Abstract
In various examples, systems and method are provided for generation of ground truth gaze data for training in-cabin monitoring systems and applications. A gaze target projector mounted to a known position inside a cabin may be used to project a gaze target onto an interior surface of the cabin. Because a beam of light may be used to produce the projected gaze target, the projected gaze target may be displayed at a projection point on the surface of the cabin interior, even if the surface at the projection point is curved, small, or an irregular shape. Three-dimensional coordinates of a projected gaze target in the cabin coordinate system may be determined and used to label image data that is captured as a projected gaze target is selectively projected onto an interior surface of the cabin and a test occupant's gaze is directed at the projected gaze target.
