A guiding system guides an autonomous movable object. The guiding system has a time-of-flight imaging system, which has a first light source to illuminate a first field of detection; and a light sensor. The light sensor detects first and second reflected light. The first reflected light has light emitted by the first light source reflected at the first field of detection. The second reflected light originates from a second field of detection illuminated by a second light source, which is independent from the first light source and is coupled to a different movable object. The imaging system differentiates between the first and second reflected light, determines a depth map of the first field of detection based on the detected first reflected light, and generates feedback. The imaging system has a motion controller that receives the feedback, and modifies a motion of the autonomous movable object based on the feedback.

Time-of-flight imaging system for autonomous movable objects

A time-of-flight depth camera includes a VCSEL array, an optical arrangement, an evaluator and a light detector having at least one detector pixel. The VCSEL array or the optical arrangement are arranged to provide different illumination patterns in a reference plane in a defined field-of-view of the time-of-flight depth camera. The light detector is arranged to detect the different illumination patterns and the evaluator is arranged to reconstruct a depth image of the field of view with a resolution of a predefined number of pixels P based on the detected different illumination patterns. A number of the detected different illumination patterns N is at least 5% of the predefined number of pixels P, preferably at least 10% of the predefined number of pixels P and most preferred at least 20% of the predefined number of pixels P.

Time-of-flight depth camera with low resolution pixel imaging

There is provided an information processing apparatus including a processor that generates a plurality of pieces of authority information for obtaining user information classified into a plurality of categories, in which the processor generates the authority information to correspond to each of a plurality of the categories.

Information processing apparatus and method for processing information

A time-of-flight camera module includes a controller, a time-of-flight detector, a laser device, and an optical unit comprising a polarization rotator arranged to rotate a plane of polarized light. The controller is configured to modulate the time-of-flight detector and the laser device in a depth sensing mode. The time-of-flight detector is configured to record depth data of a scene in the depth sensing mode by means of modulated laser light emitted by the laser device and reflected from an object in the scene. The depth data is descriptive of a distance to the object in the scene. The controller is further configured to modulate the time-of-flight detector and the polarization rotator in a surface polarization sensing mode. The time-of-flight detector is configured to record polarization data of the scene in the surface polarization sensing mode by detection light received from the object in the scene after traversing the polarization rotator.
