Abstract

The present disclosure provides a system 102 and a method 400 for estimating the facial measurements of a user in a vehicle. The method 400 comprises receiving 402 a first coordinate, a second coordinate, and a third coordinate. Furthermore, the method 400 comprises determining 404 that a field of view (FoV) of the second sensors is moved at a certain angle and determining 406 that the second coordinate is updated. The method 400 further comprises transforming 408 the updated second coordinate into the third coordinate and modifying 410 the third coordinate. The method 400 further comprises mapping 412 the modified third coordinate onto the first coordinate and generating 414 a three-dimensional (3D) coordinate map. Finally, the method 400 comprises estimating 416 the facial measurements of the user.Therefore, the present disclosure reduces the dependence on fixed sensor settings and improves the efficiency of determining user facial measurements in relation to vehicle coordination.
