Picture correction method and device based on facial feature point detection, and computer equipment

Abstract

The invention discloses a picture correction method and a device based on facial feature point detection, computer equipment and a storage medium. The method comprises the steps of acquiring a specified certificate picture including a human face; placing the specified certificate picture according to a first posture so as to obtain an intermediate certificate picture; inputting the intermediate certificate picture into a preset facial feature point detection model for processing to obtain a first feature point number; if the number of the first feature points is not greater than a preset number threshold, clockwise rotating the intermediate certificate picture by a specified angle to obtain a rotated certificate picture; inputting the rotating certificate picture into a facial feature point detection model for processing to obtain the number of second feature points, and judging whether the number of the second feature points is greater than the number threshold value; and if the number of the second feature points is greater than the number threshold, marking the rotary certificate picture as a corrected picture. Therefore, accurate correction of the certificate picture is realized.

Description

technical field [0001] The present application relates to the field of computers, in particular to a method, device, computer equipment and storage medium for image correction based on facial feature point detection. Background technique [0002] With the development of artificial intelligence, there are more and more scenarios for the analysis of documents by artificial intelligence. The angle correction of the document is a very important function, which has a great impact on the accuracy of the text recognition of the document, and also affects the accurate analysis of other aspects of the document. If the ID card can be corrected to the standard angle for any angle, then the text or image will be very close to the human visual experience, and it will be beneficial to the subsequent image processing technology such as text extraction. The traditional angle correction of the document needs to find the coordinates of the four vertices of the document. In the end, the docum...

Problems solved by technology

The traditional angle correction of the document needs to find the coordinates of the four vertices of the document. In the end, the document can only be corrected to 0 degrees (that is, the standard posture, which is the most suitable posture for viewing or processing), 90 degrees, 180 degrees, and 270 degrees. One of the four, but it is impossible to determine which of the four the corrected angle is, so it is not conducive to subsequent image processing

Therefore, the prior art lacks a technical solution for accurately correcting the document picture
