of the PSD sensor.The laser tracking measuring system has the advantages that the electronic system is simplified greatly while tracking measuring requirements are satisfied, actual light speed needs not to be considered during distance measuring, measuring of temperature, air pressure and the like is not needed before use, and meteorological correction is not needed.

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...
