【摘要】 在建筑内部的结构稳定性研究中,由于形成的多角度离散网络模型无法形成稳定的拓扑结构,导致传统的三维图像建模只能忽略拍摄角度不同带来的坐标计算误差,以保障稳定的三维模型拓扑结构,导致转换的三维坐标存在失真,三维建模不准确。提出改进离散算法的大型建筑多角度图像三维建模方法,首先对大型建筑的多角度原形进行采集,其次通过分析原始数据点之间的拓扑关系,组建大型建筑的多角度图像离散网络模型。融合于双目立体视觉成像原理,依据不同位置拍摄的大型建筑多角度图像中对应点的图像坐标,计算出不同角度的大型建筑在三维空间中所对应点的三维坐标,实现了大型建筑的多角度图像三维稳定建模。仿真结果证明,改进离散算法的大型建筑的多角度图像三维建模准确率高,实用性强。

【Abstract】 In the study of the structural stability of the building interior,because the formation of multi-angle discrete network model cannot form a stable topological structure,causing that the traditional 3D image modeling can only neglect the coordinates calculation error caused by the difference of shooting angle,to ensure the stable topological structure of 3D model,which will result in the distortion of 3D coordinate and inaccurate 3D modeling.In the paper,a 3D modeling method for multi-angle image of huge buildings was proposed based on improved discrete algorithm.Firstly,the multi-angle prototype of huge buildings was collected.Secondly,by analyzing the topological relationship between the original data points,the discrete network model for multi-angle image of huge buildings was established.To integrate in the principle of binocular stereoscopic vision imaging,according to the image coordinates of corresponding points in multi-angle image of huge buildings taken from different positions,the 3D coordinate of corresponding points of the huge buildings in different angles in 3D space can be calculated,to implement the 3D stable modeling of multi-angle image of the huge buildings.The simulation results prove that the accuracy of 3D modeling of huge building’s multi angle image based on improved discrete algorithm is high,and the practicality is strong.
