Vehicular driver/occupant monitoring system with enhanced learning models

A method for training a vehicular occupant monitoring system, the method comprising:

• disposing a first camera at a test vehicle, wherein the first camera views at least a seat within an interior cabin of the test vehicle, and wherein the first camera is operable to capture first image data representative of electromagnetic radiation incident at the first camera and having a first range of wavelengths;
• disposing a second camera at the test vehicle, wherein the second camera views at least the seat within the interior cabin of the test vehicle, and wherein the second camera is operable to capture second image data representative of electromagnetic radiation incident at the second camera and having a second range of wavelengths;
• wherein the first range of wavelengths of electromagnetic radiation comprises one selected from the group consisting of (i) visible electromagnetic radiation and (ii) near infrared electromagnetic radiation;
• wherein the second range of wavelengths of electromagnetic radiation comprises thermal infrared electromagnetic radiation;
• wherein the first range of wavelengths of electromagnetic radiation and the second range of wavelengths of electromagnetic radiation are different;
• disposing markers at an occupant seated at the seat of the test vehicle, wherein the markers, based on the first range of wavelengths of electromagnetic radiation incident at the first camera and the second range of wavelengths of electromagnetic radiation incident at the second camera, are (i) represented in second image data captured by the second camera and (ii) not represented in first image data captured by the first camera;
• capturing, using the first camera, first image data;
• capturing, using the second camera, second image data;
• annotating, using one or more frames of captured second image data comprising the imaged markers, locations of the markers at the occupant within one or more frames of captured first image data;
• and
• training the vehicular occupant monitoring system using the annotated one or more frames of captured first image data, wherein the trained vehicular occupant monitoring system is configured to monitor occupants of a vehicle equipped with the vehicular occupant monitoring system.

• annotating, using one or more frames of captured second image data comprising the imaged markers, locations of the markers at the occupant within one or more frames of captured first image data;
• and
• training the vehicular occupant monitoring system to classify an activity of the occupant of the test vehicle using the annotated one or more frames of captured first image data, wherein the trained vehicular occupant monitoring system is configured to classify activities of occupants of a vehicle equipped with the vehicular occupant monitoring system.
