Reality testing method for design drawing

Abstract

The invention relates to the field of computer image processing and particularly relates to a reality testing method for a design drawing. The reality testing method comprises the following steps of: carrying out reality longitude-latitude coordinate mapping on the design drawing to enable a picture coordinate of each pixel point on the design drawing to be corresponded to a reality longitude-latitude coordinate, and enabling the design drawing subjected to the coordinate mapping to be corresponded to the real earth; or covering the design drawing subjected to the coordinate mapping on a map of the real earth, wherein the longitude-latitude coordinate of the design drawing is corresponding to that of the real earth. According to the reality testing method for the design drawing, the corresponding between the design drawing and the real earth is realized, so that the design drawing can be viewed based on the map of the real earth and subjected to reality testing, and users can conveniently carry out various relevant outdoor earth applications to reduce errors and fast consulting offset according to the design drawing.

Description

technical field [0001] The invention relates to the field of computer image processing, in particular to a real verification method for design drawings. Background technique [0002] At present, in road design, urban planning, project site selection, environmental design, water conservancy, electric power, land use, geological survey, mine construction, and applications involving outdoor land design such as agriculture, forestry, animal husbandry and fishery, the design drawing is generally first carried out. Drawing, during the drawing process of the design drawing, each pixel corresponds to a picture coordinate, and in reality it also corresponds to a geodetic coordinate. When it is necessary to match the design drawings with the current situation, there are usually the following methods: 1. Identify the corresponding terrain and landforms by holding the drawings; 2. The method of holding the design drawings with the left hand GPS (GPS) and the right hand to carry out real...

AI Technical Summary

Problems solved by technology

The error of the first method is too large and may even be unrecognizable due to the similarity of topography; the second method is slow and inefficient; the third method is the most accurate method as a surveying profession, but the slowest and costly Most time consuming and usually only used during the construction phase

However, there is still no real-time verification method for design drawings, which is convenient for users to perform various corresponding verifications on outdoor land application error reduction and quick reference based on design drawings.
