The image collecting parts mainly complete the conversion of the optics photograph to the image that can be treated by the computer. In this step, the pictures of teeth are shot by CCD and store in the compute at the aid of the video collecting cards. The image processing parts realize the geometric transformation, color adjusting, enhancement, measurement and some specially good effects of the collected images. And at the assist of the image processing, the more image information of dental images is exploited, so that the odontologist can diagnose more accurately.

牙科图像数字化主要完成从光学图像到计算机可处理图像的转换，为系统提供可操作的对象，其基本过程可描述为：通过CCD摄像镜头，对实物进行拍摄，由视频采集卡以信息流的形式对信号实时采集、捕捉，以帧的形式缓存，以静态的图像格式存储在计算机中；牙科图像处理部分不仅实现了图像的几何变换、色彩调整、图像增强以及一些特效，而且对牙齿病变部位进行测量，通过这些操作，能够获得更多的图像信息，提高了医生对病情诊断的科学性；牙科病例数据库部分能够浏览病人的基本信息及牙科图片，实现患者病历的添加、删除、修改等操作，建立患者牙科图像档案的图文数据库。
