基于倾斜摄影建筑模型的采集精度改进与评估

研究了基于倾斜摄影建筑模型的采集以及提高精度的优化算法。针对已有的建筑模型采集方法无法做到很好的精度控制，建筑物边线采集方式单一，获取的边线未经过算法处理的情况，提出了约束条件的建筑边线采集方法，并在此方法基础上通过建筑边线和墙体关系开展优化建筑边线精度的算法研究，即利用给定的采集方法和优化算法。使用该采集方法获取建筑立面线粗图，并将这些数据统一批量优化，进一步从采集阶段和优化阶段有效提高立面线数据的精度。

Improvement and evaluation of building model acquisition accuracy based on oblique photography model

This paper studies the acquisition of building models based on inclined photography and the optimization algorithm to improve the accuracy. The existing building model acquisition methods cannot achieve good precision control, the building edge acquisition method is single, the acquired edge is not processed by algorithm. In view of this reason, a method of building edge line acquisition with constraint conditions is proposed and the algorithm research of building edge line precision is calculated based on the relationship between building edge line and wall. That is, with the given collection method and optimization algorithm, the acquisition method is firstly used to obtain the thick elevation line map of the building, and then these data are unified and optimized in batches. The optimization algorithm of acquisition method can effectively improve the accuracy of elevation line data from the acquisition stage and optimization stage respectively.
