Abstract
A method for acquiring tracking points belonging to a trajectory of a target object in motion, includes: emitting a radiation towards the target object; receiving a reflection of the radiation from the target object in respective fields of view of each detection zone of a network of detection zones; processing the reflection by determining distances separating the target object from an origin point by measuring a time of flight of the radiation in each detection zone; determining a degree of coverage of each detection zone; and estimating, based on the distances and on the degree of coverage of each detection zone, a position of a tracking point corresponding to a position of an extremity of the target object inside a respective detection zone chosen in a direction of motion of the target object.
