水库建设无人机真正射影像制作与关键技术分析

Analysis of Real Shooting Image and Key Technology of UAV for Reservoir Construction

目前正射影像数据广泛应用于水利水电工程建设项目中,也是最基础的辅助规划设计航测产品之一。由于城市的快速发展,水利工程项目区域出现许多高架桥、高层居民楼等高落差地物,然而大多数的影像成果仍是没有经过严格正射纠正的传统正射影像,不可避免地出现地物错位、遮挡、扭曲、变形等问题,严重影响影像判读。基于正射纠正原理探讨与分析真正射影像制作的关键技术,并结合水库项目实现真正射影像地生产,对测绘生产具有一定的参考作用。

At present,orthophoto data is widely used in water conservancy and hydropower construction projects,and it is also one of the most basic aerial survey products that assist planning and design.Due to the rapid development of the city,there are many high-drop features such as viaducts and high-rise residential buildings in the water conservancy project area.However,most of the image results are still traditional orthophotos that have not been strictly orthorectified,and the dislocation of features will inevitably occur.,Occlusion,distortion,deformation,etc.,which seriously affect image interpretation.Based on the principle of ortho-rectification,the key technology of real radio image production is discussed and analyzed,combined with the reservoir project to realize real radio image production,which has a certain reference effect on surveying and mapping production.
