An e-Management Method and Self-Driving Frame of on-Demand-to-Supply Robot Type using Ternary/Pair-Map

Our study on 3M&I-artifacts body looks at the (intangible) problems from the traditional Taylor-style static to dynamic (cock-pit) e-management approaches. Since the invention of pair-map (1983) at profit max, we are attempting to advance the on (moving-space)-management by pair (accelerator, brake) matrix approach. This attempt could be now characterized as the problem of profit max by pair (revenue, cost) method, and would be visualized and digitalized such as such a heliocentric vs. geocentric science as mobile “enterprise x computer” robots of SW (middle initiative) base. Finally, a static vs. moving-space automobile-like case on the pair-typed driving map is graphically given and discussed toward the shedding of classic pair-map at 2-center type since 1983.

Development of Sensing Unit “xG-1” for Visualizing Team Plays

The authors have developed "xG-1", a sports sensing unit capable of visualizing the performance and flow of play while recognizing each player in field sports such as soccer, rugby, and American football. Utilization of this sensing unit in the field of sports makes it possible to provide scientific data-driven services with the aim of transforming subjective coaching methods based on experience into new coaching methods based on data. This system consists of sensor devices and software, utilizing real-time kinematic (RTK) positioning, which is a surveying technology. Therefore, the system not only provides highly accurate positional data in real time but also visualizes the overall performance of the entire team, including formation analysis. This allows one-stop management of the overall team and individual performance, as well as efficient information management of the player's exercise load. "xG-1" can support sports businesses by providing highly extensible API and SDK and linking data among end users and systems. In the future, we aim to develop a global open data platform.

Development of Laser Scanner Units for UAV

In its i-Construction policy, the Ministry of Land, Infrastructure, Transport and Tourism has stipulated a manual for public surveying using by UAV photogrammetry with the aim of improving productivity at construction sites. However, UAV photogrammetry requires a huge amount of time to generate point cloud data from photographs, causing a problem that it is difficult to monitor the daily progress of the construction site. There is another problem that it is incapable of taking measurements except daylight hours. Against this backdrop, we have been developing laser scanner units for UAV equipped with LiDAR, IMU and GNSS receiver. Then, we clarified the error factors that are expected to affect the precision prescribed of point cloud data and summarized the requirements for the onboard equipment and the method of generating point cloud data. However, we have not yet proposed nor developed the laser scanner units as well as for generating point cloud data considering these requirements. Thus, in this paper, we developed the laser scanner units and a new method for generating point cloud data within the laser scanner units to optimize the error factors based on these requirements clarified in the existing study.

Possibility of regional revitalization by students’ IT

Recently, the number of students who can develop applications that can actually be used has increased. We thought that this power could be used for regional revitalization, we tried to connect the students and the region. As a result, we were able to create some interesting applications, some of which have become widely used in practice. For students, before going out to society, they can work on practical application development and know what kind of ingenuity is necessary to get them to actually use it. Although quality is not necessarily guaranteed in rural areas, the possibility of using the latest AI technology at a short development time and at a low cost was shown.

Development of Technology for Generating Panorama and Visualization Using Two-viewpoint Images

Research on tracking and performance analysis of athletes using video images has been actively conducted with the aim of improving athletes' competitive performance. However, when filming plays in field sports, it is difficult to capture the entire field with a single camera without filming from a specific point, such as a spectator's seat on the corner side, because the field is long sideways. Even if the entire field is captured, the players at the back of the field appear small, making analysis difficult. Other issues include the fact that since many coaches and analysts film where the play is progressing, it is hard for them to track the ball seamlessly when the position of play changes significantly depending on the position of ball. To solve this problem, we develop in this study a technology to automatically generate panoramic video images that cover the entire field by using two video cameras. Using this technology, we aim to generate panoramic images of the entire field that makes it possible to surely measure and analyze all players and the ball.

Nature versus Artifacts Body: One-Leaf Hyperboloid Type, Pair-Map Microcosm and Nested Economics

Toward digital-era, there is more increasing the portion of artifacts on the earth, and is attainable to the global environment of nature versus artifacts bodies. At the paper, we first suppose One-leaf Hyperboloid and the typical cases:Social (or enterprise) and Physical bodies as the base of nature vs. artifacts bodies. Second, the traditional pair-map is here developed, is semi-finalized at a generalization including Nash’s zone, and its 3D-like body is visually embodied as the two illustrations. Third, for a fractal(nested) mother of pair-map and its Nash’s zone, the shared equilibrium problem of 3D-type is discussed on the Trickle-down effort vs. Modern money theory (up) at Mt. Fuji type in the economic society. Finally, it is remarked that the latter might be better than the former at income distribution.
