Abstract: The present disclosure relates to a method for detecting a malfunction of at least one environment sensor of a motor vehicle operating while the motor vehicle passes a predefined gate region of a road network. Detection data is determined based at least in part on sensor data from the at least one environment sensor. A deviation of the detection data from reference data is determined. The reference data describes at least one object actually present in the gate region. An entry regarding a malfunction of the at least one environment sensor is stored when the deviation fulfills a predefined indicator criterion.

Abstract: A method for testing sensor devices of vehicles, including acquiring, by central processor device, first data items which are made available by a first vehicle of the vehicles. The first data items have at least one property of a positionally fixed object, which is sensed by the sensor device of the first vehicle, and a location, determined by the first vehicle, of the object, on the earth; acquiring second data items, made available by a second of the vehicles, the processor device, The second data items have the at least one property of the positionally fixed object which is sensed the sensor device of the second vehicle and a location, determined by the second vehicle, of the object on the earth; and checking the sensor devices in accordance with the first data items and the second data items.

Abstract: The disclosure relates to a method for operating a driver assistance system of a motor vehicle. The method includes detecting a first data set of sensor data measured by a sensor device of the driver assistance program. The first data set of sensor data includes missing class allocation information, wherein the class allocation information relates to the objects represented by the sensor data. The method also includes pre-training a classification algorithm of the driver assistance system while taking into consideration the first data set in order to improve the object differentiation of the classification algorithm. The method further includes generating a second data set of simulated sensor data which includes at least one respective piece of class allocation information according to a specific specification.

Abstract: A motor vehicle includes a control device and at least one lighting device which is controllable by the control device sequentially in at least two modes which illuminate surroundings of the vehicle differently. At least one camera captures at least two images of the differently illuminated surroundings of the vehicle. The at least two different images are processed by an image processing device for producing a processing result which is transmitted for control of a driver assistance system.

Abstract: An optical receiver is arranged at a location in a scene. The optical receiver includes a photo sensor configured to detect spatio-temporal modulated optical signals directed at the scene from a set of spatially dispersed optical transmitters, and to convert the optical signals from each of the optical transmitters to a corresponding electronic signal. The electronic signals can be analyzed to determine geometric properties of the location in the scene.

Abstract: A system measures reflectance in a scene. A first optical sensor is configured to measure incident energy at a location in a scene. A second optical sensor is configured to measure reflected energy from the location in the scene. The incident energy and the reflected energy are analyzed to determine a photometric property at the location of the scene.
