【摘要】：針對目前已有的無人機攝影測量系統(tǒng)存在的精度不高、依賴起降場地、續(xù)航能力差等問題,設(shè)計并實現(xiàn)了無人直升機攝影測量系統(tǒng),該系統(tǒng)將Phase相機、Applanix POS設(shè)備集成在3軸穩(wěn)定對地觀測吊艙內(nèi),具有垂直起降、載荷量大、續(xù)航能力強、測量精度高等優(yōu)勢。在嵩山遙感定標場開展了測試飛行,結(jié)果表明:系統(tǒng)直接地理定位精度較高,可用于應(yīng)急測圖;在少量控制點參與下,系統(tǒng)定位精度遠優(yōu)于1∶500測圖要求,可用于大比例尺測圖,具有重要的推廣應(yīng)用價值。
[Abstract]:In view of the problems existing in the existing UAV photogrammetry system, such as low accuracy, dependence on take-off and landing sites, poor endurance ability and so on, an unmanned helicopter photogrammetry system is designed and implemented, which uses Phase camera. The Applanix POS equipment is integrated in the 3-axis stable ground observation pod, which has the advantages of vertical take-off and landing, large load, strong endurance and high measurement accuracy. The test flight is carried out in Songshan remote sensing calibration field. The results show that the direct geographical positioning accuracy of the system is high and can be used for emergency mapping. With the participation of a small number of control points, the positioning accuracy of the system is much better than that of 1 / 500 mapping, which can be used in large scale mapping, and has important popularization and application value.
