Embodiment Construction

[0067] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0068] Such as figure 1 As shown, in one embodiment, a method for correcting a distorted human face image is provided, the method comprising:

[0069] Step 102, acquiring an image to be processed.

[0070] In this embodiment, the image to be processed may be an image collected by a device such as a smart camera using a wide-angle lens, the image includes a human face, and the image as a whole has image distortion.

[0071] Step 104, using a face detection method to detect and extract a face area in the image to be processed.

[0072] In this embodiment, the face detection method based on the con...

Abstract

The invention relates to a distorted human face image correction method, device, computer equipment and storage medium. The method includes: acquiring an image to be processed; detecting and extracting a face area in the image to be processed by a face detection method; Point coordinates: using a pre-trained image correction model to perform image correction according to the key point coordinates, wherein the image correction model is obtained by training multiple pairs of normal images and distorted images. Image correction is performed on the face in the image to be processed according to the face feature information and the image correction model, thereby reducing the amount of computation and enhancing the correction effect of the face image.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a distorted face image correction method, device, computer equipment and storage medium. Background technique [0002] With the rapid development of modern technology, smart cameras have been widely used in the security field. In order to obtain a larger monitoring field of view, smart cameras often use wide-angle lenses, which leads to radial distortion of faces in images captured by smart cameras, which adversely affects subsequent processing such as face detection and recognition. [0003] At present, there is no correction algorithm for the radial distortion of the face image. In traditional technology, the image captured by the smart camera is often used for full image correction, and then the face in the image is corrected. This method has There may be human error, which affects the correction result. Compared with only correcting the face, it is necessary to revers...
