Scene matching apparatus and method for virtual studio

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-dime
