一种基于非量测相机图像的三维模型快速重建方法研究

摘要

Aiming at the problem of high data acquisition cost,difficulty and long modeling period in three-di-mensional model construction,a method based on Agisoft Photoscan software is proposed to construct three-di-mensional model using non-measurement camera digital image.Using Agisoft Photoscan software to align two-dimensional image,calculate camera attitude and target three-dimensional space position information,generate target surface dense point cloud data,build object three-dimensional model on the basis of point cloud data, and evaluate dense point cloud precision with three-dimensional laser scanning data as benchmark.Experi-mental results show that this method can quickly establish a high precision three-dimensional model,less in-vestment and high efficiency,so as to better apply to the relevant areas of expertise.%针对三维模型构建时数据获取成本高、难度大、建模周期长的问题,提出一种基于Agisoft PhotoScan软件,使用非量测相机数字图像构建三维模型的方法.利用Agisoft PhotoScan软件将二维图像对齐,计算出相机姿态及目标物三维空间位置信息,生成目标物表面密集点云数据,在点云数据基础上构建物体三维模型,并以三维激光扫描数据为基准评价密集点云精度.实验结果证明,该方法可以快速建立较高精度的三维模型,投入少且效率高,从而更好地应用于相关专业领域.
