360 degree shooting/projecting |
|
|
Hi,
I am looking to shoot from a stationary point, and span 360 degrees at
a specific rate. Once complete, I'd like to then project that footage
from the camera location, rotating the projector at the same rate. Any
ideas for technical implementation would be much appreciated!!

You need to build a platform that sits on a motorised turntable. This
turntable needs to be able to have a camera bolted to it. You will need to
build a motor control system with regulatable velocity, so you can dial in a
motor speed and lock it.
Shoot your footage with that.
Mount your projector on the same rig. If you need continuous rotation,
you'll need a wireless video transmitter. Power will need to be fed through
a brush-post system, as well, which is not easy to construct.
Good luck! |

What's your budget? Motorised camera mountings are an off-the-shelf
item. Or you could build something.
One rotation, or many? If many, the cables will become a problem.
Tell us more about the precise requirements for the projection stage. |

Hi, thanks for your reply.
My project has been slightly modified. Two stages now exist: the first
is for shooting the video. The second is the actual display of the
video in a 360 degree envrionment.
For shooting, I was thinking of creating a long stage that matched the
diameter of the environment. I will shoot on a straight track set at a
constant rate.
One complete, I want to map the linear shot onto the cylindrical walls
of the environment, and project the video 360 degrees around at the
same rate that the video was shot with.
I will need three rotations, possibly four depending on user input.
The rotations will be slow and not continuous. I realize that the
cables will be an issue here.
I was also considering rear-projecting the footage for a cleaner look
and no possibility of blocking the line of projection, but it seems
that that may be technically more difficult. I think I'd need the
projector on some sort of motorized track surroundung the 30 ft
diameter structure.
My budget should allow for off-the-shelf purchases, and I am interested
in anything that may already exist rather than having to rebuild an
existing product.
Thanks so much! |
