A Approach to Sudden Occurred Disaster-Scene 3D Fast Reconstruction

In this paper, we propose an approach to Sudden occurred disaster-Scene 3D fast reconstruction based on UAV sequence images. In this method, Harris feature point and SIFT feature vector is used to distill image feature, achieve images matching; quasi-perspective projection model and factorization is employed to calibrate the uncalibrated image sequences automatically; Efficient suboptimal solutions to the optimal triangulation is plied to obtain the coordinate of 3D points; quasi-dense diffusing algorithm is bestowed to make 3D point denseness; bundle adjustment algorithm is betaken to improve the precision of 3D points; Poisson surface reconstruction approach is used to make 3D points gridded. Sudden occurred disasterScene 3D fast reconstruction on this way can provide base geographic environment platform to analysis of disaster and subsequent decision-making of disaster reduction.
