Patent ID: 7020325

Claim:
A 3-dimension scanning system for a computer-aided tooth modeling, the scanning system comprising: image detecting means for extracting an image data of a tooth plaster model; moving means for changing a location and a position of the tooth plaster model measured by the image detecting means; and control means for changing and controlling the location and the position of the tooth plaster model by controlling the moving means to measure the tooth plaster model using the image detecting means; wherein the control means measures the object by using an automatic teaching method, the teaching method comprising the steps of: simulating a 3-dimension configuration measuring device on a virtual space to determine an order of measuring the tooth plaster model; generating a mesh with respect to a reference tooth model; setting a tooth to be measured; building a reasoning algorithm to automatically determine a measurement angle and a measurement location for the purpose of precisely measuring teeth having different shape and size; incorporating a real measurement result into a database to obtain an accurate measurement path; determining a measurement position including the measurement angle and the measurement location through the reasoning process of the database; measuring the tooth model by using the measurement position and the measurement path; checking whether there exists a portion which is not measured after the above measurement, changing the position of the tooth model and measuring the tooth model again if the unmeasured portion exists, and adding the result to the database.
