Abstract
The invention relates to a method for optically sensing the surrounding area of a vehicle using at least one optoelectronic emitting/receiving device that is mounted on the vehicle. According to the method, a monitoring area located in the field of vision of the emitting/receiving device is scanned and, in addition to the monitoring area, a region of particular interest is scanned by using at least one radiation deflecting device, which is located in the field of vision of the emitting/receiving device, however, outside of the monitoring area. The invention also relates to a corresponding sensing device.
Claims24
A method for the optical detection of the environment of a vehicle comprising at least one optoelectronic transmitter/receiver attached to the vehicle, in which
- a monitored zone lying in the field of view of the transmitter/receiver is scanned, and
- a region of particular interest is scanned in addition to the monitored zone by means of at least one radiation deflection device arranged in the field of view of the transmitter/receiver, but outside the monitored zone.
A method in accordance with any one of the preceding claims, characterized in that, when scanning the field of view of the transmitter/receiver, at least part of the field of view, in particular of the monitored zone, is scanned a plurality of times via the deflection device, preferably from different directions.
A method in accordance with any one of the preceding claims, characterized in that, when scanning the field of view of the transmitter/receiver, at least part of the field of view, in particular of the monitored zone, is scanned in a plurality of different scanning planes via the deflection device, preferably from different directions.
A method in accordance with any one of the preceding claims, characterized in that a plurality of deflection devices arranged in series are used.
A method in accordance with any one of the preceding claims, characterized in that the position of the deflection device is changed.
A method in accordance with any one of the preceding claims, characterized in that the relative arrangement of a plurality of deflection devices arranged in series is changed, in particular by tilting at least one deflection device.
A method in accordance with any one of the preceding claims, characterized in that the position of the deflection device is changed, in particular automatically, in dependence on the situation.
A method in accordance with any one of the preceding claims, characterized in that the region of particular interest is displaced in dependence on information acquired by the scan by adjusting the deflection device.
A method in accordance with any one of the preceding claims, characterized in that at least one control signal is produced for the control of a vehicle device in dependence on information acquired by the scanning in particular of the region of particular interest.
A method in accordance with any one of the preceding claims, characterized in that, in particular at relatively low speeds of the vehicle, the ground is preferably scanned via the deflection device in the direction of travel in front of the vehicle.
A method in accordance with any one of the preceding claims, characterized in that, in particular at relatively high speeds of the vehicle, the scanning frequency is increased by means of the deflection device at least with respect to part of the field of view of the transmitter/receiver.
A method in accordance with any one of the preceding claims, characterized in that a scan is carried out in a plurality of scanning planes in the total field of view of the transmitter/receiver.
