  • Computer vision-based technique for objective assessment of material properties in non-rigid objects
    Patent number: 6594381
    Abstract: The present invention provides a system and method for recovering material properties of non-rigid objects. The method includes, for example, the steps of: establishing a plurality of three-dimensional point correspondences of the non-rigid object in an unstressed and stressed state; from the plurality of point correspondences, generating a finite element model of the non-rigid body having initial material properties and generating a finite element strain distribution; detecting abnormal areas of the non-rigid body by comparing finite element strain levels from the strain distribution; and determining at least one material property of the abnormal areas. The system includes, for example, a general or personal computer with, optionally, one or more digital cameras and range finding devices for acquiring and processing three-dimensional correspondence data associated with the non-rigid object being an unstressed and stressed state.
