摘　　要：随着大数据、人工智能、数字孪生、元宇宙等对室内精细化三维重建的需求越来越多,快速、高效的三维重建成为了研究热点。视觉即时定位与地图构建(SLAM)作为高效的室内三维重建技术得到了广泛关注与快速发展。本文利用3D空间像机+视觉SLAM技术完成了室内2 500 m^(2)的快速三维重建与应用展示。最终结果表明,采用该方案能够快速完成三维结构重建,且三维成果具有丰富纹理信息,精度误差可以控制在厘米级。该方案作为室内三维重建技术的有效补充,可广泛应用于实景三维中国建设中部件级三维模型重建。Fast and efficient 3D reconstruction has become a research hotspot with the increasing demand for indoor refined 3D reconstruction from big data,artificial intelligence,digital twin,and metaverse.Visual SLAM has become focus and get rapid development as an efficient indoor 3D reconstruction technology.The 3D space camera and visual SLAM technology has been used in this paper to rapidly reconstruct and display the indoor 3D objects of an area of 2,500 m^(2).The results show that the method mentioned above can be used to quickly reconstruct 3D structure,and obtain the 3D results with rich texture information,and the data accuracy can be in centimeter.This method,as an effective supplement to indoor 3D reconstruction technology,can be widely used in building 3D realistic geospatial scene in China.
