This research proposes a method to estimate three-dimensional coordinates of glass using a polarization camera and LiDAR. A laser beam passes through glass. Therefore, it is impossible to acquire 3D point clouds of glass when performing 3D measurement of structures with LiDAR. On the other hand, the light reflected from the glass surface has a higher degree of linear polarization. Therefore, the direction in which the glass exists can be measured by using a polarization camera. In the proposed method, a polarized camera is used to determine the glass. After the determination, point cloud interpolation is performed on the point cloud measured from LiDAR, considering the positions of the surrounding window frames. In the indoor experiment, we successfully complemented the position of the glass that could not be measured by LiDAR.

Generating animal faces using generative AI techniques is challenging because the available training images are limited both in quantity and variation, particularly for facial expressions across individuals. In this study, we focus on macaque monkeys, widely studied in systems neuroscience and evolutionary research, and propose a method to generate their facial expressions using a style-based generative image model (i.e., StyleGAN2). To address data limitations, we implemented: 1) data augmentation by synthesizing new facial expression images using a motion transfer to animate still images with computer graphics, 2) sample selection based on the latent representation of macaque faces from an initially trained StyleGAN2 model to ensure the variation and uniform sampling in training dataset, and 3) loss function refinement to ensure the accurate reproduction of subtle movements, such as eye movements. Our results demonstrate that the proposed method enables the generation of diverse facial expressions for multiple macaque individuals, outperforming models trained solely on original still images. Additionally, we show that our model is effective for style-based image editing, where specific style parameters correspond to distinct facial movements. These findings underscore the model's potential for disentangling motion components as style parameters, providing a valuable tool for research on macaque facial expressions.

The structural light method is capable of texture-free 3D measurement and has been studied for large structures. In this study, we propose a surface measurement method that simultaneously performs 3D measurement and orientation estimation using a 360° camera.
