Systems and methods of acquiring the mouth in real time three dimensional images and three-dimensional measurement data of the mouth and oral structure constructs, and registers

摘要

A method and system for real time intra-orally acquiring and registering three-dimensional measurements and images of intra-oral objects and features. An intra-oral fixed global registration position is established inside the oral cavity of a dental patient, enabling real time acquiring measurements and images of intra-oral objects and features located in multiple fields of view of a measuring and imaging device positioned at various locations in the oral cavity of a dental patient, and recording global positions of the measuring and imaging device relative to the same intra-oral fixed global registration position, where the intra-oral fixed global registration position need not be in any particular field of view of measured and imaged intra-oral objects and features. Local coordinate space pixel positions of acquired and globally recorded measurements and images are registered with global coordinate space pixel positions located in global coordinate space, for forming measurements and images which are all registered with respect to the same intra-oral fixed global registration position in global coordinate space of the oral cavity of the dental patient. Accurate and precise panoramic intra-oral measurement and imaging data and information can be obtained and used in basic and advanced dental applications, whereby measurements and images from multiple fields of view are merged together for forming composite measurements and images, or maps, of the intra-oral objects and features, which can be displayed and stored for further use.
