ORAL SCANNING METHOD AND ORAL SCANNER FOR REDUCING CUMULATIVE REGISTRATION ERROR AND RECORDING MEDIUM RECORDED PROGRAM FOR IMPLEMENT THEREOF

摘要

An oral scanning method is disclosed. A scanning camera of an oral scanner acquire first images for a partial tooth region of the entire tooth regions and a wide camera of the oral scanner acquires a second image for the entire tooth regions. And, a data conversion unit of the oral scanner converts the first images to first mesh data and converts the second images into second mesh data. Also, a data matching unit of the oral scanner matches the first mesh data by referring to the second mesh data, thereby reducing a cumulative matching error generated when matching the acquired data.
