Technological innovation drives engineering data to be 'more practical,''more intuitive,' and 'smarter.'

Through the application of cutting-edge technologies such as AR/MR, 360 panoramic imaging, SLAM, point cloud, 3DGS, IoT, AI, 3D visual algorithms, and 3D image algorithms, and based on our proprietary BIM underlying development, we support domestic BIM data formats, domestic processors, and domestic databases within trusted computing platforms. We provide private computing and storage solutions, enabling clients to establish integrated platforms that fully support business needs in a trusted environment, ensuring compliance with national security standards and meeting data protection requirements.

This technology allows the construction management team to view the site in real-time, track construction progress, and perform quality inspections. Unlike traditional photography, 360 panoramic images provide a full environmental perspective and support comparison with design drawings, helping to identify deviations and issues promptly, ensuring the project progresses as planned. With 360 panoramic recording, every change on the construction site is precisely captured, providing reliable data for future decision-making. Additionally, integrated with the Yijian® 360 Pose Recorder and other smart hardware developed by Yijian Technology, it features a professional PDR (Pedestrian Dead Reckoning) positioning algorithm, offering accurate indoor and outdoor positioning based on GPS or pedestrian movement.

IoT technology plays a pivotal role in the operation and maintenance (O&M) phase of buildings. By integrating smart sensors and devices with building management systems, IoT enables real-time monitoring of key parameters such as temperature, humidity, and air quality within the building. This data provides O&M teams with real-time environmental monitoring and facility management support, ensuring accurate handover of property documentation and assisting property managers and maintenance teams with daily asset and equipment inspections. The result is faster repairs and efficient digital O&M management, driving long-term ESG development.Currently, we support IoT sensor data integration via protocols such as HTTP, WebSocket, and MQTT, along with a 3D spatial mapping tool based on BIM models.

Using panoramic capture devices or handheld LiDAR equipment, data such as photos, videos, or specific formats can be collected to generate 3D Gaussian splat data through NeRF and 3D Gaussian function methods. This serves as a critical data foundation for BIM model repair and reconstruction. In new construction or renovation projects, point cloud data can act as a precision verification tool for BIM models. This 'Point Cloud + BIM' verification method enhances construction accuracy, reduces errors, and prevents costly rework and resource waste.At present, Yijian supports the import of point cloud data from both domestic and international hardware, with compatibility for multiple file formats, including PLY, PCD, RCP, e57, and RCS.

Point Cloud Navigation | Real-Scene Reconstruction as the First Step in Reverse Modeling

Point cloud technology generates a 3D scene that accurately reflects the actual state of a construction site or existing building. This provides an authentic and detailed 3D environment for teams to visualize and analyze. The point cloud data can then be converted into editable geometric models for further refinement.

3DGS + BIM Comparison | Deviation Detection and Verification

By overlaying 3DGS point cloud data with the BIM model from the design phase, deviations can be quickly identified. This process aids in the calibration and repair of BIM models, ensuring accuracy throughout the project lifecycle.
