Abstract


Target is such a device , in its rotary arm with parallel light pipe , driven by the motor rotating arm emitted from the collimator light parallel to simulate the moving target , different motor speeds to simulate different sports goal, and that you can boot theodolite to track the target , so you can pair your TV or infrared tracking system for testing. With optical rotary target detection requirements continue to increase , more and more obvious limitations , but also increasingly unable to meet the different technical indicators theodolite detection needs. This paper describes a high-precision dynamic target detection in real theodolite important role and practical significance. Established target and theodolite relative motion between the mathematical model to derive a high-precision dynamic target motion equation and analyze high-precision dynamic target of three works . High-precision dynamic target mechanical structure, optical structure has been studied in-depth study of the electronic control system . In improving the accuracy of target state proposed low friction effects by repeating control to improve system tracking accuracy , and to achieve a compensation repetitive control PID control to improve tracking accuracy of the simulation .
