Abstract
A camera device for a vehicle for 3-D environment sensing includes at least two camera modules having at least partly overlapping sensing ranges, a camera control unit, an evaluation unit and a point light projector. The point light projector is arranged and configured in such a way that the point light projector projects a light pattern of measurement points into the vehicle environment. The at least two camera modules are arranged and configured in such a way that at least part of the projected light pattern is imaged in the overlapping sensing range. The evaluation unit is configured to determine the 3-D position of measurement points in the vehicle environment from image data captured with the at least two camera modules. The point light projector is configured to produce a series of “pseudo-noise patterns” as the light pattern, the “pseudo-noise patterns” being projected into the vehicle environment in temporal succession.
