Abstract

A method for calibrating a scanned document, which is applied in the technical field of electronic terminals, the method includes: confirming the number of cameras, opening a designated camera according to the number of cameras, and judging the plane of the document and the electronic device through a distance measurement method corresponding to the number of opened cameras If it is parallel, then judge whether the distance between the document and the electronic device is within the preset range according to the proportion of the interface image of the document in the camera preview screen, and if it is within the preset range, then judge the Whether the direction of the content of the document is aligned with the auxiliary grid line in the preview screen of the electronic device, and if so, it prompts that the electronic device has finished scanning and correcting the document. The embodiment of the invention also discloses an electronic device and a computer-readable storage medium, which can quickly adjust the positional relationship between the document and the electronic device before photographing and identifying the content of the document, and improve the convenience of photographing and identifying the content of the document , accuracy and efficiency.

Description

technical field [0001] The invention belongs to the technical field of electronic devices, and in particular relates to a scanning document correction method, an electronic device and a computer-readable storage medium. Background technique [0002] When rectifying the tilted or distorted image that has been taken to restore the scanned image, there is a lack of processing of the scanning system itself to achieve non-distorted and non-slanted scanning. This scanning correction technology relies on hardware platforms such as computers. When the scanned image is severely distorted, it is difficult or even impossible to correct the image. [0003] With the development and progress of mobile smart terminals, the camera pixels have been able to achieve a photo effect comparable to that of scanners. Scanning with mobile phones has the advantages of fast, convenient, and easy to share, and character recognition can be performed after scanning. The content is extracted. However, th...
