1. A system for a vehicle, comprising:
an image sensor;
a processor; and
a non-transitory storage device storing instructions executable by the processor to:
capture, via the image sensor, an image of an environment of the vehicle;
detect an object in the image of the environment of the vehicle;
determine whether the object is a projected image of the object;
selectively control one or more vehicle systems of the vehicle to perform one or more actions wherein the object is not the projected image; and
authenticate the traffic sign board as a valid traffic sign board to determine that the object is not the projected image wherein the estimated depth is zero.
