トーワドローンサービス List of Products and Services

We offer a "Cargo Drone Service" utilizing the DJI FlyCart30 for transporting heavy cargo with drones. This service quickly responds to customer requests. It reduces disaster risks through simplified preliminary surveys and achieves cost savings through an optimal on-site operational structure. In addition to transporting materials for power line construction and slope work, as well as transporting seedlings and deer fences to mountainous areas, it can also be widely used for tasks such as extending wire for newly installed towers. 【Features】 ■ High-precision unloading performance ■ Long-distance transport with automatic flight ■ Excellent flight stability ■ Capable of flying in rainy weather ■ Built-in emergency parachute *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce "Drone Transportation." Our company offers drone transportation using drones with a maximum load capacity of 55 kg. We can assist with power-related construction, construction projects, forestry, and transportation of supplies to mountain huts, which are currently handled by human porters or helicopter transport in mountainous areas. Please consider using our drones for heavy cargo transportation, which is faster than human porters and cheaper than helicopters. □ Benefits - Reduces the risk of work-related accidents - Significantly shortens construction time compared to human porters - Reduces physical burden on workers and lowers turnover rates - Helps alleviate labor shortages □ Industry Challenges - The feasibility of operation may depend on the site environment - Limitations in time and distance due to current battery technology - High-level skills are required for the safe operation of transport drones

Benefits of Drone-Based Obstruction Tree Surveys Until now, the prediction of obstruction trees relied on the experience and intuition of skilled technicians, leading to tree felling. However, due to the lack of improved communication conditions, it has been difficult to select and fell trees appropriately. By conducting efficient surveys with drones and creating 3D models from the obtained photographic data, it is possible to identify obstruction trees on a one-by-one basis by overlaying this data with visualized microwave propagation paths. Furthermore, by simulating tree growth in 3D, it is possible to identify trees that will obstruct signals in the future on a one-by-one basis. As a result of drone-based obstruction tree surveys, identifying obstructive trees has eliminated the need for extensive felling, allowing for consideration of environmental impacts and achieving cost benefits of up to 50%.

Infrastructure such as roads, tunnels, and bridges, built en masse during the period of rapid economic growth over 50 years ago, is deteriorating as inspections have not kept pace. In 2014, the Ministry of Land, Infrastructure, Transport and Tourism mandated regular inspections every five years for bridges and tunnels over 2 meters in height through close visual inspection. However, due to issues related to personnel and budget shortages, the introduction of drones for some inspections has garnered attention. Inspections using drones include checking high-altitude facilities, solar panels, utility poles and transmission towers, inspections during disasters, and the exteriors and roofs of houses and facilities. 【Features of Infrastructure Inspections】 ■ High-quality inspection records due to improved camera performance ■ Enhanced safety due to improved drone performance ■ Ensured safety on-site by eliminating the need to access dangerous areas ■ Reliable on-site records secured through video data recording *For more details, please refer to the PDF document or feel free to contact us.

• Structural Survey

We perform "image processing" on the deliverables obtained from photographing inspection points. Based on inspection images of infrastructure facilities such as tunnels, we create layout drawings. AI analysis is conducted on images capturing cracks and free lime, and CAD conversion of crack coordinates is implemented. 【Features】 ■Significant reduction in surveying time ■Substantial labor savings in on-site work ■Ensuring safety in on-site work ■Significant improvement in measurement accuracy ■Documentation of the site ■Automation of crack detection and assessment ■CAD conversion of crack coordinates *For more details, please refer to the PDF materials or feel free to contact us.

• Structural Survey

Our company specializes in the creation of 3D models. We can realistically reproduce the shapes of equipment and surrounding environments (such as terrain), allowing for verification of the equipment from any angle, with the option to change the magnification for detailed inspection. Additionally, we are engaged in the production of new immersive content based on 3D data created from SfM (Structure From Motion) multi-view images, focusing on shape restoration. 【Features】 ■ Ability to realistically reproduce the shapes of equipment and environments (such as terrain) ■ Ability to specify desired locations, angles, and magnification for verification ■ 3D data can be used for preliminary examination of construction plans and for confirming details on-site *For more information, please refer to the PDF document or feel free to contact us.

• Structural Survey

Our company conducts surveying using UAVs (drones) as a method compliant with i-Construction. Based on numerous images taken to overlap the surveying area, we orthorectify them and generate point cloud data. This data can be utilized for volume calculations and civil engineering design. Compared to traditional surveying, we can significantly reduce the time and costs associated with measurements and data collection. 【Features】 ■ Significant reduction in surveying time ■ Major labor savings in fieldwork ■ Ensured safety in field operations ■ Significant improvement in measurement accuracy ■ Documentation of the site *For more details, please refer to the PDF materials or feel free to contact us.
