A method for calibrating a depth camera comprising the steps of:
S1) using a depth camera (DC) to be calibrated for acquiring a plurality of depth maps (DMS) of a physical three-dimensional reference object (PO), corresponding to different positions of the depth camera relative to the reference object;
S2) computing a three-dimensional reconstruction (3DR i ) of the reference object from said depth maps, depending on values assigned to a set of calibration parameters (SCP i ) of the depth camera;
S3) computing an error (ERR i ) between the three-dimensional reconstruction computed at step S2) and a predetermined digital model (RM) of the reference object;
said steps S2) and S3) being iterated by assigning different values to said set of calibration parameters of the depth camera; and
S4) choosing values (SCP) of said set of calibration parameters which minimize the error computed at step S3);
said steps S2) to S4) being performed by a computer. |
