Title:
ORAL CAVITY DETECTION AND DATA PROCESSING DEVICE AND METHOD, AND ORAL CAVITY DETECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/176838
Kind Code:
A1
Abstract:
Disclosed are an oral cavity detection and data processing device and method, and an oral cavity detection system. The oral cavity detection device comprises: a probe (101), a projector (102) and a camera (103). The probe (101) is used to detect a tooth surface image in an oral cavity. The probe (101) comprises a reflector group, the reflector group comprises a plurality of mirrors which are arranged according to a predetermined positional relationship, and the mirrors are used to reflect a stripe image projected toward the reflector group onto the surfaces of teeth in the oral cavity and reflect the tooth surface image out of the oral cavity. The projector (102) is used to project a stripe image toward the reflector group of the probe (101), and the reflector group reflects the stripe image toward the surfaces of teeth. The camera (103) is used to acquire a reflected tooth surface image containing a stripe pattern from the reflector group of the probe (101). By means of such a device, tooth surface images of a plurality of surfaces and an accurate relative position relationship therebetween can be obtained, and errors in the process of image mosaicking can be reduced, while the frequency of moving the probe (101) is reduced.
