Abstract

The invention discloses a method and device for determining document orientation, and relates to the technical field of computer vision. A specific embodiment of the method comprises the steps of obtaining an image of a to-be-tested document comprising a table; inputting the image of the to-be-detected document into a trained key point detection model to obtain key point information, output by thekey point detection model, of a table of the to-be-detected document, the key point information representing positions of at least two preset key points, associated with the document orientation, ofthe table in the to-be-detected document; and determining the orientation of the to-be-tested document based on the key point information of the table of the to-be-tested document. According to the embodiment, the document orientation can be accurately and efficiently detected.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, in particular to the field of computer vision technology, and in particular to a method and device for determining document orientation. Background technique [0002] The main function of image recognition technology is to distinguish the objects in the image according to the observed images, so as to make corresponding meaningful judgments. The known process is simulated. [0003] In document processing technology, it is often necessary to recognize multiple text images from document images through image recognition technology, and use the recognized text images to perform subsequent processing such as document orientation correction and optical character recognition. [0004] When correcting the direction of a document image, it depends on accurate document orientation detection. The current document orientation detection technology is insufficient in accuracy and...
