Problems solved by technology

Traditional image methods are sensitive to noise and are prone to misdetection, while deep learning requires high hardware equipment for high-resolution image detection of pixel-level changes; engineering drawing content changes in various forms, including text content changes, partial changes in graphics, local displacements in graphics, and graphics. The overall displacement, etc., including the overlapping and accumulation of these changes, the existing methods have poor detection effect
[0005] The content of engineering drawings is diverse and detailed, and its feature changes are often unpredictable and unpredictable. However, as a standard drawing file, it has certain fixed characteristics: engineering drawings normally have frame lines and title bars

Abstract

The invention discloses an engineering drawing comparison device and method based on computer vision. The device comprises a user interaction assembly, a data relation management assembly, a data processing assembly, a drawing page matching assembly and a drawing difference detection assembly. Based on the engineering drawing file with the front and back version relation, the relation comparison searching is carried out under the condition that the content pages are misplaced, and after the comparison relation is determined, the image comparison method based on computer vision is used for detecting the difference content in the image, the comparison result is displayed to a user and engineering drawing file proofreading is efficiently carried out; therefore, the time and labor cost are saved, and the accuracy of the comparison result is improved at the same time.

Description

technical field [0001] The invention relates to the technical field of intelligent identification and the field of computer vision, in particular to a device and method for comparing engineering drawings based on computer vision. Background technique [0002] During the review process of engineering drawings, drawing reviewers often need to manually review the current version and the previous version of the same project engineering drawing file to check whether the content of the current version of the drawing follows the corresponding design specifications, or whether there are any violations in the file Modify the content. [0003] The comparison of existing engineering drawing files is generally completed by professional drawing reviewers, or using general-purpose image-text difference recognition software to assist detection, but such software often cannot achieve good results in engineering drawing detection. [0004] Due to the large content of engineering drawing fil...
