Abstract

The present invention provides a method, device and system of generating a road orthographic projection image. The method comprises the steps of obtaining the coordinate and posture of an image at the current shooting moment; obtaining the orthographic projection image of a road pavement at the current moment shot by a panorama camera according to the image acquired by the panorama camera; according to the coordinate and posture of the image and the orthographic projection image of the road pavement, embedding the orthographic projection image of the next shooting moment in the orthographic projection image obtained at the previous shooting moment to generate the road orthographic projection image. By the above scheme, the road orthographic projection image is generated in a manner of carrying out the orthographic projection and the image embedment based on a panorama image, the road orthographic projection image can be generated rapidly and conveniently by the method, at the same time, the image production cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of surveying and mapping, in particular to a method, device and system for generating road orthographic projection images. Background technique [0002] Road ortho-projection images are one of the main forms of road navigation data, and are widely used as basic spatial data in the application fields of public security, transportation and other spatial information industries. However, the existing conventional road orthoprojection image acquisition scheme is to use small aircraft or UAVs loaded with surveying and mapping equipment to fly over the planning area, acquire remote sensing image data by means of orthographic projection or oblique projection, and then The processing center uses a ground image processing system to obtain higher-resolution road orthographic projection images through processes such as image filtering, image enhancement, orthorectification, and image stitching. [0003] However...
