A new generation of inexpensive robotic pan-tilt cameras can maintain high-resolution panoramic displays of natural environments. However, the pan-tilt mechanisms are imprecise: small errors can produce large errors in the panoramic display. It is thus important to accurately estimate pan-tilt values. We present a new calibration algorithm that does not… CONTINUE READING
