| 摘 要： | 针对传统三维重建方法计算复杂度高的问题，提出一种基于虚拟高度投影线的三维重建方法。该方法将场景栅格化，在栅格中引入虚拟高度线，把虚拟高度线投影到二维图像上形成投影线，并在投影线上找到对应点得到三维场景信息，以反映场景的真实信息。分析引起误差的主要来源，针对误差来源结合摄像机内外参数提出补偿方法。通过实验验证了该方法的有效性。

| Abstract: | Aiming at the problem of 3D reconstruction method high computation complexity,3D reconstruction method based on Virtual Height Projection Line(VHPL) is proposed.Scene is divided into grids where Virtual Height Lines(VHLs) are introduced,and each projection lines(PL),generated by projecting VHL into 2D image,whose correspondence is found to obtain the 3D data,the proposed method can express the scene basically.The error is analyzed,and the compensation is proposed combined with the intrinsic and extrinsic camera parameters.Experiments show the validity of the method. |
