Apparatus and associated methods relate to calculating position and/or range data of object(s) in a scene external to an aircraft. A light projector (34) is configured to project, from an aircraft projector location, a collimated beam of light in a controllable direction onto the scene. The light projector (34) is further configured to control the intensity of the projected light, based on the controlled direction of the collimated beam of light. The reflected beam is detected by a camera (36, 38) located apart from the light projector (34). An image processor (44) is configured to use triangulation, to calculate position values and/or range data of the object(s) in the scene. The image processor (44) can be further configured to identify the object(s) in the scene and to produce, based in object(s) in the scene, one or more maps of the scene. The intensity of the collimated beam can be controlled based on the produced maps.
