    摘要:

    傳統的無(wú)人機傾斜攝影測量測量數據有效率低,得到的攝影圖片清晰度差。為了解決上述問(wèn)題,基于自適應末端滑膜控制研究了一種新的無(wú)人機傾斜攝影測量技術(shù),利用垂直影像攝影,將數據進(jìn)行初步收集追蹤,并對傾斜攝影圖像進(jìn)行記錄,結合空中三角測量方法,加強數據自身主導性,同時(shí)為無(wú)人機監測系統提供較好的數據來(lái)源,強化系統內部數據聯(lián)合功能,在多視影像聯(lián)合的過(guò)程中注意充分考慮影像間的遮擋關(guān)系及遮蔽條件,在經(jīng)過(guò)對影像數據的聯(lián)合收集后,對無(wú)人機傾斜攝影數據進(jìn)行數據匹配操作,提升數據的整合性,并通過(guò)數據整理加強攝影影像的可操作性,利用無(wú)人機作為影像傳輸主要載體,進(jìn)一步加強對傾斜影像的監測,確定影像空間位置,在數據集中的過(guò)程中加大滑膜控制,并經(jīng)過(guò)控制點(diǎn)坐標及連接線(xiàn)方位確定輔助數據的具體位置。實(shí)驗結果表明,基于自適應末端滑膜控制的無(wú)人機傾斜攝影測量技術(shù)能夠得到更加清晰的攝影圖片,測量數據的有效率提高了25.21%。

    Abstract:

    Traditional UAV tilt photogrammetry measurement data has low efficiency, and the obtained photographic pictures have poor sharpness. In order to solve the above problem, a new UAV tilt photogrammetry technology was researched based on adaptive end-sliding film control. Using vertical image photography, data was initially collected and tracked, and the tilt photo images were recorded, combined with aerial triangulation. Method, to strengthen the dominance of the data itself, at the same time provide a better data source for the drone monitoring system, strengthen the system's internal data joint function, and pay attention to fully considering the occlusion relationship and occlusion conditions between the images in the process of multi-view image joint. After the joint collection of image data, data matching operations are performed on the tilted photographic data of the drone to improve the integration of the data, and the operability of the photographic image is enhanced through data collation. The drone is used as the main carrier of image transmission to further Strengthen the monitoring of oblique images, determine the image spatial position, increase the synovial control during the data concentration process, and determine the specific position of the auxiliary data through the coordinates of the control points and the orientation of the connecting lines. The experimental results show that the UAV tilt photogrammetry technology based on adaptive end-sliding film control can obtain clearer photographs, and the efficiency of the measurement data is increased by 25.21%.
