The LISA-M Human-Centered Intelligent Vehicle Test Bed

  OBJECTIVES

The LISA-M is the initial test bed for several experiments for the occupant posture estimation investigation. Situated in the laboratory, prototype vision systems are developed on the LISA-M with readily available AC power, camera rigging bars and realistic seat, dash, and ceiling dimensions.

 

  CAMERAS

Multiple color rectilinear cameras are placed around the occupant in the passenger seat for comprehensive view of the occupant. Multi-perspective imagery of the occupant is one sensor modality evaluated in the investigation of an vision-based occupant posture estimation system.

Trinocular stereo camera and real-time stereo computation software makes readily available stereo depth information of the scene. Stereo vision is another modality under investigation for the occupant posture problem.

The thermal long-wavelength infrared camera captures emitted electromagnetic energy. This modality is most effective when the objects of interest in the scene have similar temperatures and emissivity characteristics across the range of possible object variations, such as human occupants.  

The omnidirectional camera offers the advantage of a complete 360 degree view of the surroundings.
