摘要： Systems and methods for optically imaging a dental structure within an oral cavity by moving one or more image apertures on an arm coupled to a fixed coordinate reference frame external to the oral cavity; determining the position of the one or more image apertures using the fixed external coordinate reference frame; capturing one or more images of the dental structure through one or more of the image apertures; and generating a 3D model of the dental structure based on the captured images.

摘要： A web inspection system for analysis of a moving web of material records and stores continuous sequences of the web. The web inspection system includes a camera for recording the continuous sequence of the web, an encoder for synchronizing movements of the web with the video image being recorded, and an Image Processing System (IPS) including a real time video disk for storing the image of the web and for displaying the continuous sequence web image on a video display. The IPS is also utilized for detecting faults or features and for categorizing the faults or features detected. The entire web is recorded and the image can be viewed either interactively while the image is being recorded or at a later time. The recorded image of the web can be played back at a slower speed to allow for a more detailed inspection of the web. The sequence image can be analyzed to build a defect image database. The web inspection system can also be utilized for sorting and displaying defect information.
