Problems solved by technology

[0005] The disadvantage of method 1 is that it requires a specific background color palette and draws a pattern with specific identification features. The site preparation process is more complicated. At the same time, the accuracy of the camera's image recognition is very high. When the camera captures a blurred picture, the tracking accuracy will change. Poor, and this method can only be used in a virtual studio with a specific background color palette, and cannot be used in an augmented reality studio for live action shooting
The disadvantage of method 2 is that corresponding sensors must be installed on each moving part of the camera, which is expensive, and the accuracy is limited by the precision of machining and sensors, and the tracking error is difficult to control. Consistent, and there must be someone operating the camera's movement

Embodiment 1

[0054] Embodiment 1, a method for simulating camera motion tracking in a virtual studio, such as figure 1 shown, including:

[0055] Step 1: Obtain the real-time high-resolution video images taken, and obtain the motion parameters of pan, pitch and lens zoom;

[0056] Such as figure 2 As shown in the figure, ultra-high-definition cameras are arranged in the virtual studio to shoot real-time video images of 3840x2160 pixels. The ultra-high-definition video signal captured by the camera is input to the video processing module in the system. It is worth mentioning that the frame size captured by the present invention is not limited to 3840x2160 pixels, and can also be applied to situations with higher or lower pixels.

[0057] The motion parameter acquisition methods of Pan, Tilt and Zoom can be preset by the program or input by the operator in real time.

[0058] Step 2: Generate a dynamic video result screen that simulates camera motion according to the motion parameters o...

Embodiment 2

[0083] Embodiment two, a kind of method for the simulation camera motion tracking of augmented reality studio, such as Figure 7 shown, including:

[0084] Step 1. Obtain the real shot high-resolution video image, and obtain the motion parameters of pan, pitch and lens zoom;

[0085] Such as Figure 8 As shown, ultra-high-definition cameras are arranged in the studio to shoot 3840x2160 pixel images. The ultra-high-definition video signal input processing system for real shooting by the camera. It is worth mentioning that the frame size captured by the present invention is not limited to 3840x2160 pixels.

[0086] The motion parameter acquisition methods of Pan, Tilt and Zoom can be preset by the program or input by the operator in real time.

[0087] Step 2, according to the motion parameters of pan, pitch and lens zoom, simulate the motion of the camera to generate a dynamic video result screen with specified resolution;

[0088] Such as Figure 9 As shown, the dynamic vi...

Abstract

The invention discloses a video processing method and device for analog camera motion tracking in a studio, and relates to the technical field of video signal processing. The technical points of the method include obtaining the real-shot high-resolution video picture, obtaining the motion parameters of pan, pitch and lens zoom; The dynamic video result picture of simulating camera movement; on the virtual scene model, according to the motion parameters of pan, pitch and lens zoom, generate the virtual scene result picture of simulating camera movement; or on the enhanced object model according to pan, pitch and lens zoom motion parameters to generate an augmented reality object result picture that simulates camera movement; the dynamic video result picture and the virtual scene result picture or the augmented reality object result picture are synthesized in the key mixer and the final synthesized result picture is output. The present invention has the advantages of low implementation cost And the advantages of simple implementation.

Description

technical field [0001] The invention relates to the technical field of video signal processing, more specifically, it relates to a video processing method and device for analog camera motion tracking in a studio. Background technique [0002] The chroma key keying technology is used in the virtual studio, by placing the foreground (usually the host) in front of a background board of a specific color, and then cutting out the background part of the specific color captured in the picture, and replacing it with the rendered virtual background A background of a specific color is used to compose the output composite image. Augmented reality studios use key-mixing technology to superimpose augmented objects onto captured footage. This all requires that in the practical application of virtual studio and augmented reality studio, when the camera pans, tilts and zooms, the rendered virtual background or enhanced objects must be kept in absolute synchronization with the shooting pict...
