Résumé

The great flexibility of a view camera allows to take high quality photographs that would not be possible any other way. But making a given object into focus is a long and tedious task, although the underlying laws are well known. This paper presents the result of a project which has lead to the design of a computer controlled view camera and to its companion software. Thanks to the high precision machining of its components, and to the known optical parameters of lenses and sensor, we have been able to consider a reliable mathematical model of the view camera, allowing the acquisition of 3D coordinates to build a geometrical model of the object. Then many problems can be solved, e.g. minimizing the f-number while maintaining the object within the depth of field, which takes the form of a constrained optimization problem. All optimization algorithms have been validated on a virtual view camera before implementation on the prototype
