Automatic generation method and system for cultural relic building graphs and storage medium

Abstract

The invention discloses an automatic generation method and system for cultural relic building graphs and a storage medium, and a storage medium. The method comprises the steps: recognizing a pluralityof boundary points forming a color edge line in a three-dimensional orthographic image corresponding to a cultural relic building; fitting all the boundary points into a uniform boundary line; repeatedly identifying the edge lines to obtain a plurality of uniform boundary lines; and combining the plurality of fitted boundary lines to generate two-dimensional graphs required by archiving culturalrelic buildings. Three-dimensional orthographic images of the cultural relic buildings is converted into the two-dimensional vector line graph through the automatic identification software, the derived vector line graph is continuous and clear in line shape, the drawing specification is combined, and layers can be distinguished through different line shapes and the density of lines; compared witha drawing displayed through manual drawing, details are more complete, the line type is smoother, and corner angles are prevented from being stiff; moreover, automatic generation of cultural relic building patterns provides a convenient technology for large-scale development of existing cultural relic archiving requirements, and provides early-stage achievements for other related researches.

Description

technical field [0001] The invention relates to the field of image recognition processing, and more specifically, to a method, system and storage medium for automatically generating graphics of cultural relics and buildings. Background technique [0002] At present, the storage and archiving technology for the overall and partial basic data of cultural relics buildings is relatively common, and this work is a necessary condition to ensure the smooth development of subsequent cultural relics protection work. At present, the three views (plan, elevation, and section) of cultural relics protection projects will still be the most commonly used and most important drawings and materials for the protection and repair of cultural relics for a period of time, and they are necessary for archiving. The three views need to be obtained on the basis of surveying and mapping. At present, the main test method is to use traditional tools such as rulers and tape measures, total stations, lase...
