Camera arrangement for aerial imaging

A system comprising an aerial imaging device configured to be mounted on a carrier vehicle, the carrier vehicle being configured to be traveling in a track direction and at a traveling height, the aerial imaging device being configured to acquire airborne imagery of a target area and comprising a plurality of cameras, each camera having a camera field of view, the cameras being arranged and configured to have different viewing directions in a device-transverse direction that corresponds to a cross-track direction perpendicular to the track direction, wherein:

• the cameras of the plurality of cameras have overlapping fields of view such that—in the device-transverse direction—the cameras together provide a combined uninterrupted total field of view of at least 75 degrees, in particular at least 90 degrees, which is larger than an individual field of view of each of the cameras,
• the system comprises a computing unit configured to combine images of the cameras of the plurality of cameras for providing generation of:
• a country mode composite image generated based on a combination of images from several of the cameras of the plurality of cameras and providing a field of view in device-transverse direction which is only a partial section of the total field of view, and
• a city mode composite nadir image and city mode side oblique images, wherein the city mode composite nadir image is generated based on a combination of images from several of the cameras of the plurality of cameras and provides a field of view in device-transverse direction which is only a partial section of the field of view of the country mode composite image, and wherein the city mode side oblique images provide fields of view in device-transverse direction which are only partial sections of the total field of view and have more oblique viewing directions than the city mode composite nadir image.
