Abstract: We focus on 3D object reconstruction from uncalibrated images and put forward a metric approach to recover the object based on slicing planes by homography transformation.Based on the constraints of silhouette and the scene,a set of hypothetical planes are done to intersect the reconstructed object to obtain every slicing plane of the reconstructed object by homography transformation and recover it to 3D.Moreover,we calculate the reconstructed object height by reference height.This approach requires no camera calibration,the estimation of the fundamental matrix or feature matches.The experimental show results that the approach is much validated,which could be applied to regular or non-regular 3D object reconstruction.
