This application relates to a method for quickly constructing an urban road map, comprising: obtaining the collected location data of each road in a local area; performing plane conversion on the location data of each road to obtain the corresponding plane coordinates of each road; and The plane coordinates of the roads are corrected to obtain the corrected coordinates of each road; the local area is rasterized to obtain a local area grid map; based on the local area grid map, combined with the corrected coordinates of each road to construct the initial grid of the local area map, and analyze the coordinate range of the local area, and finally obtain the road map of the local area after zooming or restoring the initial grid map according to the accuracy requirements of the currently constructed map. It only needs to collect and acquire the location data of each road in the local area, and only need to carry out the corresponding plane conversion and correction to process the data, which effectively speeds up the construction speed of the road map, thus greatly shortening the time required for the road map. build cycle.
Description
technical field [0001] The present application relates to the technical field of map surveying and mapping, and in particular, to a method, device and device for rapidly constructing an urban road map. Background technique [0002] The complex and changeable road conditions have greatly interfered with the operation efficiency of the urban road network. In the face of long-term or short-term changes in road conditions, if we can optimize and adjust from the overall perspective of road network operation, traffic will be greatly improved. Digitalization is an effective way to improve road network management. In the related art, existing urban road map construction methods can obtain road network maps through field surveying and mapping based on surveying and mapping instruments and automatic generation based on remote sensing images. However, obtaining road network maps through field surveying and mapping based on surveying and mapping instruments and automatic generation bas...
