光电准直经纬仪的测量控制系统

测量控制系统是光电自准直经纬仪的核心部分,它直接影响了经纬仪测量失准角的精度.本文介绍了一种用于地面瞄准系统的经纬仪测量控制系统,该系统采用CCD作为光电传感器,通过一系列的信号处理及测量来求出图象落在CCD靶面的中心点,根据设定的数学模型求出失准角,从而完成自准直经纬仪系统的自动测出失准角的功能.

THE MEASURING AND CONTROLLING SYSTEM OF PHOTOELECTRICITY AND COLLIMATION THEODOLITE

The measuring and controlling system is the center of photoelectricity and collimation theodolite.It effects the measuring precision of error angle for theodolite.The text introduces a kind of measuring and controlling system of theodolite for ground collimation.This system adopts CCD as photoelectric sensor.By using a series of the signal disposal and measurement it can measure the center point which the image drops at the target surface of CCD.According to the mathematics model,the computer can work out the error angle and thus complete the function of measuring the error angle automatically for collimation theodolite.
