摘要
智能化时代的到来促进了计算机视觉技术的发展,在计算机辅助进行几何设计、医学诊断、内容识别等领域的应用需求下,针对获取三维点云数据的关注与日俱增。近年来,已经可以通过简易的双目相机来恢复出较为完整的三维点云,但大多数研究针对的都是近距离室内目标,针对远距离室外场景方面的研究较少。提出了一种基于双目视觉的远距离目标实时三维点云成像技术,这种方法通过与摄影测量技术相结合,为实时获取远距离目标物的三维点云提供了一种低成本、高效率的有效途径。实现了硬件系统的数据采集,设计了软件系统对两台相机进行同步控制,并对远距离目标进行了成像测试实验。实验结果表明该系统能对80~90 m处目标实时三维点云成像,验证了所设计的硬件与软件系统的正确性与有效性。
The advent of the intelligent era has promoted the development of computer vision technology.With the application of computer-aided geometric design,medical diagnosis,content recognition and other fields,the focus on acquiring 3 D point cloud data is increasing.In recent years,it has been possible to recover a relatively complete 3 D point cloud through a simple binocular camera,but most of the research is aimed at close-range indoor targets,and there are few studies on long-distance outdoor scenes.This paper proposes a real-time 3 D point cloud imaging technology for long-distance targets based on binocular vision.This method,combined with photogrammetry technology,provides a low-cost,high-efficiency and effective way to obtain 3 D point clouds of distant targets in real time.This paper realizes a hardware system for data acquisition,designs a software system to synchronize the two cameras,and performs the imaging test of long-distance target.The experimental results show that the system can realize real-time 3 D point cloud imaging of targets at 80~90 m,which verifies the correctness and effectiveness of the designed hardware and software system.
