    Abstract: Systems and techniques are provided for detecting drowsiness of a driver in a vehicle. In aspects, a driver is monitored by capturing an image sequence of an interior of the vehicle via a camera system. The image sequence is then analyzed to extract a characteristic pattern of the driver. An activity level of the driver is determined based on at least one of the image sequence or an output signal provided by another sensor of the vehicle. At least one of the extracted characteristic pattern and the activity level of the driver is selected as a basis for determining a drowsiness signal indicative of the drowsiness of the driver.

    Abstract: The present disclosure describes a method for occupancy class prediction, such as for occupancy class detection in a vehicle. In aspects, the method includes determining, for a plurality of points of time, measurement data related to an area and determining, for a plurality of points of time, occlusion values based on the measurement data. The method further includes selecting, for a present point of time, one of a plurality of modes for occupancy class prediction based on the occlusion values for at least one of the present point of time and a previous point of time and/or based on one of the plurality of modes for occupancy class prediction selected for the previous point of time. The method additionally includes determining, for the present point of time, one of a plurality of predetermined occupancy classes of the area based on the selected mode for the present point of time.

    Abstract: Systems and techniques are described herein for detecting a state of presence of a given object in a vehicle. In aspects, techniques include processing data received over time from various devices in the vehicle to determine a set of accumulated scores. The data includes parameters indicative of a presence or absence of a detected object in the vehicle. Further, the processing may be effective to determine a set of accumulated scores. The techniques further include determining an object-related confidence value representing a likelihood that the detected object is present in the vehicle, based on the set of accumulated scores, and then comparing the object-related confidence value to a predetermined threshold. The comparison is sufficient to detect the presence of the detected object in the vehicle if the object-related confidence value exceeds the predetermined threshold.

    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: Disclosed are techniques and apparatuses for seat belt status detection in a vehicle. In an aspect, a method includes the operations of: obtaining first infrared (IR) images and second visible light images of a seat belt region where a seat belt is expected to be visible when it is worn by a person in the vehicle; transmitting the first images to a first classifier and the second image to a second classifier; determining a first estimate of probability and a second estimate of probability that the seat belt is correctly worn, from the first and second classifiers; combining the two estimates of probability, using respective scores attributed to the first and second images, each score being indicative of the trustworthiness of the corresponding image to detect a seat belt status, to determine a combined probability; and comparing the combined probability to a predetermined threshold to determine a seat belt status.
