| description | The present invention provides discloses an imaging apparatus (20). The imaging apparatus (20) includes an image sensor (24), which acquires an image of a scene, and a scanner (22), which includes anoptical transmitter (34), which emits a sequence of optical pulses toward the scene, and an optical receiver (48), which receives the optical pulses reflected from the scene and generates an output indicative of respective times of flight of the pulses. Scanning optics (40, 44) are configured to scan the optical pulses over the scene in a scan pattern (32) that covers and is contained within a non-rectangular area within the scene. A processor (26, 54) identifies an object (30) in the image of the scene, defines the non-rectangular area so as to contain the identified object, and processes theoutput of the optical receiver so as to extract a three-dimensional (3D) map of the object.
