MODE INTRODUCTION
Wide Area Mode
Application
This mode is suitable for teacher or lecturer tracking in normal classroom. The algorithm is
based on face detection.
Regardless of the target close to or away from TR320, the tracking camera will automatically
zoom in/out to maintain the appropriate size and proportion.
If the tracking target is locked, TR320 will not be affected by the other moving objects.
Limitation
This mode is easily affected by the brown objects or the color similar to skin. Things like cartons
and wood furniture.
It should be used in a brightly lit environment. If the light level is not enough, it may not be able
to properly track the object.
It should not be used in an environment with high bright contrast. For example, the environment
with lots of IFP or projectors in the background. When the target enters or leaves the high bright
contrast zone, the TR camera may not be able to track the object properly.
