Abstract

The invention discloses a processing method and device for a three-dimensional map. The processing method comprises the following steps of obtaining multiple groups of image data obtained by shooting a target area, wherein resolutions of images represented by each group of image data in the multiple groups of image data are different, and each group of image data is used for representing a plurality of images; obtaining image description information of each image represented by multiple groups of image data according to a merging result of multiple groups of image data; and generating the three-dimensional map of the target area based on the image description information of each image and the multiple groups of image data, wherein the three-dimensional map of the target area includes map information corresponding to the images with the different resolutions, which are represented by multiple groups of image data. Through the method and the device, a problem that the existing technology cannot give consideration to both modelling range and modelling precision of a three-dimensional electronic map is solved, and an effect of large-scale high-precision modelling is realized.

Description

technical field [0001] The present invention relates to the field of map data processing, in particular, to a method and device for processing a three-dimensional map. Background technique [0002] The three-dimensional electronic map is a three-dimensional simulation and abstract description of the real world according to a certain proportion, which is a digital representation of a specific area. application prospects. The traditional way of constructing a 3D map is to obtain the 3D scene features by taking photos on the basis of the established 3D city vector model, and perform one-to-one manual mapping to finally form a 3D map of the area. The period is long, and the model effect is not realistic. [0003] In order to reduce the manual workload, a real 3D modeling technology based on oblique photographic images is proposed in the prior art. This technology can be applied to big cities, tourist attractions and single 3D modeling, but the prior art mainly uses Aerial ima...
