Abstract: The present disclosure relates to methods and systems for determining a state indicating whether a seat belt of a vehicle is used. A computer implemented method for determining a state indicating whether a seat belt of a vehicle is used comprises: acquiring at least one image of a portion of an interior of the vehicle; determining whether the at least one image comprises a buckle receiver; if it is determined that the at least one image comprises the buckle receiver, determining the state based on the image, and otherwise performing: extracting, from the acquired image, information related to a user of the seat belt and/or information related to a buckle of the seat belt; determining a probability of a change of the state based on the extracted information, and updating the state based on the determined probability.

Abstract: Disclosed are aspects of a vehicle that can be fitted with a visual seat belt sensor that detects whether a seat belt is worn when a seat is occupied. Such seat-belt detection systems can be implemented by using artificial neural networks or machine learning algorithms, which require a large amount of training data. A method for preparing training data includes providing an image containing a path object, such as a seat belt. Starting at a first end of the path object, a segmented line object is established, with the segmented line object including a plurality of data points and a plurality of line segments. Data points and labels, which can be respectively associated with the line segments, may be created in response to one or more user interactions at least substantially simultaneously to save time. A computer system, for instance, can implement the method.

Abstract: A computer-implemented method for determining an estimate of the capability of a vehicle driver to take over control of a vehicle, wherein the method comprises: determining at least one estimation parameter, the at least one estimation parameter representing an influencing factor for the capability of the vehicle driver to take over control of the vehicle; and determining an estimate on the basis of the at least one estimation parameter by means of a predefined estimation rule, the estimate representing the capability of the vehicle driver to take over control of the vehicle.

Abstract: A computer implemented method for determining an activity of an occupant of a vehicle comprises the following steps carried out by computer hardware components: capturing sensor data of the occupant using at least one sensor; determining respective two-dimensional or three-dimensional coordinates for a plurality of pre-determined portions of the body of the occupant based on the sensor data; determining at least one portion of the sensor data showing a pre-determined body part of the occupant based on the sensor data and the two-dimensional or three-dimensional coordinates; and determining the activity of the occupant based on the two-dimensional or three-dimensional coordinates and the at least one portion of the sensor data.

Abstract: A method for localizing a sensor in a vehicle includes using a first sensor mounted on a vehicle to capture at least one image of a moveable element of the vehicle, the moveable element having a predetermined spatial relationship to a second sensor mounted on the vehicle, the moveable element being moveable relative to the first sensor; determining spatial information on the moveable element on the basis of the at least one image; and localizing the second sensor on the basis of the spatial information by a transformation rule representing the predetermined spatial relationship between the moveable element and the second sensor.

Abstract: A computer-implemented method for determining an information on whether at least one hand of a vehicle driver cooperates with a manual steering element of a vehicle, wherein the method comprises: taking at least one image by means of at least one sensor mounted on the vehicle, wherein the at least one image captures at least a manual steering element of the vehicle; and determining, on the basis of the at least one image, an information on whether at least one hand of a vehicle driver cooperates with the manual steering element.
