Abstract: Methods and apparatuses (including systems and devices), including computer-implemented methods for segmenting, correcting and/or modifying a three-dimensional (3D) model of a subject's oral cavity to determine individual components such as teeth, gingiva, tongue, palate, etc., that may be selective and/or collectively digitally manipulated. In some implementations, artificial intelligence uses libraries of labeled 2D images and 3D dental models to learn how to segment a 3D dental model of a subject's oral cavity using 2D images, height map and/or other data and projection values that relate the 2D images to the 3D model. As noted herein, the dental classes can include a variety of intra-oral and extra-oral objects and can be represented as binary values, discrete values, a continuum of height map data, etc. In some implementations, several dental classes are predicted concurrently.

Abstract: An adaptive measurement and calculation method for luminescence values of a chemiluminescence analyzer is provided. A fixed step length is adopted for continuous multi-point reading to obtain a complete correspondence diagram of detection positions and luminescence values. Two nearest luminescence values on the left and right sides of a maximum value are selected, the nearest luminescence values on both sides are connected to form a straight line, and an intersection of two straight lines is taken as an approximate maximum luminescence value. The measurement and calculation method can adapt to random positions of the detected object, and stably obtain the approximate maximum luminescence value, thus reducing increased complex hardware design and cost to confirm accuracy of the measurement position.
