Thanks to the dynamic range provided by both logarithmic sensors, it is possible to set the exposure time and the
frame rate at fixed values without risk of saturation. This means that gain and exposure time control becomes very
simple for stereo vision systems. The wide dynamic range provided within a single frame for the 2 sensors makes
the stereo vision system very robust to non-uniform illumination, specular reflections and fast temporal illumination
changes. For example, in this stereo system design, the frame rate can be set to 25 or 30 Hz, the exposure time is set
to the maximum possible value (the frame rate period) and the sensors gain are set from the host PC to the same value
for both sensors. Another interesting property of logarithmic sensors is that contrast will be identical in areas seen by
both left and right sensors regardless of the illumination intensity on both sensors. This property is important if we
consider the stereo matching process that relies on contrast information.
