摘要
本文提出了一种在三维（3D）电磁发音成像（EMA）数据上叠加腭部形状的方法。使用带有牙科印模托盘和 EMA 传感器的咬合板来获取腭部形状并记录传感器位置。然后对咬合板进行三维扫描，通过匹配扫描图像上的传感器位置和 EMA 读数中的传感器位置，将扫描的腭部映射到 EMA 数据中。在九个扬声器中，绘制的上颚与 EMA 上颚痕迹之间的平均距离约为 1 毫米，与 EMA 的测量误差相当。
Mapping palatal shape to electromagnetic articulography data: An approach using 3D scanning and sensor matching.
A method for superimposing the shape of the palate on three-dimensional (3D) electromagnetic articulography (EMA) data is proposed. A biteplate with a dental impression tray and EMA sensors is used to obtain the palatal shape and record the sensor positions. The biteplate is then 3D scanned, and the scanned palate is mapped to the EMA data by matching the sensor positions on the scanned image with those in the EMA readings. The average distance between the mapped palate and the EMA palate traces is roughly 1 mm for nine speakers and is comparable to the measurement error of the EMA.
