File conversion method and apparatus
First Claim
1. A method for converting an image file or document file into a drawing file comprising,extracting an outline from an image of a subject file to be drafted;
- detecting corner feature points from the image of the subject file to be drafted based on the extracted outline to coordinate the corner feature points into outer edge coordinate information and connecting the detected corner feature points with a line to generate a first image;
removing noise from the first image and detecting one or more elements to coordinate the elements into element coordinate information and generating a second image including the one or more detected elements;
superimposing the noise-removed first image and the second image including the one or more detected elements; and
generating a drawing file for the subject file to be drafted by using the outer edge coordinate information and element coordinate information.

Abstract
The present invention relates to a method for converting an image file or document file into a drawing file including the steps of extracting an outline from an image of a subject file to be drafted; detecting corner feature points from the image of the subject file to be drafted based on the extracted outline to coordinate the corner feature points into outer edge coordinate information and connecting the detected corner feature points with a line to generate a first image; removing the outline from the image of the subject file to be drafted and detecting one or more elements to coordinate the elements into element coordinate information and generating a second image including the one or more detected elements; template matching by superimposing the generated first image and second image; and generating a drawing file for the subject file to be drafted by using the outer edge coordinate information and element coordinate information.

12. An apparatus for converting an image file or document file into a drawing file comprising,
an input unit for receiving a subject file to be drafted; -
an image processing unit for extracting an outline from an image of the subject file to be drafted, detecting corner feature points from the image of the subject file to be drafted based on the extracted outline to coordinate the corner feature points into outer edge coordinate information and connecting the detected corner feature points with a line to generate a first image, removing noise from the first image and detecting one or more elements to coordinate the elements into element coordinate information and generating a second image including the one or more detected elements, superimposing the noise-removed first image and the second image including the one or more detected elements, and then generating a drawing file for the subject file to be drafted by using the outer edge coordinate information and element coordinate information; and a storage unit for storing the generated drawing file.
