Method and system for calibrating an image acquisition device and corresponding computer program product

A computer program product recorded on a non-transitory computer-readable medium, comprising program code instructions which, when executed on a computer, causes the computer to perform the steps of:

• emitting at least one light source pattern in an object space of said image acquisition device;
• adjusting one of said source patterns until an image pattern of said source pattern formed on a sensor of said image acquisition device exhibits a shape which centroid corresponds to a centroid of a reference pixel of said sensor, called a target image pattern;
• and
• analyzing said adjusted source pattern and estimating therefrom at least one characteristic of a pixel beam directed to said reference pixel from said adjusted source pattern.

A system for calibrating an image acquisition device comprising:

• a first light source configured to emit at least a first light source pattern in an object space of said image acquisition device;
• the image acquisition device comprising at least one sensor on which one of said emitted first light source patterns forms at least one first image pattern;
• a module for adjusting said first light source pattern until one of said first image patterns exhibits a shape which centroid corresponds to a centroid of a reference pixel of said sensor, called a target first image pattern;
• and
• an analyzing unit for analyzing said adjusted first light source pattern and for estimating therefrom at least one characteristic of a pixel beam directed to said reference pixel from said adjusted first light source pattern.
