Automatic keying camera based on human pose

Abstract

The invention relates to an automatic image-matching camera based on human body posture, comprising: a power detection device, which is used to detect the current remaining power of the camera, and sends a first alarm signal when the current remaining power is less than or equal to a first preset percentage threshold, When the current remaining power is less than or equal to the second preset percentage threshold, a second alarm signal is sent; the indicator light is used to display with different flashing frequencies when the first alarm signal or the second alarm signal is received; The CCD sensor device is used to shoot the current scene to obtain and output the current scene image; the real-time matting device is used to use the sharpened image of each human target in each posture and non-photographing posture as the actual output image. Through the present invention, it is possible to meet the user's requirement for extracting the background portrait in the image.

Description

technical field [0001] The invention relates to the field of cameras, in particular to an automatic image-matching camera based on human body posture. Background technique [0002] From the perspective of completing the function of photography, the camera generally has three major structural systems: imaging, exposure and auxiliary. Imaging system includes imaging lens, ranging and focusing, viewfinder system, additional lens, filter mirror, effect mirror, etc.; exposure system includes shutter mechanism, aperture mechanism, metering system, flash system, Selfie mechanism, etc.; auxiliary system includes film winding mechanism, counting mechanism, rewinding mechanism, etc. [0003] The lens is an optical system for imaging, which is composed of a series of optical lenses and lens barrels. Each lens has two characteristic data of focal length and relative aperture; the viewfinder is a device used to select the scene and compose the picture. Any part of the scene that can fal...

Problems solved by technology

[0008] In the prior art, the following problems often occur in camera shooting: irrelevant human bodies often appear in photographed and imaged pictures, and in order to maintain a clean background and ensure the effect of taking pictures, these human bodies need to be extracted, and the current real-time shooting cannot To solve this problem, the keying operation can only be performed through various PS operations in the later stage, which will inevitably affect the quality of the image
