Embodiment 1

[0028] The embodiment is basically as attached figure 1 shown, including:

[0029] The development planning module is used to plan and design the development plan of urban construction;

[0030] The running simulation module is used to deduce the development plan based on the simulation model, and obtain the operation effect of the development plan in the city operation;

[0031] The modeling and rendering module is used to construct a 3D city virtual scene according to the development plan, seamlessly render the 3D city virtual scene in different regions according to the preset angle, and generate a multi-angle 3D map; cut the 3D map to obtain the cut map ; Carry out data encoding and organizational management on the cut map according to the angle, so that the three-dimensional map can be transformed from multiple angles to obtain the rendering effect;

[0032] The scheme evaluation module is used to evaluate the development scheme according to the operation effect and the ...

Embodiment 2

[0045] The only difference from Embodiment 1 is that the modeling and rendering module includes a display unit, which uses dynamic interactive technology to display the rendering effect in an all-round way, so that an immersive and all-round observation of the future city can be carried out. Under the premise of acceptable rendering error and good rendering effect, visually display the physical scene.

Embodiment 3

[0047] The only difference from Embodiment 2 is that the structure of the three-dimensional map is repaired. In this embodiment, the attitude information of pictures such as residential buildings and commercial buildings are obtained in advance according to the development plan of urban construction, for example, the information of various attitudes taken by these pictures; the specific process is as follows: first, the attitude information of these pictures is sparsely reconstructed , to obtain the sparse point cloud and the pose information of the picture; then, save the pose information of the picture, and re-establish a 3D map; then, obtain a snapshot of each picture based on the pose information of the picture, and form a set of picture pairs, that is, in In the reconstructed 3D map, the pose information of the sparsely reconstructed picture is used to construct the position of the camera, and the snapshots in the same pose are obtained through the camera. Each picture and...

Abstract

The invention relates to the technical field of urban planning, in particular to a city operation simulation and overall planning system, which comprises a development planning module used for planning and designing a development scheme of urban construction; an operation simulation module which is used for deducing the development scheme based on the simulation model to obtain the operation effect of the development scheme in urban operation; a modeling rendering module which is used for constructing a three-dimensional city virtual scene according to the development scheme, performing regional seamless rendering according to a preset angle, and generating a multi-angle three-dimensional map; cutting the three-dimensional map to obtain a cut map; and performing data coding and organization management on the cut map according to angles, so that the three-dimensional map is subjected to map transformation at multiple angles, and a rendering effect is obtained; and a scheme evaluation module which is used for evaluating the development scheme according to the operation effect and the rendering result. According to the system, the three-dimensional map can be subjected to map transformation from multiple angles, and the technical problem that a city cannot be observed from multiple directions in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of urban planning, in particular to an urban operation simulation and overall planning system. Background technique [0002] In recent years, 3D simulation cities have become an important means for major cities to show their style. Observing city information from multiple perspectives and presenting three-dimensional, colorful maps to the public, the map display mode of 3D simulation cities has gradually replaced The two-dimensional map is a fixed pattern with simple patterns and insufficient three-dimensional and intuitive information description. City simulation mainly uses database technology, geographic information system technology and virtual reality technology to carry out three-dimensional digital measurement of the existing urban topography and features, obtain three-dimensional structure information and texture information, and form a virtual landscape model through three-dimensional visualization ...
