Imaging system

An imaging system comprising:

• at least three cameras having a common field of view, wherein each of the at least three cameras having a camera centre, and wherein the camera centres are positioned along a line,
• the at least three cameras being configured to:
• image a calibration object to generate a set of calibration object images, wherein the calibration object is located nearby the at least three cameras and in the common field of view, and
• image a scene comprising a set of distant scene position points to generate a set of position point images, and
• a processing unit configured to generate a set of calibration parameters in dependence on the set of calibration object images and the set of position point images.

A method of installing an imaging system, the imaging system having at least three cameras having a common field of view, wherein each of the at least three cameras having a camera centre, and wherein the camera centres are positioned along a line, comprising:

• installing the imaging system at a fixed location,
• controlling the imaging system to capture one or more images of a calibration object, wherein the calibration object is located nearby the at least three cameras and in the common field of view,
• controlling the imaging system to capture one or more images of a scene comprising a set of distant scene position points,
• providing the imaging system with a set of position data corresponding to the set of scene position points,
• controlling the imaging system to generate a set of calibration parameters in dependence on the images of the calibration object, images of the scene, and the set of position data.
