A method for extracting corner stamp information

Abstract

The invention discloses a corner stamp information extraction method. By calculating the length and width of the rectangular area where the text content of the unique identification object set by the template included in the entity object of the drawing is located, the preliminary scaling ratio M1 of the entity object is initially calculated. Then calculate the length L1 and width H1 of the inner border of the entity object, and further calculate the length L3 of the outer border through the length of the inner border when the inner border is valid, and calculate the scaling ratio M2 of the entity object according to the length of the inner and outer borders. If the zoom ratios are the same, get the corner stamp information. The positive effect of the present invention is: by calculating the zoom ratio of the map frame, and then reading the corner stamp information through the method of coordinate positioning, the method of the present invention can not only ensure the correctness of information acquisition, but also ensure that the map frame can conform to standard specification requirements.

Description

technical field [0001] The invention relates to a method for extracting corner stamp information. Background technique [0002] The key information in the drawing file is stored in the corner stamp, which includes the design unit, project name, file number, major, designer and other information. When the designers and archives personnel submit and file the drawings, they need to manually check whether the design unit, project name, project number, and file number are filled in incorrectly. If no mistakes are made, the personnel in the archives room still need to manually input professional and designer information into the system. The workload is heavy and error-prone. At the same time, whether the size and placement of the text cells conform to the standard position is difficult to use with human eyes. Check it out. [0003] The existing technology mainly uses the keyword set by the template to find the location and area of ​​the cell, and then reads the data in the cell....

AI Technical Summary

Problems solved by technology

[0004] (1) The cell storing the data is unintentionally elongated or widened. Although the data content can be obtained, it is impossible to judge whether the placement of the cell meets the requirements of the relevant standards;

[0005] (2) If the cell has no keywords or repeated keywords, there will be a recognition error, and the data of the specified cell cannot be obtained 100% successfully;

[0006] (3) The operation is complicated and multiple templates need to be made
