摘要:
The present invention provides a mobile robot configured to navigate an operating environment, that includes a controller circuit that directs a drive of the mobile robot to navigate the mobile robot through an environment using camera-based navigation system and a camera including optics defining a camera field of view and a camera optical axis, where the camera is positioned within the recessed structure and is tilted so that the camera optical axis is aligned at an acute angle of above a horizontal plane in line with the top surface and is aimed in a forward drive direction of the robot body, and the camera is configured to capture images of the operating environment of the mobile robot.

Bei der Vorrichtung und dem Verfahren zum Erfassen der Geschwindigkeit einer Objektoberfläche (3a) wird die Objektoberfläche nacheinander mit kurzer zeitlicher Verzögerung mit zwei Lichtpulsen unterschiedlicher Farbe beleuchtet. Durch entsprechende Farbfilter werden Objektstrukturen auf arrayartig angeordnete Detektorelemente abgebildet. Aus der relativen Verschiebung solcher Strukturelemente während der Verzögerungszeit wird die Geschwindigkeit der Objektoberfläche (3a) ermittelt.
摘要:
The invention provides an apparatus (1) for determining a vehicle dynamics during travel. The apparatus (1) comprises at least one imaging device (2) directed at a surface (4) relative to which the vehicle is travelling, the at least one imaging device (2) being suitable for capturing one or more images of said surface (4); a processing unit for analysing said one or more images and calculating the vehicle dynamics; wherein the apparatus (1) is provided with means for compensating for a change of distance between the imaging device (2) and said surface (4). The invention also provides a method for determining a vehicle dynamics during travel, the method including the steps of: - capturing one or more images of a surface relative to which the vehicle is travelling by means of an imaging device; - processing said one or more images and calculating the vehicle dynamics there from via a processing unit; wherein processing said one or more images include compensating for a change of distance between the imaging device and said surface. In particular, the velocity and slip angle of an automobile are determined, compensating for a varying height.
