スタジオ番組用移動ロボットカメラの開発

摘要

We have developed a mobile robot camera that can move in any lateral direction, as well as up and down, as a tool for efficient program production. The system adopts methods that utilize a gyrosensor and the number of wheel revolutions to determine the camera's position, and that enable a high degree of positioning accuracy. It also uses a unique filming algorithm that simulates the operation methods used by human camera operators. Therefore, the robot camera can shoot scenes with natural camerawork. Moreover, we have developed a highly accurate image composition system using this mobile robot camera as a tool for the efficient production of HD virtual studio programs. The system is currently being operated on a continuous basis as a practical camera in live broadcasts as well.%ロボットカメラの番組利用は，当初，屋外や高所での撮rn影や定点での連続撮影など，人では困難で手間を要する用rn途に限られていた．その後，ロボット技術の発展により，rn高速な雲台や高精度なセンサが比較的容易に入手できるよrnうになり，高機能なロボットカメラが生まれている．
