【摘要】:在現(xiàn)有光電偏差標(biāo)定方法的基礎(chǔ)上,針對海上動態(tài)環(huán)境下多種方法測量及標(biāo)定船載測量設(shè)備光電偏差結(jié)果一致性較差且難以選擇的問題,提出了一種船載測量設(shè)備光電偏差計算及動態(tài)評估方法。該方法利用空間目標(biāo)精軌信息能夠反演計算高精度測元的特性,結(jié)合船載測量設(shè)備的測量數(shù)據(jù)建立測量方程計算光電偏差,以該計算結(jié)果為理論值對多種方法得到的光電偏差進(jìn)行多屬性優(yōu)選,實測數(shù)據(jù)表明能有效解決動態(tài)測量情況下直接標(biāo)定結(jié)果差異較大難以取舍的難題。
[Abstract]:On the basis of the existing calibration methods of photoelectric deviation, aiming at the problem of poor consistency and difficulty in selecting the photoelectric deviation results of various methods for measuring and calibrating shipborne measuring equipment under the dynamic environment at sea, In this paper, a method for calculating photoelectric deviation and dynamic evaluation of ship-borne measuring equipment is presented. In this method, the precision orbit information of space target can be used to invert and calculate the characteristics of high-precision measurement elements, and the measurement equation is established to calculate the photoelectric deviation in combination with the measurement data of shipborne measuring equipment. The calculated results are taken as the theoretical values to optimize the photoelectric deviation obtained by many methods. The measured data show that the problem that the difference of direct calibration results is difficult to choose under dynamic measurement can be effectively solved.
