Abstract: The proposed approach is a system and method that allows a user to calculate a 3D model for each of his or her feet using a simple reference object and a mobile computing device with one or more cameras and/or one or more sensors. The mobile computing device moves around the user's feet to scan and/or capture data of his or her feet via the camera and/or the sensors. The captured sensor data is then processed by the mobile computing device to create two sets of 3D (data) point sets (also referred to as “point clouds”). These point clouds are then matched to a 3D model of an average foot to establish a correspondence between the point clouds and the 3D model. Once the correspondence is established, the mobile computing device is configured to fit one or more morphable models to the user's feet.
