Abstract: A calibration device for calibrating a driver assistance system. The calibration device includes a calibration board and two optically active elements, which make it possible to determine the position and/or the alignment of a motor vehicle with respect to the calibration device. The two optically active elements are attached at two mutually opposing ends of a holding device. The holding device has a longitudinal axis, which essentially extends in the horizontal direction. An acceleration sensor is attached at each of the two mutually opposing ends of the holding device.

Abstract: A method for calibrating a sensor for a driver assistance system of a vehicle. The method includes a step of outputting of a calibration signal by the sensor of the vehicle in the stationary operating state when a reference object has been placed in a position in front of the vehicle, in the step of outputting, a reference calibration value being stored, which corresponds to a calibrated state of the sensor. The method further includes a step of executing a calibration of the sensor, and/or of a further sensor in the vehicle in the stationary operating state, the calibration of the sensor and/or of a further sensor taking place using a knowledge of the position of the reference object and of the reference calibration value.

Abstract: A calibration method for a vehicle sensor. The method includes: situating a calibration device having at least one reference object in a field of view of the vehicle sensor, which is situated on a vehicle, ascertaining a first relative position of the calibration device relative to the vehicle through a measurement outside the vehicle, acquisition of the at least one reference object by the vehicle sensor, and determining a second relative position of the at least one reference object relative to the vehicle from acquisition data of the vehicle sensor, and calculating a deviation between the first relative position and the second relative position, the calibration method being terminated if the calculated deviation is already within a predetermined tolerance and a complete calibration of the vehicle sensor being carried out only if the calculated deviation is outside the predetermined tolerance.

Abstract: A method and system are provided for automatic calibration of a video camera by providing automatic perspective calculation. A calibration object detector is arranged to detect a calibration object in video data representing a scene observed by a video camera, and arranged to gather object data for the detected calibration object at a multiplicity of positions, such as three or more positions. The calibration object detector can include an automatic moving object detector and/or a static object detector. An automatic plane calculator is in communication with the calibration object detector and arranged to calculate the perspective of the camera based on gathered object data for at least one calibration object at a multiplicity of positions. The automation provided can enhance the operation of video analytics systems and reduce errors that can be introduced when an unskilled operator manually enters parameters on which the perspective is estimated.
