Production of a model of 4-dimensional articulatory organ and its application to cleft palate speech

利用三维内窥镜的模式投影成像，可以产生腭咽的范围图像。在瞄准镜的尖端安装了直径2mm的镜头，使我们能够在15mm的距离上产生清晰的图像，并对深度超过30mm的图案进行成像。经精度验证，该系统生成的距离图像的标准误差为0。4%。

Range images of the velopharynx were able to be produced from the images of 3-D Endoscope with pattern projection. Installation of lens of 2mm in diameter at the tip of the scope enabled us to produce a clear image at 15mm distance and to image the pattern with the depth over 30mm. As a result of verification of its accuracy, range images produced by this system had a standard error of 0. 4%.
