The invention relates to a vehicle camera system 200 for determining a geometric parameter in an image. The vehicle camera system comprises a first camera 202, a second camera 204 and a processing unit 208. The first camera is configured to capture a first image, wherein the first image is captured in a first orientation of the road with respect to the direction of travel of a vehicle100. The second camera configured to capture a second image,wherein the second image is captured in a second orientation of the road with respect to the direction of travel of a vehicle. The processing unit configured to determine a characteristic of the road in the second image and to apply the determined characteristic to the first image, and to determine a geometric parameter in the first image using the detected characteristic of the road 102. The first image may contain a further vehicle 108, and the characteristic may be a horizon and the geometric parameter is a height above the horizon. The system may be used to determine speed and/or distance of the further vehicle behind the system based upon the horizon characteristic in front of the system.
