Drawing scanning device based on OCR recognition

Abstract

The invention belongs to the technical field of drawing scanning equipment, and particularly relates to an OCR identification-based drawing scanning device, which comprises a shell, a control panel and a multi-view scanning mechanism, and is characterized in that the shell is provided with a rectangular through groove penetrating front and back, the lower side and the left side of the shell are respectively provided with a first mounting cavity and a second mounting cavity, and the bottom wall of the first mounting cavity is provided with a mounting block; an adjusting screw rod is rotationally assembled on the mounting block and is in threaded connection with a hollow box, transmission mechanisms are arranged in the second mounting cavity and the hollow box, conveying mechanisms are arranged on the left wall surface of the rectangular through groove and at the end, close to the second mounting cavity, of the hollow box, each conveying mechanism comprises four main shafts, and the fourmain shafts are fixedly connected with conveying wheels; according to the drawing conveying device, flexible adjustment can be conducted according to the size of a drawing, then the drawing can be scanned conveniently, the drawing can be effectively fixed and clamped in the drawing conveying process, and the situation that the scanning recognition effect of an image is affected by curling is avoided.

Description

technical field [0001] The invention belongs to the technical field of drawing scanning equipment, and in particular relates to a drawing scanning device based on OCR recognition. Background technique [0002] Engineering drawings generally refer to two-dimensional drawings that record buildings, lines, equipment, structures, or textual content. Generally, three-view methods are used to record, that is, front view, side view, and top view. Content. [0003] In order to more effectively save or record and edit the contents of engineering drawings, the contents on engineering drawings are generally identified and scanned, and converted into electronic data for preservation, which can not only reduce the trouble of carrying drawings at any time, but also enable the preservation of data For a longer period of time, ordinary scanners are generally used to scan engineering drawings.

Problems solved by technology

[0003] In order to more effectively save or record and edit the contents of engineering drawings, the contents on engineering drawings are generally identified and scanned, and converted into electronic data for preservation, which can not only reduce the trouble of carrying drawings at any time, but also enable the preservation of data For a longer period of time, ordinary scanners are generally used to scan engineering drawings. However, due to the different sizes of engineering drawings with different contents, the general scanner has a small scanning range and can only be used for drawings with smaller paper. The drawings can only use scanners with a larger scanning range, but such scanners are larger in size and more expensive, so this causes inconvenience in scanning engineering drawings. Therefore, when the scanning is unfolded, the drawing will be warped, which will cause the scanned image to be inaccurate, which is not conducive to data collection
