Analysis and correction for influence of vehicle platform deformation on measuring errors
The influence of vehicle platform deformation on the measuring errors of a theodolite was analyzed
then the platform deformation was divided into two types of translation and rotation. A numerical simulation was performed to demonstrate that the platform rotation deformation was the main factors to affect the measuring error of the platform.A simulation model of vehicle theodolite between measuring error and rotation deformation was established
and the influence of the target location and rotation deformation on measuring errors was simulated based on the model. Furthermore
the platform angular deviation was measured by a self-collimation measurement system based on Moir fringe and the platform angular rotation was measured by a inclinometer
which then was validated by experiments.Obtained data show that this method can effectively compensate static angle measuring errors come from the deformation of vehicle platform
and can improve the azimuth precision to 103.7and elevation precision to 89.4. It provides a theoretical reference and technical support for the high-precision measurement of vehicle theodolites.
