A method for controlling a surface

A method for controlling a surface of interest of a part by means of a camera intended to be mounted on a carrying robot, the camera comprising a sensor and optics associated with an optical centre (C), with an angular aperture alpha and with a depth of field (PC) and defining a sharpness volume, the method comprising the following operations:

• a) loading, in a virtual design environment, a three-dimensional virtual model of the surface of interest,
• b) generating, in the virtual environment, a three-dimensional virtual model of the sharpness volume,
• c) paving, in the virtual environment, the model of the surface of interest by means of a plurality of unit models of said three-dimensional virtual model of the sharpness volume,
• d) for each position of said unit models, calculating the corresponding position, called the acquisition position, of the camera.
