Three-dimensional (3D) imaging technologies have considerable potential for aiding military operations in areas such as reconnaissance, mission planning and situational awareness through improved visualisation and user-interaction. This paper describes the development of fast 3D imaging capabilities from low-cost, passive sensors. The two systems discussed here are capable of passive depth perception and recovering 3D structure from a single electro-optic sensor attached to an aerial vehicle that is, for example, circling a target. Based on this example, the proposed method has been shown to produce high quality results when positional data of the sensor is known, and also in the more challenging case when the sensor geometry must be estimated from the input imagery alone. The methods described exploit prior knowledge concerning the type of sensor that is used to produce a more robust output.
