【摘要】：靶場(chǎng)現(xiàn)有落點(diǎn)坐標(biāo)測(cè)試設(shè)備大多數(shù)基于地面觀測(cè)平臺(tái),存在通視要求的局限性,無法及時(shí)預(yù)測(cè)落點(diǎn)概略坐標(biāo),且對(duì)于連發(fā)密集型射擊試驗(yàn)無法區(qū)分彈序。針對(duì)該問題,根據(jù)物點(diǎn)與像點(diǎn)的幾何位置關(guān)系,提出了3種將觀測(cè)平臺(tái)設(shè)置為空中的無人機(jī)彈丸落點(diǎn)測(cè)量方法:內(nèi)差法、距離比例法以及求解姿態(tài)角法。介紹了3種算法的基本原理和數(shù)學(xué)模型,然后結(jié)合模擬試驗(yàn)現(xiàn)場(chǎng)的測(cè)試數(shù)據(jù)對(duì)3種方法進(jìn)行了驗(yàn)證,最后計(jì)算出滿足要求所需要的相機(jī)最低技術(shù)指標(biāo)。實(shí)驗(yàn)結(jié)果表明:內(nèi)差法和比例法測(cè)量精度低于3m,求解姿態(tài)角法的精度小于0.3m。
[Abstract]:Most of the existing test equipment of landing point coordinate is based on the ground observation platform, which has the limitation of common view requirement, and it can not predict the general coordinates of landing point in time. And for the continuous firing intensive shooting test can not distinguish the order of the projectile. In order to solve this problem, according to the geometric position relationship between the object point and the image point. This paper presents three methods to measure the impact point of UAV projectiles: the method of inner difference, the method of distance proportion and the method of solving attitude angle. The basic principle and mathematical model of the three algorithms are introduced. Then combined with the test data of the simulation test site, the three methods were verified. The experimental results show that the precision of the internal difference method and the proportional method is less than 3 m, and the precision of the attitude angle method is less than 0.3 m.

【正文快照】： 引言近年來,隨著無人機(jī)技術(shù)的快速發(fā)展,加之成像系統(tǒng)的同軸實(shí)現(xiàn),使無人機(jī)快速測(cè)量彈丸落點(diǎn)坐標(biāo)成為可能。自19世紀(jì)中葉至今,攝影測(cè)量已發(fā)展160余年,作為測(cè)繪學(xué)科的一個(gè)分支,主要用于繪制地形圖[1],用在彈丸落點(diǎn)坐標(biāo)測(cè)試尚屬空白。靶場(chǎng)現(xiàn)有的落點(diǎn)坐標(biāo)測(cè)試設(shè)備大多基于地面觀測(cè)，
