摘要： A method for forming a color surface contour image of one or more teeth projects each of a plurality of structured patterns onto the one or more teeth and records image data from the structured pattern onto a monochrome sensor array. Surface contour image data is generated according to the recorded image data from the structured pattern projection. Light of first, second, and third spectral bands is projected onto the one or more teeth and first, second, and third color component image data is recorded on the monochrome sensor array. The first, second, and third color component image data is combined with color calibration data to generate a set of color values for each image pixel. The generated set of color values is assigned to the corresponding pixel in the generated surface contour image data to generate the color surface contour image. The generated color surface contour image is displayed.

摘要： A method for intraoral imaging obtains a digital image of one or more teeth and detects first and second boundaries. At each of the first and second boundaries, there is calculated a boundary ratio of mean gray-scale values for the tooth area on one side of the boundary to mean gray-scale values for background areas on the other side. The calculated boundary ratios are stored. A third ratio of the mean gray-scale values for the tooth area near the first boundary to the mean gray-scale values for the tooth area near the second boundary is calculated and stored. A vector is formed and stored that contains at least the calculated boundary ratios and the third ratio. The tooth surface is classified as either smooth or occlusal according to the stored vector. The image data is processed according to the classification and processing results are reported.

摘要： An apparatus for obtaining an image of a tooth having at least one light source providing incident light having a first spectral range for obtaining a reflectance image (122) from the tooth and a second spectral range for exciting a fluorescence image (120) from the tooth. A polarizing beamsplitter (18) in the path of the incident light from both sources directs light having a first polarization state toward the tooth and directs light from the tooth having a second polarization state along a return path toward a sensor (68), wherein the second polarization state is orthogonal to the first polarization state. A first lens (22) in the return path directs image-bearing light from the tooth toward the sensor (68), and obtains image data from the portion of the light having the second polarization state. A long-pass filter (15) in the return path attenuates light in the second spectral range.
