RGB-D相机的三维重建综述

Overview of 3D Reconstruction Based on RGB-D Camera

三维重建是计算机视觉、计算机图像学重要的研究方向之一。三维重建将相机采集的二维图像信息进行计算处理,生成物体的三维立体信息并加以展示。随着移动端传感器的不断集成,尤其是集成了3D深度相机,为场景三维重建提供了深度信息,可直接采用几何关系得到点云数据,加快了重建速度,可实现实时重建。对RGB-D相机在三维重建方面的研究工作进行总结和分析,论述了传感器、重建流程及算法,对三维重建进行了总结及展望。

3D reconstruction has always been one of the important research directions of computer vision and computer graphics.It mainly uses cameras to collect two-dimensional image information of the scene,and calculate and process the two-dimensional image information to generate and display the three-dimensional information of the object.With the continuous integration of mobile sensors,especially the integration of a 3D depth camera,it provides depth information for the 3D reconstruction of the scene,thereby directly obtaining the point cloud data of the scene from the geometric relationship,speeding up the reconstruction,and realizing real-time reconstruction.This article summarizes and analyzes the research work of RGB-D camera in 3D reconstruction,including sensor,reconstruction process and algorithm,and the three-dimensional reconstruction is summarized and prospected.
