开发了一种棒状TOMBO（结合光学的薄观察模块）用于口腔内诊断。该模块由3×3成像单元组成，用于捕获不同的光信号。嵌入式功能包括立体三维监测、深度估计和组织评估。该模块集成了照明设备和图案投影仪。对几名受试者的牙齿和牙龈进行了观察。从几个单元图像中提取牙龈的三维形状。采用多元线性回归分析，估计附着龈与牙槽黏膜的边界以及黑色素的空间分布。观察到的信号被证实是有用的牙治疗。
A stick-shaped TOMBO (thin observation module by bound optics) was developed for intra-oral diagnosis. The module consists of 3×3 imaging units which are designed to capture different optical signals. Embedded functions were stereo 3D monitoring, depth estimation, and tissue assessment. Illumination equipments and a pattern projector were integrated in the module. Teeth and gingiva of several subjects were observed. 3D shape of gingiva was retrieved from a couple of unit images. The boundary between the attached gingiva and the alveolar mucosa as well as the spatial distribution of melanin were estimated using multiple linear regression analysis. The observed signals were confirmed to be useful for odontotherapy.
