摘要
探寻能满足需要并低成本高效快速构建地物三维逼真场景的方法是当前研究的一个热点。利用低价大疆无人机获取地表、地物影像与价格适中的Pix4D软件结合来快速构建地物三维模型是一种方法。该方法虽采用传统以摄影获取地表数据的方式,但手段和手续方便简单,数据采集工作效率高;影像数据处理用Pix4D软件基于点云数据三维建模,有操作方便、高效快速、自动化程度高等特点。用不同的实验建模方案、数据与建模参数,对最终建成的模型和结果有影响,经对结果进行精度评价,表明该方法能满足要求,可行、可用。
It is a hot research area to explore the method of constructing three - dimensional realistic scene with low cost and high efficiency. It is a kind of method to combine the low - cost DJI UAVs to get the surface and ground objects image and the Pix4D software with the right price to construct the three - dimensional model. Although the method adopts the traditional approach to obtain surface data by photography, the means and pro- cedures are simple and convenient, the data collection is work efficient. Image data processing with Pix4D soft- ware based on point cloud data building three - dimensional models is easy to operate, efficient and fast, high degree of automation. The different experimental modeling schemes, modeling data, and modeling parameters can influence the resulting model and results. The accuracy evaluation of the results show that the method can meet the general requirements and can be used.
