DIGITAL IMAGING SYSTEM FOR AIRBORNE APPLICATIONS |
摘要 |
An aerial imaging system has an image storage medium locatable in an aircraf t, a controller that controls the collection of image data and stores it in the storage medium and a digital camera assembly that collects image data from a region to be imaged. The camera assembly is mounted to a pre-existing extern al step mount on the aircraft. An inertial measurement system (IMU) is fixed in position relative to the camera assembly and detects rotational position of the aircraft, and a GPS receiver detects absolute position of the aircraft. The camera assembly includes multiple cameras that are calibrated relative t o one another to generate compensation values that may be used during image processing to minimize camera-to-camera aberrations. Calibration of the cameras relative to the IMU provides compensation values to minimize rotational misalignments between image data and IMU data.
