Hello,
This may seem like an odd project, but I don't really know where to start, so I thought I would find and ask some experts lol. Thanks in advance for your help. Here is the story:
I am a Computer Science guy who dabbles in making short films and visual effects. I just took an intro to electronics engineering course and had an idea.
First, some background information: In visual effects it is very important to be able to match the movement of the live action camera with the computer so that the digitally generated effects will blend in properly. There is a whole area of visual effects dedicated to 3D tracking.
My idea is this. They make electronic accelerometers, as well as electronic gyroscopes fairly cheap. Wouldn't it be possible to mount a device that has an accelerometer and a gyroscope for each axis onto a camera, and then record the acceleration and orientation data?
That data could then be used to derive the position and orientation of the camera at any point in time within the accuracy range of the device? You would know the camera's starting position, velocity, acceleration, and orientation. What ever point it starts at would be considered the 0 position. Couldn't you then use the acceleration data with the Newtonian position equation (X =
