Abstract
Virtual production enables the coordinated movement between real actors'performances and the virtual scenes displayed on LED screens from the camera's perspective.Virtual-real coordination requires that the virtual camera in the virtual environment has the same pose and lens parameters as the real camera.Currently,the mainstream technology for obtaining the pose of a real camera is the optical tracking method.The optical tracking camera is fixedly connected to the main camera,and calculates the camera's pose by analyzing the status of optical markers within the field of view of the op-tical tracking camera.These optical markers are scattered on the ceiling or floor of the studio.However,this method has drawbacks:it is costly,the optical markers occupy shooting space,and they cause physical or optical interference with the lighting system.This paper proposes a FREE-D protocol data conversion device that can directly obtain the pose of the end camera from the robotic arm,while acquiring lens parameters via mechanical gears.When triggered by the Genlock synchronization clock,the device sends the latest camera pose and lens parameters to the virtual-real composition server.Through the actual deployment and use of the device,it is proven that the system features low cost,simple installation and operation,no occupation of physical or optical space during shooting,and the ability to track any movement of the camera.关键词
