Masticatory ability is the foundation of our healthy life and it has closely relation with our motor function and cognitive ability. However, measurement of masticatory motion stably is difficult in infancy (0-5 years old) period when basic mastication ability is acquired. in this study, a safe and less invasive lip movement measurement method using an RGB-D (depth) camera has been developed for the analysis of oral functions and feeding behavior. In this report, it is evaluated that the image analysis methods and measured values of feature points by using comparison with 2 kinds of RGB-D cameras and an ultrahigh-speed 3D surface morphology imaging system. As a result, it was confirmed that the constructed system with RGB-D camera D405 has tendency of low error at the specific feature points.
