Problems solved by technology

However, setting the gyroscope in the camera will increase the cost of the equipment, and the shooting angles obtained by the gyroscope are usually only 4 fixed angles, and it is impossible to describe the angles other than these 4 angles in detail

Abstract

A method and apparatus for correcting an image is disclosed in embodiment of that present application. One embodiment of the method includes determining at least one sampling angle within a preset angle range; For each of the at least one sampling angle, rotating the target image by the sampling angle to obtain a rotated image corresponding to the sampling angle; Inputting the rotated image into apre-trained non-rotated image detection model for each of the obtained at least one rotated image to obtain a non-rotated image score corresponding to the rotated image, wherein the non-rotated imagedetection model is used to characterize a correspondence relationship between the image score and the non-rotated image score; The rotated image having the highest non-rotated image score among the at least one rotated image is determined as a corrected image corresponding to the target image. This embodiment eliminates the need for a camera to set a gyroscope for capturing images and allows therotation angle of the images to be determined at a finer granularity.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technologies, and in particular to methods and devices for correcting images. Background technique [0002] At present, there are a large number of occasions where it is necessary to correct the rotation angle of the image, so that the people and objects in the corrected image are at normal, forward, and upright angles. For example, in the process of image recognition, training sample images are usually used to establish image recognition models in advance, and the people and objects in the training sample images are usually taken at normal, forward, and upright angles. The normal posture of is not rotated. In the process of image recognition, there are often images to be recognized during the shooting process. Because the camera has a rotation angle during shooting, the people and objects in the image to be recognized also have rotation angles, which will reduce the accuracy o...
