Embodiment approach

[0059] A feasible implementation scheme for judging whether the resolution of the face area meets the requirements is as follows:

[0060] Set the minimum horizontal resolution of the face area to T fwidth , with a minimum vertical resolution of T fheight , then if fwidthfwidth or fheightfheight , it is considered that the resolution of the face area does not meet the requirements, and prompts to reduce the distance between the subject and the image acquisition device (for example, ask the subject to be closer to the image acquisition device to shoot);

[0061] Step 230, judge whether the distance between the face and the edge of the image is appropriate according to the position and size of the face, if not appropriate, prompt and go to step 110, otherwise, perform the next step;

[0062] A feasible implementation scheme for determining whether the distance from the face to the edge of the image meets the requirements is as follows:

[0063] Define the ratio of the distance...

Abstract

The invention provides an image automatic acquisition method, which comprises the following steps: (a) collecting an image; (b) analyzing the image to obtain image parameters; (c) judging whether the image meets pre-specified requirements on the image according to the image parameters, if yes, extracting the collected image according to scheduled rules, otherwise, prompting an adjustment and returning to step (a). The invention also provides an image automatic acquisition device, which comprises a main control unit for controlling and managing other units, an image collection unit for collecting the image, an image parameter extraction and judgement unit for analyzing the image to obtain the image parameters and judging whether the image meets the requirements, if no, a prompt is given, and the main control unit controls the image collection unit to collect the image again, if yes, the main control unit gives the prompt to an image generation unit to extract the image according to the scheduled rules.

Description

technical field [0001] The invention relates to an image automatic acquisition method and device. Background technique [0002] In daily life, it is often necessary to take ID photos, such as ID cards, passports, driver's license photos, etc. ID photos generally require a fixed size, the subject’s head is at a fixed position in the photo, and the size is within a certain range, and there are also certain requirements for the posture and lighting conditions of the head. [0003] The existing methods are all taken manually in a photo studio, and then the range of the photo is manually determined, and then cut and zoomed to a fixed size. The size and range of the portrait area in the photo are determined entirely by naked eyes, and the posture of the person being photographed is adjusted during the shooting process. , It is completely determined by people, and it is very inconvenient and inaccurate to shoot. Contents of the invention [0004] The technical problem to be sol...
