MODELLING METHOD FOR MAKING A VIRTUAL MODEL OF A USER'S HEAD - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240046593 titled 'MODELLING METHOD FOR MAKING A VIRTUAL MODEL OF A USER'S HEAD
Simplified Explanation
The abstract describes a method for creating a virtual model of a user's head using depth images. The method involves acquiring multiple depth images of the user's head in different poses, processing the images, and localizing marker points on the images. The head is then estimated by determining the yaw, pitch, and roll angles, as well as the positioning along three axes. A transformation of the head pose is performed, and the marker points are projected onto a cloud of points. The clouds of points are iteratively associated in pairs to obtain a synthesis point cloud, which is then aligned. Finally, a statistical head model is deformed using a minimization algorithm.

Original Abstract Submitted
a modelling method for making a virtual model of a user's head includes operations of: acquiring a plurality of depth images of a user's head in different head poses; processing the acquired depth images; localising on the two-dimensional images first marker points corresponding to characteristics of the head; estimating the head by estimating the yaw, pitch and roll angles of the head and the positioning of the head along three axes of a reference system of cartesian axes for each of the two-dimensional images of the depth images, performing a transformation of the head pose; projecting the first marker points located in the respective cloud of points; associating iteratively in pairs the clouds of points until obtaining a cloud of synthesis points; aligning the cloud of synthesis points; and deforming the statistical head model by means of a minimization algorithm of a predefined cost function.
