Embodiment 1

[0055] combined with Figure 1-5 , the present embodiment proposes a method for assisting the operator to make a standard ID card photo. The method first locates six key points of the head in the original image, namely, the nose, the right eye, the left eye, the right ear, the left ear, and the top of the head. , and then calculate the candidate boundary according to the ID card production standard for the operator to choose. After the operator selects the candidate boundary, the original image is automatically scaled to the standard image according to the candidate boundary, so that the zoomed and cropped avatar meets the resolution requirements.

[0056] In this example, combined with the figure 2 , use the camera to take original images that match the background, dress, expression, and demeanor;

[0057] There is clipping space around the head in the original image;

[0058] Raw images are stored in a standards-compliant image format.

[0059] In this example, combined ...

Embodiment 2

[0074] combined with Figure 1-6 , present embodiment proposes a kind of tool that assists operator to make standard ID card photo, and its structure comprises:

[0075] Acquisition module 10 is used to collect the original image taken. The original image meets the background, dress, expression, and expression requirements of the ID card photo. There is a clipping space around the head in the original image. The original image is stored in a standard image format .

[0076] The human face key point positioning model 20 is used to position the positions of the nose, right eye, left eye, right ear, and left ear in the original image in order to obtain the coordinates of the nose, right eye, left eye, right ear, and left ear Location;

[0077] Image binarization processing module 30, is used for converting original image into grayscale image, and further obtains the coordinate position of the top of the crown of the head;

[0078] Calculation module 40, according to the coordi...

Abstract

The invention discloses a method for assisting an operator in making a standard identity card photo, relating to the technical field of image processing. The method comprises the steps of positioning six key points of a nose, a right eye, a left eye, a right ear, a left ear and a head top tracing top end of a head in an original image; according to the identity card making standard, calculating candidate boundaries for an operator to select, after the operator selects the candidate boundaries, automatically zomming an original image into a standard image according to the candidate boundaries, wherein the zoomed and cut head portrait meets the resolution requirement, and achieving rapid making of a standard identity card photo. The invention also discloses a tool for assisting the operator in making the standard identity card photo, and the tool can be applied to the field of intelligent image processing by being combined with the method.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and a tool for assisting operators in making standard ID card photos. Background technique [0002] my country's "Technical Requirements for Digital Photos for Resident ID Card Production" provides detailed standards for the style and specifications of digital photos. The photo has a width of 358 pixels and a height of 441 pixels, with a white background and no borders. The "Technical Requirements for Digital Photos for Resident ID Card Production" also restricts the size and position of the head portrait, requiring the portrait to be horizontally centered, the width of the face to be 207±14 pixels, the distance between the eyes and the bottom edge of the image should not be less than 207 pixels, and hair on the top of the head. The distance from the upper edge of the image is 7 to 21 pixels. When the eyes and the hairline on the top of the head cannot meet the...
