Article
In this study, we develop a sensor terminal with multiple and various sensors named sensor pod, which collects various environmental information at a construction site. The sensor pod is equipped with a 3D-LiDAR and a vibration sensor, which can be used to predict the surrounding hazards and evaluate the ground stiffness. In this paper, we introduc...
Article
This paper presents a retrofit backhoe remote control system that is inexpensive, compact, and easy to install. The system consists of a remote control system using a teleoperation system embedded by a construction machinery manufacturer and a small robot arm, and a remote sensing system using a multi-core microcomputer.
Preprint
3D LiDAR sensors are indispensable for the robust vision of autonomous mobile robots. However, deploying LiDAR-based perception algorithms often fails due to a domain gap from the training environment, such as inconsistent angular resolution and missing properties. Existing studies have tackled the issue by learning inter-domain mapping, while the...
Preprint
Generative modeling of 3D scenes is a crucial topic for aiding mobile robots to improve unreliable observations. However, despite the rapid progress in the natural image domain, building generative models is still challenging for 3D data, such as point clouds. Most existing studies on point clouds have focused on small and uniform-density data. In...

Automatic analysis of our daily lives and activities through a first-person lifelog camera provides us with opportunities to improve our life rhythms or to support our limited visual memories. Notably, to express the visual experiences, the task of generating captions from first-person lifelog images has been actively studied in recent years. First...
Article
Terrain classification is critically important for Mars rovers, which rely on it for planning and autonomous navigation. On-board terrain classification using visual information has limitations, and is sensitive to illumination conditions. Classification can be improved if one fuses visual imagery with additional infrared (IR) imagery of the scene,...
Article
This paper presents several multi-modal 3D datasets for the problem of categorization of places. In this problem. a robotic agent should decide on the type of place/environment where it is located (residential area, forest, etc.) using information gathered by its sensors. In addition to the 3D depth information, the datasets include additional moda...
Article
Gait-based person recognition has received an increasing amount of attentions for monitoring and surveillance applications. One of issues in gait recognition is that it is difficult to recognize people with high performance, in case that the resolution of captured images is too low. To deal with this problem, this paper presents SFDEINet, which use...
Article
Semantic place categorization, which is one of the essential tasks for autonomous robots and vehicles, allows them to have capabilities of self-decision and navigation in unfamiliar environments. In particular, outdoor places are more difficult targets than indoor ones due to perceptual variations, such as dynamic illuminance over 24 hours and occl...
Article
In this paper, we present a near future perception system named “Previewed Reality”. We integrate an immersive VR display, a stereo camera and a dynamic simulator into our informationally structured environment(ISE) platform for service robot. In ISE, a human wearing the immersive VR display can see the next possible events as virtual images overla...
Conference Paper
To provide daily-life assistance appropriately by a service robot, the management of houseware's information in a room or a house is an indispensable function. Especially, the information about what and where objects are in the environment are fundamental and critical knowledge. We can track housewares with high reliability by attaching markers suc...
Article
In this paper, we present a system to register housewares in a room to database automatically to maintain an informationally-structured environment. We assume that housewares requested by a user are likely to be appeared in an egocentric vision of the user. The proposed system captures the egocentric vision by a smart glass, detects multi-class obj...
Article
This paper proposes a new concept of "fourth-person sensing" for service robots. The proposed concept combines wearable cameras (the first-person viewpoint), sensors mounted on robots (the second-person viewpoint) and sensors embedded in the informationally structured environment (the third-person viewpoint). Each sensor has its advantage and disad...
Article
Service robots, which co-exist with humans to provide various services, obtain information from sensors placed in an environment and/or sensors mounted on robots. In this paper we newly propose the concept of fourth-person sensing which combines wearable cameras (first-person sensing), sensors mounted on robots (second-person sensing), and distribu...
