Panoramic three-dimensional image manufacturing method

Abstract

The invention provides a panoramic three-dimensional image manufacturing method, and in particular relates to the field of image synthesis. According to the panoramic three-dimensional image manufacturing method provided by the embodiment of the invention, by the adoption of an image correction mode, 9 direction cosines of an external azimuth angle element and camera calibration parameters are obtained from spatial three-dimensional encrypted data, pixel points on each original image are subjected to correction according to the width and the height of a pre-acquired standardized image, so that the standardized image is generated, and the inclinations of the original images caused by inclination of a shooting angle can be corrected, therefore, the original images can be perpendicular front view images and can be easily spliced during synthesis of a three-dimensional image; furthermore, coordinates of each standardized image within a bottom surface projection range are determined in a standard coordinate system, so that the superposition degree of the standardized images can be precisely determined, and thus the synthesis of the three-dimensional image is precisely finished, namely the synthesis of the three-dimensional image is finished under a condition that DEM data are not used.

Description

technical field [0001] The invention relates to the field of image synthesis, in particular to a method for making a panoramic stereoscopic image. Background technique [0002] In recent years, 3D stereoscopic vision technology has attracted wide attention, and both stereoscopic display devices and 3D stereoscopic works (3D movies, games, books, sports events) have achieved great development. [0003] However, in the field of photogrammetry, this technology has appeared as early as the end of the 18th century, and has been widely used by photogrammetry workers. In the course of development for hundreds of years, it has been applied to dual image projection mappers, stereo mappers, analytical mappers and even today's digital photogrammetry workstations and digital photogrammetry grids. However, in the current photogrammetry, the stereo vision technology has always been based on the construction of a single stereo model using two aerial photos with a certain degree of overlap...

AI Technical Summary

Problems solved by technology

MVR breaks through the limitation of single-model stereo, and meets the requirements of continuous stereo observation to a certain extent. However, because the stereo model is constructed by artificially introducing parallax from DEM data, the final stereo model can only be an approximation of the real model, and the degree of model approximation depends on The accuracy of DEM data and the method of artificially introducing parallax

This dependence on high-precision DEM data and the approximation to the real scene have limited the practical application of MVR.
