Embodiment Construction

[0018] Please see figure 1 As shown, the present invention provides a kind of real-time matting and video acquisition method, which comprises:

[0019] Step 101, acquire an image of a shooting device.

[0020] The shooting device may be a camera or a camera. In a specific embodiment, in order to achieve the best video effect, a high-definition camera is used to shoot pictures to improve user experience.

[0021] Step 102, using a keyer to acquire a foreground image of the image acquired by the photographing device.

[0022] Step 103, using Directshow SmartTee technology to collect and monitor high-resolution video at a synchronous frequency. SmartTee technology supports decomposing one stream into two streams for different processing. When connecting SmartTee with other filters, SmartTee cannot be used as the pSource parameter of ICaptureGraphBuilder2::RenderStream(), because the output Pin of SmartTee does not use PinCategory.Capture or PinCategory.Preview mode, so it can ...

Abstract

The invention discloses a real-time matting and video monitoring and collecting method which includes the following steps: acquiring the image of the shooting equipment; using a matting machine to acquire the foreground image of the image acquired by the shooting equipment; collecting and monitoring the high-resolution video at synchronous frequency through Directshow Smart Tee technology; and combining the foreground image acquired by the matting machine with the selected background image to produce a composite image. When a satisfactory composite image is acquired, a picture can be produced by print-screening the composite image acquired in the screen through screen capture technology.

Description

technical field [0001] The invention relates to a video acquisition and processing method, in particular to a video matting acquisition and processing method. technical background [0002] Existing image keyers have been used in film and television creation, but there is still a gap in exhibition display and user entertainment interaction. Existing keyer users cannot achieve real-time synthesis with the local pre-stored background at the operation end, and they cannot combine it with a video to obtain the effect of shooting a movie by themselves. [0003] While obtaining video images in real time, the prior art cannot capture screenshots and take pictures. In the prior art, it is also impossible for the client to control the opening and output of the image keyer. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a real-time image keying and video collection method, which can enable customers to integrate their own imag...
