Embodiment Construction

[0022] Such as figure 1 As shown, the scene matching device for a virtual studio of the present invention includes a camera 1 placed at any position in the virtual studio and capturing the foreground, a pitch sensor 2 and a pan sensor 3 installed on the camera 1, and a signal input unit 4. A signal processing unit 5 that performs real-time analysis and processing on the signal input by the signal input unit 4 and converts the foreground position captured by the camera 1 and the coordinate parameters of the current position of the camera 1, and the three-dimensional rendering device connected to the virtual studio The data output unit 7, its three-dimensional rendering device is the virtual studio rendering graphics workstation 9. Wherein, the camera 1 , pitch sensor 2 and pan sensor 3 are all connected to the signal input unit 4 , the signal input unit 4 is connected to the signal processing unit 5 , and the signal processing unit 5 is connected to the data output unit 7 . Th...

Abstract

The invention discloses a picture-setting matching device for a virtual studio and a matching method thereof, the matching device comprises a camera, a pitch sensor and a horizontally-shaking sensor mounted on the camera, a signal input unit, a signal processing unit which analyzes the signal processed by the signal input unit in real time and obtains coordinates parameters of a foreground location and a camera current location via conversion, and a data output unit connected with a three-dimensional rendering apparatus; the matching method comprises the steps of: taking any site in a blue box as an origin of coordinates and establishing a spatial three-dimensional system of coordinates, aligning the lens of the camera to the origin of coordinates, enabling the lens to inerrably face XZ plane or YZ plane via pitch and horizontally-shaking movements; acquiring and transmitting, by the signal processing unit, the coordinates parameters of the foreground location and the camera current location to the three-dimensional rendering apparatus. The inventive device has simple structure and operation, which can effectually solve the issues about perspective relation matching between foreground and three-dimensional virtual scenes and about location relation matching between the camera and the three-dimensional virtual scenes.

Description

technical field [0001] The invention relates to the technical field of perspective relationship matching between collected real scenes and three-dimensional virtual scenes, in particular to a scene matching device and matching method for a virtual studio. Background technique [0002] After more than ten years of development, virtual studio technology has made great progress and has entered the stage of popularization and application. However, as one of the key technologies in the virtual studio system, the perspective matching technology of the real foreground captured by the camera (the host or object in the blue box) and the three-dimensional virtual scene, as well as the matching technology between the three-dimensional virtual scene and the position of the camera, are now All still lack effective matching method and device thereof now. In practice, there are differences in the visual perspective effect of observing the same object from different positions and different...
