Kudan's Visual SLAM Technology Adopted in log build's Next-Generation Construction Management App 'Log Walk'
Kudan's commercial-grade Visual SLAM technology has been integrated into 'Log Walk', a construction management application by log build. By simply walking through a site with a standard 360-degree camera, users can generate spatial data for AI verification and remote monitoring, addressing severe labor shortages and improving productivity in the construction industry.

Kudan Inc. (Headquarters: Tokyo, CEO: Daiu Ko, hereafter "Kudan") announces that its Visual SLAM (Simultaneous Localization and Mapping) technology has been adopted in the next-generation "Log Walk," a service fully launched by log build Inc. (Headquarters: Kanagawa, Representative Director: Kenichi Nakabori, hereafter "log build"), a company promoting digital transformation (DX) in the construction industry.
Construction site management traditionally relies on site supervisors physically visiting locations to visually inspect progress, quality, and safety. However, worsening labor shortages have increased the number of sites managed per supervisor, making it difficult to monitor all locations with sufficient frequency.
Furthermore, traditional recording methods using photos or standard 360-degree cameras have limitations; it is difficult to accurately determine the exact location and orientation of an image within a site and view it as spatially continuous information. This makes it challenging to review specific areas from desired angles later, often necessitating repeat site visits.
With this new service, a photographer simply walks through the site holding a commercially available 360-degree camera. Kudan's Visual SLAM technology estimates the camera's trajectory and the 3D structure of the surrounding environment, providing data that spatially connects the entire site. This allows construction sites to be saved and reviewed not just as simple photo or video logs, but as spatial data containing precise location and viewpoint information. As a result, supervisors can inspect sites from any angle remotely, as if they were actually there. By receiving automated AI assessment results alongside this spatial data, supervisors can grasp progress and quality with less personnel and time.
Construction sites are particularly challenging environments; materials, scaffolding, workers, and heavy machinery move daily, causing the same location to look vastly different over time. Mixed indoor/outdoor environments, lighting changes, narrow spaces, occlusions, and repetitive structures make stable position estimation from images alone highly difficult. Kudan's commercial-grade Visual SLAM algorithm enables stable localization even in these highly variable real-world conditions.
[Main Benefits of the Service]
- Drastic Reduction in Recording Time: No need to set up cameras at fixed points or perform complex measurements. Simply walking the site captures spatial data with location tracking.
- Enhanced Remote Management Quality: By spatially organizing video data via Visual SLAM, remote managers can view specific details from free angles, improving the accuracy and efficiency of site comprehension.
- Operational Efficiency: The ability to review necessary areas later within the spatial data reduces the need for physical site visits, speeding up decision-making and improving time efficiency.
- Practical Operation with Standard Cameras: Enables easy data acquisition using off-the-shelf 360-degree cameras without relying on expensive, dedicated measurement tools, making it easy to deploy on-site.
- Automated Checking of Drawings, Safety, and Quality: A checking AI automatically compares the acquired spatial data against blueprints, construction guidelines, and safety regulations, automating parts of the inspection previously done manually.
- Turning Site Operations into Data Assets: Linking the spatial data with the standardized checking infrastructure of log build's KPO service, "Remote Daikou," continuously evolves construction quality management into reproducible digital assets.
Achieving high-precision localization using only an inexpensive 360-degree camera in dynamic construction sites is a significant technical challenge. While general open-source (OSS) SLAM technologies show certain performance levels in research environments, they struggle to maintain stability in actual construction sites where lighting, structures, and dynamic objects change simultaneously.
Kudan's commercial-grade Visual SLAM possesses high robustness designed for such real-world applications, balancing simple recording via standard cameras with practical spatial data generation. This technology goes beyond mere recording, acting as a foundation to convert footage into usable spatial information, greatly contributing to the practical realization of this service.
The commercialization of this service is the result of repeated on-site verification and improvement, combining log build's practical construction expertise with Kudan's commercial Visual SLAM. log build, led by Representative Director Kenichi Nakabori—who has 30 years of industry experience and hands-on site management—has transformed ecomo, an architectural firm in Shonan, Kanagawa, into a leading Smart Builder. By combining site understanding with spatial recognition technology, both companies have optimized a platform robust enough for daily changing construction environments.
Moving forward, log build positions the full-scale deployment of this service to large-scale architectural and civil engineering sites managed by general contractors as its next strategic phase.
Kudan provides the foundation for accurately understanding and utilizing physical spaces digitally through advanced spatial recognition technology. Kudan will continue to accelerate Construction DX by offering technologies that support the acquisition, visualization, and utilization of site data, addressing industry challenges such as labor shortages, productivity enhancements, and advanced remote management.
Highly accurate digitization of site spaces also serves as the foundation for physical AI and robotics. By providing spatial perception technology that enables machines to understand the real world and act autonomously, Kudan contributes to the further automation and advancement of real-world industries, including construction.
The impact of this disclosure on current financial performance is already reflected in the earnings forecast, and no additional impact is expected at this time. Should any events requiring disclosure occur in the future, they will be promptly announced.
