Embodiment Construction

[0050] The specific implementation of the electrical component quotation system of the present invention will be described in detail below with reference to implementation examples, but the protection scope of the present invention is not limited to this.

[0051] An image recognition-based quotation method for electrical components of the present invention includes the following steps:

[0052] Step 1: Read the scanned image F of the electrical design drawing 1 , The original grayscale image such as figure 1 Shown

[0053] Step 2: To scan image F 1 Perform tilt correction, specifically:

[0054] Step 2.1: Use the Hough method to detect straight lines and extract the scanned image F 1 Line in the line, get the line set L={l i |i=1,2,...,n}, n represents the number of straight lines, the gray scale image of the straight line image obtained is as figure 2 As shown; since the electrical component quotation sheet uses a form for information layout, the longer straight lines in the image ...

Abstract

The invention relates to an image recognition-based electrical component quotation method, which utilizes image recognition technology to segment electrical design diagram tables, identify component names, and match quotations in databases. The invention automatically realizes image correction to identify electrical component quotations The location of the table, automatically extract the text information in the table, and get the quotation of each electrical component, which reduces the cumbersome manual information input process, and greatly reduces the input error rate caused by manual input information.

Description

Technical field [0001] The invention relates to an electrical component quotation method based on image recognition, in particular to an electrical component quotation method that uses image recognition technology to segment electrical design drawing tables, identify component names, and provide database matching quotations. Background technique [0002] In recent years, with the development of modern technology, the former paper office method is gradually being replaced by "paperless office". Because it is now in a special period of alternating between the old and the new, there is still a lot of paper information that needs to be manually imported into the computer system. The large amount of paper data information and the inevitable error rate of manual input make the automated information collection system very important. Meaning. [0003] In order to solve the problem of automatic paper information extraction, many solutions have been put forward by the academic and industria...
