Abstract

The invention relates to an image acquisition and correction method. The method comprises the following steps: providing an image acquisition device; moving the image acquisition device in a designated direction to obtain an acquired image and location information; carrying out correction actions on the acquired image; obtaining a skew angle of the acquired image; setting coordinate values of theacquired image as target values; carrying out calculation according to the target values and the skew angle to obtain correction values; replacing the target values with the correction values; judgingwhether to continue the correction actions or not; and completing the correction actions and storing the corrected acquired image. Therefore, the skew of the acquired image can be corrected, and themore accurate correction values can be obtained, so that the acquired image can be more precisely corrected.

Description

technical field [0001] This case relates to an image capture and correction method, in particular to an image capture and correction method for correcting captured images based on location information. Background technique [0002] With the advancement of technology and the popularization of electronic products, the demand for digitizing paper documents has also increased. Generally speaking, paper documents can be converted into digital documents by means of image capture such as scanning or photography. Among them, image capture by scanning can obtain better image quality, and it is also easier to perform character recognition and other operations. [0003] Currently, there are many scanner products on the market, such as flatbed scanners or hand-held scanners. Compared with flatbed scanners, handheld scanners are lighter and more portable, and can instantly and quickly capture images from paper documents to obtain digital image files. [0004] However, when using a han...
