Mirror design
- 1. The mirror occupies only a small part of the image
- not bigger than the fovea!
- 2. Constant angular resolution!
- 3. ???????? radial resolution!
- 4. Experiment with the SVAVISCA camera and the existing mirrors must
be done before doing the design!
Applications
- 1. Low resolution virtual tele-presence cameras possible!
- 2. Image based orientation of mobile robots possible!
- 3. Motion detection for surveillance possible!
