Digital Line Scan Camera
First Claim
1. A digital line scan camera comprising:
- at least one focal plane;
at least one linear photosensitive sensor arranged on the at least one focal plane;
at least one two-dimensional photosensitive sensor arranged on a second focal plane, the at least one two-dimensional photosensitive sensor synchronously driven with the linear sensor;
an objective lens arranged a distance from the at least one focal plane;
a location measurement system comprising a satellite-supported position determination device and an inertial navigation measurement unit, the location measurement system fixedly arranged with respect to the at least one focal plane, the location measurement system configured to determine six external location parameters; and
an evaluation unit configured to calculate at least one displacement vector ({right arrow over (x)}) from data of the at least one two-dimensional photosensitive sensor, whereinthe evaluation unit is further configured to use the displacement vector ({right arrow over (x)}) to correct data of the inertial navigation measurement unit.

Abstract
Disclosed is a digital line scan camera, having at least at least one focal plane, on which at least one linear photosensitive sensor is arranged, an objective lens, and a location measurement system. The location measurement system is used to determine six external location parameters, where the location system measurement comprises a satellite-supported position determination device and an inertial navigation measurement unit. The line scan camera includes at least on two-dimensional photosensitive sensor, which is synchronously driven with the linear sensor. At least one displacement vector ({right arrow over (x)}) is calculated from the data of the minimum of one two-dimensional photosensitive sensor, and where the displacement vector ({right arrow over (x)}) is used to correct the date of the inertial measurement unit.
