Description
A SYSTEM USED FOR IDENTIFYING GEO-ASSETS
Technical Field
The present invention relates to a system which enables to vectorize zoning plans and/or cadastral plans that are converted into raster format and to present these as data comprising coordinate, particularly in land surveying and planning fields.
Background of the Invention
Plans and map bases are one of the most important components of smart cities. However, digitization of non-numeric data is one of the major obstacles for smart cities. Today, semi-automatic algorithms with manual or pixel tracking are used in order to digitize paper sheets or plans. Vectorization of data -such as usually zoning plan, cadastral plan- which are provided on paper or converted into raster format upon being scanned, manually or semi-automatically is a transaction requiring time and labour. At the same time, vectorization transaction is a quite error-prone process. Data which are processed by means of semi-automatic methods comprise only point, line, field information apart from plan or cadastral field information and then definitions of these interim outputs such as block, plot, residential area are carried out by operators. In addition, the precision of human eye to distinguish is 0,2 mm. And this leads to the fact that it takes about two days to make a plan manually by a human and it causes defects in the precision of a plan based on the fact that the person carrying out the plan gets tired as well. Therefore, today there is need for a solution which enables to perform transaction of digitizing zoning plans and/or cadastral plans -that are converted into raster format- automatically independently of human, in land surveying and planning fields.
The Chinese patent document no. CN111626947A, an application in the state of the art, discloses a system and method for vectorising map contents in an image format on a network, semi-automatically by using deep learning. The said invention provides a map vectorization sample enhancement method and system based on a generative adversarial network and it comprises the following steps: SI, preprocessing an image map; s2, constructing a generative adversarial network and training a sample generation model; s3, calibrating a self-sample; s4, generating a sample substrate; and s5, carrying out sample combination enhancement. According to the invention, the lightweight sample set of the self data of the image map is manufactured; the space of the effective sample set is greatly expanded by constructing a deep learning model of the generative adversarial network, so that the space can meet the data volume requirement of a deep learning training image vectorization model. In the disclosed invention, compared with the traditional process of realizing vectorization of the image map manually/semi-automatically, the method provided by the invention only needs to plot a small amount of initial samples manually and subsequently generates massive training samples meeting requirements in a full-automatic manner, thereby it provides powerful technical support for research and application of vectorization of the image map.
