Individual detecting method for given observation zone, involves masking beams of cells based on different combinations to provide information to calculation unit for localizing individual in position and during displacement

摘要

The method involves arranging reduced number of identical infrared sensors (1) centered on a given observation zone, where each sensor includes a specified number of cells. Beams of the cells are masked based on different combinations to provide information to a calculation unit (4) for localizing an individual in a position and during displacement, where the cells are triggered angularly. An independent claim is also included for a system for implementing an individual detecting method.
