Patent number: 8446571Abstract: A device for recording a geometry of an environment of a device in a detection field with the aid of laser scanning may include a laser beam controlled by an oscillating micromechanical mirror. The detection field is specifiable in the vertical and horizontal directions by adapting an amplitude of oscillation of the micromechanical mirror. Driver-assistance systems are used for tasks both in the near field, such as a parking function, and in the distant field of the vehicle, such as a distance control or the detection of obstacles on the roadway. If the amplitude of the oscillation of the micro-mirror is then reduced in the horizontal direction and/or vertical direction, the spatial resolution for the reduced detection range is improved. Moreover, the higher intensity of the laser radiation impinging on the smaller detection region improves the signal-to-noise ratio of the detected signal.Type: GrantFiled: November 17, 2009Date of Patent: May 21, 2013Assignee: Robert Bosch GmbHInventors: Reinhold Fiess, Sascha Steinkogler
