Abstract

A processing system and method for producing formatted information related to appliances of an appliance chain. This appliance chain includes at least one image-capture appliance and/or at least one image-restitution appliance for capturing and/or restituting an image on a medium. The system and method produce formatted information related to geometric distortions of at least one appliance of the chain. Fixed characteristics of the appliances and/or variable characteristics depending on the image can be taken into account. The fixed characteristics and/or the variable characteristics can be associated with one or more characteristic values, especially the focal length and/or the focusing. Then, measured formatted information related to the geometric distortions of the appliance are produced from a measured field. The system and method are applicable to photographic or video image processing, in optical devices, industrial controls, robotics, metrology, etc.
