为解决复杂体型建筑物存在拍摄盲区较多,影像采集分辨率差异较大而导致建模效果差的问题,本文提出了一种无人机立体环绕式摄影与精细化建模方法,选用单镜头小型多旋翼无人机,根据复杂建筑物外观形态,设计出立体环绕式的影像采集航线,再将获取影像导入Context Capture软件进行分析和处理并完成模型建立,最后针对三维模型存在纹理缺失及模糊拉花等信息缺失问题,使用DP-Modeler和3ds Max对模型进行联动修饰。以某公园内两相邻建筑物为研究对象,分别采用新方法与传统无人机倾斜摄影方法,从建模效率、模型精度和纹理细节三方面进行对比实验。结果表明,新方法具有建模效率高、精度高和纹理丰富的优点,提升了复杂体型建筑物建模的质量和效率,联动修饰解决了影像采集过程中信息缺失的问题,显著提升模型细节质量。
In order to solve the problem of poor modeling effect caused by many shooting blind areas and large differences in image acquisition resolution in complex buildings, a three-dimensional surround photography and fine modeling method of UAV is proposed. A single lens small multi rotor UAV is selected to design a three-dimensional surround image acquisition route according to the appearance of complex buildings, Then import the acquired image into context capture software for analysis and processing, and complete the model establishment. Finally, aiming at the lack of texture, fuzzy drawing and other information in the three-dimensional model, DP modeler and 3ds Max are used to modify the model. Taking two adjacent buildings in a park as the research object, the new method and the traditional UAV tilt photography method are used to carry out comparative experiments from three aspects: modeling efficiency, model accuracy and texture details. The results show that the new method has the advantages of high modeling efficiency, high precision and rich texture, improves the quality and efficiency of complex building modeling, linkage modification solves the problem of lack of information in the process of image acquisition, and significantly improves the quality of model details.
