Analysis of optical theodolite Dynamic accuracy evaluation method

摘要

Optical theodolite dynamic accuracy evaluation has long been a difficulty in measurement system. In classical method, it is based on positioning technology to calculate the angles. But this can't meet the accuracy requirement of evaluation needs. In this paper, we introduced regress-to-center correction theory from classical geodetic measurement. Based on this, we use high accurate angle-measure equipment to collect data, use eccentric angle, and eccentricity to process azimuth and elevation which collected by optical theodolite, and this helped to avoid the affection caused by position error to angle accuracy. This can help to increase the angle accuracy of acceptance info-source to ten more times. It is of great value in optical theodolite dynamic accuracy evaluation application.
