NHK to enhance instant replays with motion tracking bullet time camera system

first_imgBullet time has become a common site in movies ever since The Matrix used it to such good effect. But bullet time camera capture systems are typically quite limited based on the need for multiple cameras setup to look at a specific area in order to capture the action from every angle. Japanese broadcasting company NHK aims to change that, though, by adding motion tracking into the mix.What NHK has done is to link all of the bullet time cameras to a single, moving camera controlled by a cameraman. As he moves his camera, all the other cameras in the system also move. By doing this, the system can track the action over a much larger area than was previously possible.For now, the NHK system can have 8 motion tracking cameras hooked up to a controlled camera, but there’s nothing to stop you having multiples of these to surround the action on say, a sports field. Software is also used to automatically adjust the camera rotation and to perform image processing therefore allowing a smooth transition between camera views.So what does this mean in real terms? Well, sporting events are going to be the focus of such a system. You can still have the main cameras tracking the action, but they can now be linked up to an array of unmanned cameras that automatically track and record the action from every angle. Broadcasters then get access to a 360-degree view of key events 60 seconds after they happened, and therefore so do viewers.Such a system is going to need a serious amount of data storage and processing power to back it up, especially now that we demand all our sports and entertainment in HD. But I think it’s worth it, and Hollywood is also sure to show an interest for use of such a system with the larger action scenes in movie productions.last_img
