  We present a test platform for visual in-cabin scene analysis and occupant
monitoring functions. The test platform is based on a driving simulator
developed at the DFKI, consisting of a realistic in-cabin mock-up and a
wide-angle projection system for a realistic driving experience. The platform
has been equipped with a wide-angle 2D/3D camera system monitoring the entire
interior of the vehicle mock-up of the simulator. It is also supplemented with
a ground truth reference sensor system that allows to track and record the
occupant's body movements synchronously with the 2D and 3D video streams of the
camera. Thus, the resulting test platform will serve as a basis to validate
numerous in-cabin monitoring functions, which are important for the realization
of novel human-vehicle interfaces, advanced driver assistant systems, and
automated driving. Among the considered functions are occupant presence
detection, size and 3D-pose estimation and driver intention recognition. In
addition, our platform will be the basis for the creation of large-scale
in-cabin benchmark datasets.
