Color segmentation based regulatory plan drawing automatic vectorization method and system

Abstract

The present invention provides a color segmentation based regulatory plan drawing automatic vectorization method and system. The method comprises the following steps: 1) establishing a pixel database, and classifying HSV color spaces into a plurality types according to different tones, saturation and brightness; 2) converting a to-be-processed image into an HSV color space; 3) matching each pixel point in the to-be-processed image of the HSV color space with a type in a database, so as to obtain a segmented image; 4) loading the image by means of OpenCv, performing gray-scale image conversion on the image, binarizing the image, and performing via extraction on the image, so as to obtain a vector coordinate set of each type; and 5) converting the vector coordinate set in the above step into a vector drawing. The beneficial effects of the method and system provided by the present invention are as follows: due to adoption of the method, the drawing can be rapidly analyzed, so as to complete the whole vector drawing conversion process, which greatly reduces the workload of original manual inputting.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to an automatic vectorization method and system for control drawings based on color segmentation. Background technique [0002] When doing work related to power planning, it is often necessary to make space load forecasts for the planned plots. In most cases, operators cannot obtain standard vector drawings from the power department, but can only get pictures in image formats (JPG, BMP, PNG) Drawings, in order to make accurate predictions, it is necessary for the staff to personally draw the control drawings in the image format into CAD or other systems, which greatly increases the workload, which requires a method that can quickly convert the image format and system. Contents of the invention [0003] In view of this, the present invention aims to propose an automatic vectorization method and system for control drawing based on color segmentation. [0004] Technical ...
