Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0015] like figure 1 As shown, a game engine image matting dynamic space cutting method, the implementation process includes: firstly receive the video acquisition data and track the actual camera motion data to obtain the current camera positioning information; by establishing a virtual camera, pick up the real camera motion trajectory, and Cloth range Build the same proportion of green (blue) cloth in the virtual environment, and calculate the actual green (blue) cloth range in the virtual environment; based on this, the dynamic green (blue) cloth range mask in the virtual environment is rendered...

Abstract

The invention provides a game engine image-matting dynamic space cutting method. The engine image-matting dynamic space cutting method comprises the following steps: receiving video capture data, tracking the practical camera movement data, and acquiring the current camera locating information; establishing a virtual vidicon, picking up the practical camera movement locus, constructing the green (blue) cloth with the same ratio in a virtual environment according to the practical range of green cloth, and calculating the practical range of the green (blue) cloth in the virtual environment; rendering the dynamic green (blue) cloth range shading in the virtual environment in real time according to the practical range of the green (blue) cloth in the virtual environment, taking the dynamic green (blue) cloth range shading as the passage, and saving the passage in a memory; acquiring a picture after shooting and image matting, and subtracting the range of the green (blue) cloth calculated in real time in the memory aiming at the material after the practical image matting, thus obtaining the image data with the range of the green (blue) cloth removed; and finally, outputting the image with the range of the green (blue) cloth removed. With the adoption of the method, the problem that the shot image is out of the range is solved, and the unrelated objects outside the range of the green (blue) cloth are automatically removed; since the limitation of the green cloth is eliminated, a photographer can shoot at 360 degrees without dead angles.

Description

[0001] Technical field: [0002] The invention relates to a dynamic space cutting method for game engine keying. [0003] Background technique: [0004] The invention discloses a dynamic space cutting method for game engine image matting. The implementation process of the existing technology includes: building a green (blue) cloth environment before shooting, connecting the camera to the computer, inputting data to the game engine, performing keying adjustments to remove the green (blue) cloth, manually adjusting the virtual 3D space to match the current lens, Added tracking module to track actual camera data back to the game engine. If the camera position is moved, when the camera position moves beyond the range of the green cloth, you will see objects outside the screen, such as photographers, lighting equipment, etc., but the current keying method in the game engine will have green (blue) Off-screen objects outside the cloth range cannot be automatically deleted, resulting...
