倾斜摄影在矿区工程测量的关键技术研究

Study on Key Technology of Oblique Photography in Engineering Survey in Mining Area

摘要:

矿区工程测量已从传统的人工测绘转变到无人机航空摄影测绘，既节省人力，又提高了效率和精度。随着科技的发展，无人机航空测绘也逐渐从垂直摄影发展到倾斜摄影。本文根据矿区工程测量的特点，阐述了倾斜摄影像控点布设和航测飞行方案的关键技术要点，列举出了多种像控点布设方案，并加以对比，最终通过实际量测，得到了多组有效地验证。得出结论为在矿区按照测绘区角部、边部点组均匀布设及中心少量布设为最佳方案，为矿区的工程测量、生产运营、监督管理等方面提供科学依据。

Abstract:

Engineering survey in mining area has changed from traditional artificial mapping to aerial photography mapping of drones. It not only saves manpower, but also improves efficiency and precision. Accompanying with the development of technology, drone aerial surveying and mapping has gradually developed from vertical photography to oblique photography. According to the characteristics of engineering survey in the mining area, key technical points of the layout of tilt photography image control points and the aerial survey flight scheme, lists and compares various image control point layout schemes have been introduced, and finally obtains effective verification by multiple groups through actual measurement. It is concluded that the best scheme is to uniformly arrange the corner and edge point groups and a small number of center points in the mining area according to the mapping area. It will provide scientific basis for engineering survey, production operation, supervision and management of the mining area.
