METHOD AND DEVICE FOR OPTICALLY DETECTING THE POSITION OF AN OBJECT BY MEASURING THE LIGHT REFLECTED BY THIS OBJECT

摘要

The inventive detection method comprises: a step (E30) over the course of which, for at least two distinct pairs of emitters (Ei) and receivers (Ri) situated on the same side with regard to the object (5), the amount of light reflected by the object (5) is measured via the receiver (Ri) when the object (5) is illuminated by the emitter (Ei); a step (E90) for calculating at least two characteristic values (K1, K2) from these measured values, and; a step (E120) for determining at least one position (x) of the object (5) by directly reading in a table (Tx) indexed by the two characteristic values (K1, K2), the contents of this table (Tx) being predetermined and fixed before the measuring step (E30).
