Abstract: Methods and systems are described that implement determining one or more characteristics of the interior of a vehicle that lead to a reliable detection or observation of objects even if the direct line of sight between the objects and the camera is occluded. In an aspect, a computer implemented method includes the following operations carried out by computer hardware components: determining an image of an area of a cabin inside a vehicle using a sensor, the image including at least one first region representing the area reflected by at least one reflective surface provided in the cabin and at least one second region representing the area in a direct line of sight; and determining one or more characteristics inside the cabin of the vehicle based on at least one of: the at least one first region of the image; or the at least one second region of the image.

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.

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.
