Abstract

The present disclosure relates to an image correction method and device, wherein the method includes: acquiring an image of a target area; The area image is divided into a first sub-area image and a second sub-area image; the first sub-area image is projected to the Y axis to obtain a first projection map, and the second sub-area image is projected to the Y axis to obtain a second projection map; according to The first projection diagram and the second projection diagram calculate the angle between the direction of the characters in the target area image and the X axis; rotate the target area image according to the angle so that the direction of the characters in the target area image is parallel to the X axis. Through this technical solution, the direction of the characters in the image of the target area is corrected, which facilitates the character segmentation and subsequent recognition operations.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to an image correction method and device. Background technique [0002] When automatically recognizing a rectangular object image or dealing with other problems, it is often encountered that the ROI (Region Of Interest) of the target text is not horizontal, which will cause great damage to the character segmentation and subsequent recognition. influences. Contents of the invention [0003] Embodiments of the present disclosure provide an image correction method and device, including the following technical solutions: [0004] According to a first aspect of an embodiment of the present disclosure, an image correction method is provided, including: [0005] Obtain an image of the target area; [0006] When the direction of the characters in the target area image is not parallel to the X axis, divide the target area image into a first sub-area image and a sec...
