Trace detection
The sensor is designed to detect an optical guide trace on the floor and to output the position
of the guide trace relative to the sensor.
The sensor can detect a light trace on a dark background or, inversely, a dark trace on a
light background.
The sensor can detect up to 6 guide traces. Each guide trace consists of a left edge (shown
in red below) and a right edge (show in green below). This edge information is output for
each detected guide trace.
When a guide trace is detected, the sensor therefore outputs two pieces of information in
the process data for each trace:
• position of the left edge of the guide trace and
• position of the right edge of the guide trace
The difference between these two edge positions is the track width.
