Considering
a sensor system for robot vision, which is applicable for all-purpose use
just by a single sensor, fovea vision, observed in the human vision system,
is quite interesting. One of the most
remarkable advantages of this unique vision system is to reduce the number of
data drastically in the entire field of view (FOV). Moreover, fovea vision can realize both wide-angle field of
view (FOV) and high resolution in the central FOV, simultaneously. Although a couple of methods have been
proposed to acquire such a foveated image, an optical approach is the best
for the highest resolution in the central FOV. We often represent this space-invariant image by Log-polar
mapping (LPM), which is one of the most beautiful and rational ways to
acquire such an image, on earth.
Fig.1 shows a wide-angle foveated (WAF) image from a special WAF lens. Fig.2 shows the LPM image from the WAF lens. Fig.3 shows a stereo camera’s view
direction control (VDC) device.
