Abstract
The present invention relates to an opto-mechanical camera position tracking device which gathers real-time positional data of camera in three dimensional (3D) space and zoom value of the camera lens without using any line of sight or markers and has zero drift. The said camera tracking device attaches to an existing camera crane, detects the necessary positional and optical data, processes it, and sends it to a rendering engine for seamless, real-time visualization.
Claims7
An opto-mechanical camera position tracking device, the said device comprising:
- a dolly wheel encoder unit;
- a lens encoder unit;
- a pedestal pan encoder unit;
- a head pan and tilt encoder unit;
- a pedestal tilt encoder unit;
- a printed circuit board
- characterized by mounted sensors and encoders on jib and camera and gathering of real-time positional data of camera in three-dimensional (3D) space and zoom value of the camera lens without using any line of sight or markers and has zero drift and wherein the dolly wheel encoder unit comprises an encoder, an encoder shaft screw, an encoder wheel, a grub screw, a spring, a trolley wheel extension rod, and a wheel encoder mounting plate and is fixed to the base of the jib pedestal to collect the rotational data of the wheels.
