An aerial imaging system includes a platform capable of moving through the
air, a spatial sensor, a plurality of image sensors mounted to the
platform and a computer. The spatial sensor collects position data
indicating the position of the platform. The plurality of image sensors
includes a key sensor and at least one non-key sensor. The computer
includes a storage device and a processor configured to execute
instructions comprising the steps of (i) controlling the plurality of
image sensors to collect image data simultaneously, (ii) determining the
exterior orientation of the key sensor based on the position data, and
(iii) determining the exterior orientation of at least one non-key sensor
based on the exterior orientation of the key sensor.
