| 摘 要： | 利用计算机视觉进行三维点云获取是一种实用方便的三维信息提取方法,在工业检测和三维建模等领域应用广泛.鉴于传统固定相机方法中存在着灵活性差,适用范围小的问题,提出了一种手持单相机的三维点云获取方法.实验结果表明,该方法在室外场景点云获取应用中较传统方法在灵活性方面具有非常明显的优势. |

| Abstract: | Acquiring 3D points cloud using computer vision principle is a practical and convenient way to get three-dimensional information.This technology is widely used in industrial detection,3D modeling,and robot navigation etc.The traditional method needs that the two cameras are fixed thus have bad flexibility and a small visual field.The new method brought up here can fulfill the job with only one camera on condition that the accuracy is relaxed.Empirical data shows that it has a great advantage compared with the traditional one in terms of flexibility. |
