Abstract
A system for a quantitative detection of a movement. The system includes a signal emitter and two signal receivers, positioned in series, along a first axis parallel to a second axis of movement of a reflective marker provided on a moving object. The reflective marker is configured to reflect a signal emitted by the signal emitter towards the two signal receivers. The two receivers have a signal reception coverage such that allows existence of a reflective marker position, on the second axis, in which the reflective marker of a given size is recognized simultaneously by the two signal receivers.
Claims9
A system for a quantitative detection of a movement, the system comprising:
- a signal emitter and two signal receivers, positioned in series, along a first axis parallel to a second axis of movement of a reflective marker provided on a moving object, wherein the reflective marker is configured to reflect a signal emitted by the signal emitter towards the two signal receivers;
- wherein the two receivers have a signal reception coverage such that allows existence of a reflective marker position, on the second axis, in which the reflective marker of a given size is recognized simultaneously by the two signal receivers;
- wherein the size Hm of the reflective marker in the second axis is calculated as a function of:
- a distance Dem between the first axis and the second axis,
- a distance Der0 between the signal emitter and the first signal receiver,
- a distance Der1 between the signal emitter and the second signal receiver,
- a signal emitting angle βe of the signal emitter,
- a signal reception angle αr0 of the first signal receiver, and
- a signal reception angle αr1 of the second signal receiver;
