【摘要】：提出并實(shí)現(xiàn)了一種基于無(wú)人機(jī)的大場(chǎng)景序列圖像自動(dòng)采集和三維重建方法,實(shí)現(xiàn)了大范圍場(chǎng)景全自動(dòng)圖像數(shù)據(jù)采集和三維建模。首先設(shè)計(jì)實(shí)現(xiàn)無(wú)人機(jī)自動(dòng)控制地面站和基于Cortex-A17的無(wú)人機(jī)控制模塊,其次在地面站人工點(diǎn)選設(shè)計(jì)航線和拍攝位置,并自動(dòng)控制飛行和拍攝過(guò)程,實(shí)時(shí)將序列圖像回傳地面站,最后地面站應(yīng)用SFM方法實(shí)時(shí)自動(dòng)重建大場(chǎng)景三維模型。實(shí)驗(yàn)結(jié)果表明,相對(duì)于人工控制方法,文中方法能夠?qū)崿F(xiàn)無(wú)人機(jī)飛行和拍攝過(guò)程自動(dòng)控制,同時(shí)提高拍攝穩(wěn)定性,降低基于無(wú)人機(jī)的大場(chǎng)景三維建模難度,提高建模效果。
[Abstract]:An automatic image acquisition and 3D reconstruction method for large scene sequences based on UAV is proposed and implemented. Automatic scene image data acquisition and 3D modeling are realized. Firstly, the UAV automatic control ground station and UAV control module based on Cortex-A17 are designed and implemented. Secondly, the design route and shooting location are manually selected at the ground station, and the flight and shooting process are automatically controlled, and the sequence images are transmitted back to the ground station in real time. Finally, the SFM method is used to reconstruct the 3D model of large scale scene automatically. The experimental results show that compared with the manual control method, the proposed method can realize the automatic control of UAV flight and shooting process. At the same time, it improves the shooting stability, reduces the difficulty of 3D modeling of large scene based on UAV, and improves the modeling effect.

【正文快照】： 隨著各個(gè)行業(yè)信息化程度的提高,使用三維模型準(zhǔn)確記錄現(xiàn)實(shí)世界大規(guī)模場(chǎng)景表面幾何和紋理形態(tài)的需求日趨迫切。傳統(tǒng)的人工測(cè)量拍照并數(shù)字化建模的方法,由于費(fèi)時(shí)費(fèi)力并且準(zhǔn)確性,已經(jīng)很少被應(yīng)用在大場(chǎng)景三維建模中;20世紀(jì)80年代以來(lái),應(yīng)用基于激光或相位技術(shù)的非接觸式掃描設(shè)備對(duì)
