The invention relates to the technical field of three-dimensional geographic information, in particular to an indoor and outdoor integrated modeling method and device. The indoor-outdoor integrated modeling method includes acquiring point cloud data of an indoor space preset with an anchor point, and acquiring the absolute position coordinates of the anchor point as the first position coordinates, according to the point cloud data and the first position coordinates to establish an indoor basic model; obtain a texture picture of the indoor space, and attach the texture picture to the indoor basic model to form an indoor model; obtain an outdoor real-scene image preset with a control point, and obtain the control point The absolute position coordinates are used as the second position coordinates, and an outdoor real scene model is established according to the outdoor real scene image and the second position coordinates; the indoor model and the outdoor real scene model are fused to form an indoor and outdoor integrated model. Compared with the prior art, the indoor and outdoor integrated modeling method and device not only have higher modeling efficiency but also have higher accuracy of the built model.
Description
technical field [0001] The invention relates to the technical field of three-dimensional geographic information, in particular to an indoor and outdoor integrated modeling method and device. Background technique [0002] Digital city is a research hotspot in recent years. Reconstruction of 3D model of buildings is of great significance in construction method research, security monitoring, building restoration, urban planning and design, etc. For indoor and outdoor integrated modeling, at present, 3D laser scanners are usually used to collect indoor and outdoor integrated modeling data, and then 3D modeling is performed based on the collected data. The accuracy of the built model is often not high, and the absolute position of the building Coordinates are not known. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide an indoor and outdoor integrated modeling method and device to solve the above problems. [0004] The indo...
