Method for constructing virtual streetscape map

Abstract

A method for constructing a virtual street view map disclosed by the present invention includes the following steps: step S1, constructing a three-dimensional model of the target space; step S2, constructing an electronic map of the target space; step S3, making a generation sequence based on the three-dimensional model of the target space A virtualized three-dimensional panoramic image set with continuous front and back information and coordinate information; step S4, associating the virtual three-dimensional panoramic image set in step S3 with the electronic map in step S2, and publishing it on the web based on the browser. The present invention realizes a new method for generating a virtual street view map, realizes the cross-platform and cross-terminal barrier-free transmission of three-dimensional model data, and greatly improves the information dissemination and user arrival rate of the target space.

Description

technical field [0001] The invention relates to a method for constructing a virtual street view map based on three-dimensional modeling technology and street view map technology. Background technique [0002] Street view map is a real map service that combines electronic map technology and 3D panorama technology. The street view car takes pictures at certain distances (usually 10 meters) during driving to obtain a 3D panoramic image centered on the shooting point, and at the same time records the GPS information at the time of collection, and calculates each panorama through the time stamp relationship According to the coordinate information, the three-dimensional panorama is integrated into the electronic map to provide street view map service for visitors to browse. The three-dimensional representation of the street view map forms a strong contrast with the 2D flat map, making the original boring map more vivid, more readable and entertaining. Users can browse high-defin...

Problems solved by technology

For the non-existent target space, or the scene in the planning and implementation process, it is mainly constructed through 3D modeling technology, and then displayed through special 3D display software. However, due to network security and user habits, it is necessary to download plug-ins for data reading. The method adopted is less and less accepted by users, so that the fine and exquisite modeling results produced by spending huge sums of money cannot enter the user's field of vision due to the bottleneck of display technology. Therefore, a new technical means and display are needed. method to solve the display problem of 3D modeling data
