The present invention relates to image analysis. In particular, but not limited to, the invention relates to estimating 3D facial geometry. First, images are acquired 205 of an object, typically a face. Then a first three-dimensional (3D) geometry of the object is estimated 215 based upon at least the first image. A calibration image of the object and a calibration rig 120 is acquired 405. A scaling factor is determined 420 of the first 3D geometry based upon the calibration image, a known size of the calibration rig 120 and a predetermined spatial configuration. Finally, scaling the first 3D geometry using the scaling factor. The invention also concerns a system and software. |
