Abstract
A system and method for modeling three-dimensional objects such as diamonds and other gemstones. A three-dimensional finite-element model obtained by, for example, analysis of boundaries of the object in photographs taken from multiple perspectives with frontal lighting or silhouette lighting, or by analysis of structured-light photographs of the object taken from multiple perspectives, is combined with color or grayscale information obtained from photographs of the object. Enhanced or “false” color can be used to improve the viewing experience or to emphasize particular features of the object. A computer can rotate the model about arbitrary axes according to the desires of a viewer.
Claims48
A modeling system comprising:
- (a) a modeling mechanism operative to create a geometric model of at least a portion of an object;
- (b) an imaging mechanism operative to obtain at least one reflectivity image of said object, and
- (c) a mapping mechanism operative to map at least a portion of a said reflectivity image to at least a portion of said geometric model so as to provide a reflectivity model of at least a portion of said object.
A modeling method comprising the steps of:
- (a) obtaining a geometric model of at least a portion of a surface of an object;
- (b) obtaining at least one reflectivity image of said object, and
- (c) combining said geometric model and reflectivity data from said reflectivity image to obtain a reflectivity model of at least a portion of said object.
A machine readable storage medium having stored thereon machine executable instructions, the execution of said machine executable instructions implementing a method for modeling, the method comprising the steps of:
- (a) obtaining a geometric model of at least a portion of a surface of an object;
- (b) obtaining at least one reflectivity image of said object, and
- (c) combining said geometric model and reflectivity data from said reflectivity image to obtain a reflectivity model of at least a portion of said object.
