Abstract: A system having a camera to capture a scene image of a scene having an object as viewed from a perspective of an operator through a windscreen; a computer vision circuit to identify an object image corresponding to the object in the scene image captured by the camera; a marker generator circuit to generate a marker indicative of the identified object image and to determine a marker position in the operator's line of sight between the object and the operator; and a screen to display the generated marker in the marker position to appear associated with the identified object as viewed from the perspective of the operator through the windscreen. Also, methods for marking objects.
