Abstract
An electronic device and method of preservation of geometry details in tracked meshes is provided. A set of three-dimensional (3D) scans and a sequence of tracked meshes of an object of interest are acquired. The sequence of tracked meshes comprises a set of tracked meshes which temporally corresponds to the set of 3D scans. Based on differences between the set of tracked meshes and the set of 3D scans, a set of displacement maps is generated. A plurality of vectors is computed, each of which includes surface tension values associated with mesh vertices of a corresponding tracked mesh. Based on the set of displacement maps and a corresponding set of vectors, a neural network is trained on a task of displacement map generation. The trained neural network model is applied on the plurality of vectors to generate displacement maps. Each tracked mesh is updated based on a corresponding displacement map.
