Abstract: An augmented reality (AR) device and a method of predicting a pose in the AR device is provided. In the augmented reality (AR) device inertial measurement unit (IMU) values corresponding to the movement of the AR device are obtained at an IMU rate, intermediate 6-degrees of freedom (6D) poses of the AR device are estimated based on the IMU values and images around the AR device via a visual-inertial simultaneous localization and mapping (VI-SLAM) module, and a pose prediction model for predicting relative 6D poses of the AR device is generated by performing learning by using a deep neural network.

Abstract: Provided are a three-dimensional (3D) camera including a wavelength-variable light source for directly measuring transmittance and a method of measuring the transmittance. The 3D camera includes, as well as a light source, a transmission type shutter, and an image sensor, and a wavelength-variable light source capable of irradiating a light with a variable wavelength without being thermally affected by the light source, the image sensor, and the transmission type shutter. The wavelength-variable light source may directly measure a change in transmittance by irradiating light toward the transmission type shutter while the 3D camera operates.
