Method for making building effect drawing in real environment

Abstract

The invention is to provide a method for making a building effect drawing in a real environment. The method includes the following steps that 1, fixed point panoramic shooting is conducted on a target region, original images are obtained and the initial coordinates of shooting points are obtained; 2, panoramic stitching is conducted in the original images, and a panorama image in the target region is obtained; 3, one or more images are selected from the original images, a camera parameter corresponding to each image is obtained, control points are selected, the pixel coordinate and the space coordinate of the corresponding control point in each image are obtained, and the actual coordinate of each shooting point and shooting actual angle are calculated; 4, artificial three-dimensional modeling is conducted on a to-be-projected building to obtain a building three-dimensional model; 5, rendering is conducted on the building three-dimensional model to obtain a rendering model; 6, row alignment and fusion is conducted on the rendering model and the panorama image, and the building effect drawing is obtained. According to the method, the defect that a traditional rendering effect drawing is single and not real is overcome, and the method has the advantages of being visual, accurate and high in efficiency.

Description

technical field [0001] The invention relates to the field of surveying and mapping image processing, in particular to a method for making architectural renderings in a real environment. Background technique [0002] In the process of urban development, urban planning plays a very important role, controlling and guiding the direction of the entire urban development. At present, the display methods of my country's urban planning schemes mainly include physical models, rendering renderings, 3D animations, etc. These display methods are either relatively expensive or relatively simple, and cannot directly display the relationship between the planning scheme and the surrounding status quo. Planning approval pays more and more attention to the relationship between the planning scheme and the actual status quo, especially when it is related to key areas and key road sections. Many leaders and experts are not limited to traditional scheme rendering renderings when evaluating plannin...
