Positioning method of camera in virtual reality shooting scene and camera bearing equipment

Abstract

The invention relates to a method for positioning a camera in a virtual reality shooting scene and camera bearing equipment, the camera is arranged on the camera bearing equipment, the camera bearing equipment has a fixed equipment zero point, and the virtual reality shooting scene has a shooting coordinate origin. The positioning method comprises the following steps: in a coordinate system taking an equipment zero point as a coordinate origin, acquiring a first position coordinate of a camera at a first position relative to the equipment zero point and a first inclination angle relative to a shooting coordinate origin, acquiring a second position coordinate of the camera at the second position relative to the zero point of the equipment and a second inclination angle relative to the origin of the shooting coordinate; and according to the first position coordinate, the second position coordinate, the first inclination angle and the second inclination angle, calculating the position coordinate of the shooting coordinate origin in the coordinate system taking the equipment zero point as the coordinate origin, and through coordinate conversion, obtaining the position coordinate of the equipment zero point in the coordinate system taking the shooting coordinate origin as the coordinate origin.

Description

technical field [0001] The invention relates to the technical field of video equipment, in particular to a method for positioning a camera in a virtual reality shooting scene and a supporting device for the camera. Background technique [0002] To realize virtual reality shooting in a broadcast studio, it is necessary to calculate the position and angle relationship of the camera relative to the studio coordinate origin in real time. Virtual equipment such as virtual rocker arm and orbital robot use photoelectric and magnetoelectric encoders to calculate the position and angle relationship of the camera relative to the zero point of virtual equipment such as virtual rocker arm and orbital robot in real time. Then how to obtain the positional relationship between the camera and the coordinate origin of the studio is the problem to be solved by the present invention. [0003] The most direct and accurate way is through manual measurement. Usually, there will be a mark of the...

Problems solved by technology

[0011] 1. Some virtual studio blue boxes are made of expensive materials. Sticking identifiable mark points on the studio wall will affect the look and feel and quality of the entire studio, and colored marks will also impose requirements on virtual studio cutouts

[0012] 2. Artificially cross the zero point A in the studio, draw a line segment parallel to the ground, and the end point of the line segment is B, and make a mark. Sometimes this process is not smooth, for example, the zero point A of the studio is not on the background wall of the blue box , then the line segment drawn parallel to the ground at the zero-crossing point A will be suspended, and it is impossible to mark B in the air

[0013] The above problems show that this "two-point positioning" method still has limitations
