Abstract

The invention provides a method for splicing characteristic point correction partitions and is used for solving the problem of digital convergence of historical precious drawings in the prior art. The method comprises the following steps of: 2, acquiring first image data, and selecting a characteristic point group of a first area on a first image according to a preset coordinate; 4, correcting each characteristic point in the characteristic point group, and thus forming a second area; and 6, splicing the second area at a position, corresponding to the first area, on a second image. By adoption of the technical scheme of the invention, the problem of the digital convergence of various kinds of paper drawings which are accumulated over the years and include paper geologic maps with different time, different dryness and humidity and different scales can be effectively solved, the paper drawings can be accurately superposed and converged with geologic, geographic and grid vector data, and use requirements of stages such as scanning, designing, construction, running and maintenance on geologic information are met.

Description

technical field [0001] The invention relates to a feature point correction partition splicing method and device. Background technique [0002] With the urban construction, the geological conditions are becoming more and more complex, the cost of land acquisition and demolition is getting higher and higher, and the pressure of site selection for power projects is huge. However, the traditional board-type and decentralized geological data management mode has low work efficiency and low data utilization rate, and is increasingly unsuitable for the development of information technology. Scanning vectorization is to scan the geological information drawings, identify the lines and printed characters in the drawings, and convert them into vector lines and vector characters, so that they can be scaled with the electronic map. Due to the long-term preservation of historical precious drawings, due to folding and extrusion, the deformation of the drawings has been caused, and certain ...
