| 摘 要： | 以西宁市某区域的城镇数据为例,首先采用飞马D200无人机搭载的SONY ILCE-6000相机采集影像数据,利用infor软件的MATCH-AT模块与Context Capture 结合构建实景三维模型．然后,通过多视倾斜影像数据的两次平差方法实现大区域多视倾斜影像数据的整体平差;结合多视倾斜影像的密集匹配、纹理自动映射算法,构建高精度的实景三维模型．最后,通过实验对空三精度、三维模型精度进行统计,基本满足1∶500大比例尺测图要求,为高精度三维模型的构建提供一种思路.

| Abstract: | Taking the urban data of a certain area in Xining as an example, firstly, the Sony ilce-6000 camera carried by the Pegasus D200 UAV is used to collect image data, and the match-at module of infor software is combined with context capture to build a real 3D model. Then, the overall adjustment of large area multi view tilt image data is realized by two adjustment methods of multi view tilt image data. Combined with the dense matching and texture automatic mapping algorithm of multi view tilt image, a high-precision real 3D model is constructed. Finally, through the experiment, the spatial three-dimensional accuracy and three-dimensional model accuracy statistics basically meet the requirements of 1:500 large-scale mapping, which provides a way of thinking for? the construction of high-precision three-dimensional model. |
