3D optical detection system and method for a mobile storage system
First Claim
1. A mobile storage comprising:
- a mobile storage unit extending along a longitudinal axis, having a detection side;
an opposing component extending substantially parallel to the longitudinal axis, having an aisle side facing the detection side of the mobile storage unit, the opposing component being one of a wall, a second mobile storage unit and a stationary storage unit;
the mobile storage unit being movable between a closed position wherein the detection side of the mobile storage unit and the aisle side of the opposing component are juxtaposed and an open position wherein the mobile storage unit and the opposing component are spaced-apart and a longitudinally extending aisle is defined therebetween;
the mobile storage having at least one detection module having an optical pulse emitter and an optical detector both provided at an end of one of the detection side of the mobile storage unit and the aisle side of the opposing component, facing the aisle, the optical pulse emitter emitting a light pulse in a field-of-illumination, the optical detector detecting a reflection of the light pulse in a field-of-view, the field-of-illumination and the field-of-view being adapted to at least partly overlap and to cover at least a portion of a width of the aisle.

Abstract
A mobile storage having a mobile storage unit having a detection side; an opposing component having an aisle side facing the detection side; the mobile storage unit being movable between a closed position and an open position wherein an aisle is defined; at least one detection module having an optical pulse emitter and an optical detector both provided at an end, facing the aisle, the optical pulse emitter emitting a light pulse, the optical detector detecting a reflection of the light pulse. An object detection method for a mobile storage comprising comparing a temporal reflection signal to a background temporal reflection signal to detect the presence of an object; and indicating a status of the aisle to be presence of an object if the object is detected to be present.
