FYP2008 Vision-based Marker Tracking Using Multiple Cameras

Project Members:

Idea:
Most of Mixed Reality applications are using a single camera for tracking target marker. Single camera has a limited field of view subject to the different lens used. A single camera can be used to cover a working area in which the fiducially marker will be placed for tracking. Working area coverage can be enlarged by placing the camera further away from the working area. However, this reduces the pixel size of the marker in the video captured by the camera. This will also further lead to the instability of the tracking since the available pixels of the marker to be tracked are getting less.

The aim of this project is to use multiple cameras to solve this problem. Each camera will be assigned to cover different working area. Therefore, multiple camera tracking will greatly widen the working area. However, proper calibration needs to be done among all cameras. The challenge of this project is to make the calibration process automatic. After getting the relationship among cameras, tracking transition from one camera to the other should be smooth.
