3D modeling systems and methods

A method of creating a 3D model, the method comprising:

• acquiring a digital representation of a reference object;
• determining a first geometric design definition that defines a 3D reference device model configured to fit the reference object, where the first geometric design definition comprises a fit accuracy requirement that defines the fit between the 3D reference device model and the reference object, a 3D reference coordinate map of the 3D reference device model based at least partly on the fit accuracy requirement, and geometric constructs of the 3D reference device model;
• acquiring a digital representation of a target object different from the reference object;
• mapping the 3D reference device model to the target object by modifying the 3D reference coordinate map of the 3D reference device model to fit the target object;
• changing the first geometric design definition to create a second geometric design definition that defines a first 3D target device model designed to fit the target object by substituting the 3D reference coordinate map of the first geometric design definition with the modified 3D reference coordinate map;
• validating the first 3D target device model if the fit between the first 3D target device model and the target object is the same as the fit between the 3D reference device model and the reference object as defined by the fit accuracy requirement;
• adjusting the modified 3D reference coordinate map if the fit between the first 3D target device model and the target object is not the same as the fit between the 3D reference device model and the reference object as defined by the fit accuracy requirement;
• changing the second geometric design definition to create a third geometric design definition that defines a second 3D target device model configured to fit the target object by substituting the modified 3D reference coordinate map of the second geometric design definition with the adjusted 3D reference coordinate map, where the second 3D target device model is configured to fit the target object better than the first 3D target device model based on the fit accuracy requirement;
• validating the second 3D target device model if the fit between the second 3D target device model and the target object is the same as the fit between the 3D reference device model and the reference object as defined by the fit accuracy requirement;
• and
• improving the determination of the first geometric design definition using one or more learning modules, where the one or more learning modules are configured to reference one or more validated 3D target device models, where a different geometric design definition is associated with each of the one or more validated 3D target device models, and where the one or more learning modules are configured to reference one or more of the different geometric design definitions associated with the one or more validated 3D target device models.

A 3D modeling system, comprising:

• one or more data acquisition devices;
• and
• a modeling unit, wherein the modeling unit is configured to:
• process a reference object and a target object acquired from the one or more data acquisition devices, where the target object is topologically isomorphic to the reference object;
• design a 3D reference device model to fit the reference object by determining fit accuracy parameters, where the fit accuracy parameters comprise first relationships between the 3D reference device model and the reference object, and where the first relationships between the 3D reference device model and the reference object comprise a 3D reference coordinate map of the 3D reference device model;
• compare the 3D reference device model to the target object;
• determine, based on the comparison between the 3D reference device model and the target object, second relationships between the 3D reference device model and the target object;
• compare the first relationships between the 3D reference device model and the reference object with the second relationships between the 3D reference device model and the target object;
• generate a first 3D target device model by modifying the 3D reference device model based on the comparison between the first relationships and the second relationships, where modifying the 3D reference device model comprises generating a 3D target coordinate map of the first 3D target device model by morphing the 3D reference coordinate map to fit the target object;
• compare the first 3D target device model to the target object;
• determine, based on the comparison between the first 3D target device model and the target object, third relationships between the first 3D target device model and the target object;
• validate the first 3D target device model if the third relationships between the first 3D target device model and the target object are within a threshold tolerance of the first relationships between the 3D reference device model and the reference object;
• adjust the 3D target coordinate map of the first 3D target device model if the third relationships between the first 3D target device model and the target object are not within the threshold tolerance of the first relationships between the 3D reference device model and the reference object;
• generate a second 3D target device model based at least partly on the adjusted 3D target coordinate map, where the second 3D target device model is configured to fit the target object better than the first 3D target device model based on a fit accuracy requirement;
• validate the second 3D target device model if the adjusted relationships between the second 3D target device model and the target object are within the threshold tolerance of the first relationships between the 3D reference device model and the reference object;
• and
• improve the generation of the first 3D target device model using one or more learning modules, where the one or more learning modules are configured to reference one or more validated 3D target device models and the third relationships associated therewith.
