| 摘 要： | 提出了一种基于横向切片的地物可量测性三维重构方法,利用平面单应变换和未标定的多视图完成三维重建。通过对重构物体成像进行轮廓约束及场景约束,假设一组平行平面切割重构地物,通过单应变换得到切片的轮廓线构成物体的形状,进而恢复各层轮廓线的三维值,并加入参考高度,求得重构物体的高度。实验证明了此方法对规则与不规则物体的重建均有效,使得整个三维的求解过程具有可测量性。

| 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 came... |
