摘要
黄河三峡地势较为险要,传统勘测手段,不仅数据获取困难,而且难以从三维直观和真实印象方面详细描述,在一定程度上制约着景区的预先宣传和景区影响.提出利用无人机倾斜摄影技术的黄河三峡三维重建方法,通过无人机倾斜摄影技术获取景区序列影像,进行景区三维重建.选取河南济源黄河三峡景区孤山崖周边区域进行试验,结果表明,重建的三维模型可全面表达景区整体形态和保持局部细节特征,而且具备高效低成本等特点,在黄河三峡三维重建和三维可视化宣传方面具有一定的指导意义.
Because of the dangerous ten＇ain of the Three Gorge of Yellow River, the traditional survey method is difficult to acquire and describe the three dimensional visually and truly impressions of scenic spots, and to a certain extent, it restricts the advance propaganda and the influence of scenic spots. A three-dimensional reconstruction method of scenic area based on UAV oblique camera technique is put forward. Three Gorge of Yellow River in Jiyuan City of Henan Province is selected for experiment, he results show that the reconstructed 3D model can not only fully express the overall shape of the digital scenic spot but also maintain local features, with the characteristics of high efficiency and low cost. It has important significance in the area of 3D reconstruction and three-dimensional visual publicity in digital scenic spots.
