Abstract

The disclosure provides an automatic photographing method and device. Wherein method comprises: acquisition step, obtains preview image in real time, and preview image comprises to-be-detected frame image; Detection step, detects all human faces in the to-be-detected frame image, and extracts the key point of human face; Judgment step, based on key point, judges Whether all the preset photographing conditions are met, if not all the preset photographing conditions are met, the next frame image of the frame image to be detected is obtained as the updated frame image to be detected, and the detection step is returned; if all the preset photographing conditions are satisfied The condition is to execute the saving step; the preset photographing conditions include: all faces conform to the preset standard of the face, and the opening and closing degree of the eyes is greater than the opening and closing degree threshold; the saving step is to save the frame image to be detected. By automatically identifying the status of the person who needs to be photographed in the image during the preview, it is possible to efficiently capture an image in which everyone is in good condition.

Description

technical field [0001] The present disclosure generally relates to the field of image recognition, and specifically relates to an automatic photographing method. Background technique [0002] When people are taking a group photo, it is difficult to take a good group photo because there are many people in the picture. Usually after taking a photo, you will find this situation: someone among the people being photographed is looking around; or someone’s expression is not natural; or someone’s eyes are closed due to blinking and other reasons; or someone The eyes happen to be looking elsewhere, the line of sight is not directly facing the camera, etc. All of the above situations will make it difficult to take a good group photo. [0003] At present, taking a group photo only relies on the photographer to observe the situation of all the people being photographed, and manual operation is required to take the photo. Because the photographer cannot observe everyone at the same t...
