The traffic detection system includes an optical unit having an emitter module emitting pulses; a receiver module having a field of view including a plurality of adjacent detection channels receiving pulses reflected by an object and acquiring and converting the received pulses into a corresponding plurality of a digital signal waveforms; an image sensing module providing an image. The method comprises providing a status overlay image including the image and a visual indication on the image of an outline of the plurality of adjacent detection channels; positioning the field of view to cover the detection zone using the status overlay image; obtaining the plurality of digital signal waveforms; detecting a signal echo caused by an object in one of the digital signal waveforms at a position within the field of view; determining a location for the object using the position; storing the location for the object.

Active 3D monitoring system for traffic detection

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.

3D optical detection system and method for a mobile storage system

A method and system for determining a level of a substance in a container, the method comprises emitting one pulse from a light source in a field of illumination toward a surface of said substance in said container. A backscatter signal of said pulse is detected by an optical detector. A lidar trace is created from said backscatter signal, said lidar trace including at least one reflection peak; A surface reflection is identified among said at least one reflection peak in said lidar trace, said surface reflection being a reflection of said pulse from said surface. The surface reflection is signal-fitted to provide a fitted surface trace. A level of said substance is determined in said container using said fitted surface trace.

Optical level measurement device and method

A method for picking up objects randomly arranged in a bin using a robot having a gripper for grasping the objects using prehension feature(s) on the object. The method includes a shaking scheme for rearranging the objects in the bin when no objects are recognized, when no objects are prehensible by the gripper or when the object to be picked up is not reachable by the gripper because, for example, its prehension feature is substantially facing a wall of the bin. The method also includes a criterion for determining that a bin is free of objects to be picked up and a criterion for selecting the object to be picked up first in the bin. The method also provides for a protection mechanism against damage of the objects and the robot when a recognition technique has failed in properly recognizing the object or the prehension feature on the object.
