Abstract
In various examples, one or more interior or occupant monitoring sensors may be calibrated using one or more display units (e.g., a projector, LED panel, laser robot, heads-up display) that can actively project or display a unique visual pattern and change one or more attributes of the patterns (e.g., shape, color, brightness, size, frame rate, perspective, etc.) without moving the one or more display units. The present techniques may be utilized to iteratively calibrate a sensor using a dynamic visual pattern with one or more visual attributes that vary from iteration to iteration, and/or to interleave different visual patterns in a common region of an overlapping field of view shared by multiple sensors.
