Indoor Detection Method Based On Dynamic Target Photoelectric Theodolite Angle Measurement Accuracy

Requirement for tracking performance and angle measurement accuracy of photoelectric theodolite constanly improve as the importance of photoelectric theodolite in weapon equipment and space defense system.How to precisely measure tracking performance and angle measurement accuracy of photoelectric theodolite in dooe enviroment becomes an important problem.The method of sinusoidal guidance can not get ideal result because of existing defects in measurement. We study a kind of optical dynamic target which can simulate space moving object by adjusting speed of optical dynamic target.A new goniometric methods is proposed in this paper according to this dynamic target.It is a new high precision method for dynamic testing angle precision measurement in engineering application.According to error theory, the accuracy of testing equipment need higher than the tested photoelectric theodolite 3 times,therefore,a method for real-time accuracy calibration of optical dynamic target is proposed in this paper.The method not only calibrate the stability under no change the real working environment of the optical dynamic target situation ,but also it can achieves 360 degree range inner calibration.This paper also simulate space position of optical dynamic target and photoelectric theodolite with LABVIEW software, angular velocity and angular acceleration of azimuth and pitch obtained eventually.CCD camera has a lot of advantages such as light-weight,small volume,low power dissipation,long-life,high sensitivity and wide dynamic range and so on, in addition,sub-pixel subdivision technology introduced interpretation greatly improve interpretation precision of miss target value. CCD camera has substituted photographic film at present as a new generation photoelectric receiving media,dynamic angel measurement error changed, therefore, this paper analyse it before discussing dynamic measuring angle .Reserching work for this paper have a certain guiding significance for improve precision of dynamic measuring angle of photoelectric theodolite.
