AIRCRAFT SENSOR SYSTEM SYNCHRONIZATION

A method, apparatus, system, and computer program product (1222) for operating an aerial imaging system (200). A first altitude (226) of a first aircraft (204) is determined, by a computer system (210), using first images (212) of a key point (220) generated by the first aircraft (204) during a flight and stereo depth triangulation (224). The first altitude (226) is compared with a second altitude (230) of a second aircraft (206) determined by the second aircraft (206), by the computer system (210), to form a comparison (232). An offset (238) between the first altitude (226) and the second altitude (230) is determined, by the computer system (210), using the comparison (232). At least one of the first altitude (226) or the second altitude (230) is adjusted based on the offset (238). A plurality of images of a region from the first aircraft (204) at the first altitude (226) and from the second aircraft (206) at the second altitude (230) is obtained.
