Abstract
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.
