METHODS, DEVICES AND COMPUTER PROGRAM PRODUCTS FOR GENERATING 3D MODELS

A method of generating a 3D model may include receiving a plurality of 2D images of a physical object captured from a respective plurality of viewpoints in a 3D scan of the physical object in a first process. The method may include receiving a first process 3D mesh representation of the physical object and calculating respective second process estimated position and/or orientation information for each one of the respective plurality of viewpoints of the plurality of 2D images. The method may include generating a second process 3D mesh representation of the physical object using the plurality of 2D images, the second process estimated position and/or orientation information, and the first process 3D mesh representation of the physical object. The method may include generating a 3D model of the physical object by applying surface texture information from the plurality of 2D images to the second process 3D mesh representation of the physical object.
