Survey-Grade LiDAR and High-Precision Spatial Capture

The C1 Pro combines LiDAR sensing, inertial measurement, and SLAM positioning to create detailed three-dimensional representations while the operator moves through the environment.

• 200,000 points per second: The LiDAR system captures approximately 200,000 points per second at a typical point cloud frequency of 10 Hz. This provides dense spatial information for walls, terrain, structures, equipment, and other scanned surfaces.
• 70 m maximum range: The scanner measures from 0.1 to 40 m at 10% reflectivity and up to 70 m at 80% reflectivity. This allows the same handheld system to capture both nearby interior details and larger outdoor features.
• Centimeter-level accuracy: According to SHARE3DCAM specifications, the C1 Pro achieves relative accuracy better than 1 cm and absolute accuracy better than 5 cm. Point cloud thickness remains within 1 cm, providing accurate visualization and reliable measurement workflows.
• Survey-grade SLAM: The integrated SLAM algorithm supports continuous mapping in a wide range of environments and generates point clouds in real time. Accurate inertial sensing helps maintain trajectory stability through narrow passages, complex structures, and indoor-to-outdoor transitions.

Dual One-Inch Cameras for Detailed Colorized Point Clouds

The C1 Pro combines LiDAR measurements with high-resolution imaging, allowing captured point clouds to contain detailed color information rather than geometry alone.

• Dual 16 MP cameras: Two one-inch CMOS image sensors provide 16 MP effective pixels per camera with a pixel size of 2.4 μm. The larger sensors capture detailed imagery that improves the visual quality of colorized point clouds.
• Mechanical shutter: The cameras use mechanical and electronic shutter modes, with the mechanical shutter helping to reduce rolling-shutter distortion during movement. This is particularly useful when the scanner is carried through a site during continuous data capture.
• Spatial image synchronization: Camera exposure can be synchronized with camera POS information, helping align captured imagery with the scanner’s spatial position. This improves consistency between visual information and the corresponding LiDAR data.
• Wide scene coverage: The camera system provides broad visual coverage around the scanner, capturing color information across walls, structures, terrain, and other surfaces while the LiDAR system records their three-dimensional position.

Integrated RTK and Portable Field Design

The C1 Pro is designed to reduce the amount of additional positioning equipment required for outdoor scanning while remaining compact enough for mobile field operations.

• Built-in RTK: Integrated RTK positioning supports multi-constellation, multi-frequency GNSS positioning. The system supports seven satellite constellations and 24 frequency bands for efficient outdoor data collection and coordinate output.
• RTK accuracy: RTK positioning accuracy is 0.8 cm + 1 ppm horizontally and 1.5 cm + 1 ppm vertically. This provides a direct positioning reference for applications where scanned data needs to be linked to a geographic coordinate system.
• Lightweight construction: According to SHARE3DCAM specifications, the scanner weighs approximately 1079 g. Its dimensions of 110.5 × 140 × 313.3 mm provide a compact form factor for handheld scanning on construction sites, surveying areas, and indoor environments.
• 150-minute battery life: The 45.36 Wh, 3150 mAh battery provides approximately 150 minutes of operation. USB-C PD 30 W fast charging provides a practical charging solution for mobile field teams.
• Field-ready operation: The C1 Pro is suitable for operation from -20°C to 50°C and storage from -20°C to 60°C. Its integrated design reduces the need to mount separate positioning hardware before beginning an outdoor scan.

Open Workflow, Storage, and Professional Data Processing

The C1 Pro is designed to fit into broader 3D data workflows, from field capture to point cloud processing and CAD and BIM applications.

• 256 GB storage: The scanner features 256 GB of internal storage with expansion capabilities. This provides substantial local capacity for capturing point clouds and imagery during extended field projects.
• Wi-Fi 6 connectivity: Wi-Fi 6 supports 2.4 GHz and 5 GHz wireless communication with a specified range of up to 20 m. This enables wireless device communication and data transfer without relying entirely on physical connections.
• USB-C interface: The Type-C interface supports 30 W PD fast charging and provides a direct connection for data workflows. A TF card interface is also available for expandable storage.
• SHARE Capture: SHARE3DCAM’s SHARE Capture software is designed for on-site scanning, device connectivity, and project capture. It provides the field workflow layer for working with compatible SHARE3DCAM scanning hardware.
• PointClouds Studio: SHARE PointClouds Studio provides post-processing capabilities, including point cloud processing, CAD drawing generation, 3D Gaussian Splatting model generation, measurement, and preparation for CAD and BIM workflows. This extends the C1 Pro from field capture into further spatial data production.

Real-World Applications

The C1 Pro is designed for professionals who require accurate three-dimensional data without relying on a large stationary scanning setup.

• Construction and as-built surveying: Construction teams can scan buildings, structures, and work areas to create detailed spatial records for progress documentation and as-built reference. The combination of LiDAR, color imagery, and RTK positioning provides both visual context and measurable geometry.
• Topographic surveying: Surveying professionals can capture roads, slopes, parks, narrow passages, and other local terrain features using a handheld workflow. The 70 m maximum measurement range and centimeter-level RTK positioning support efficient collection of spatial information across smaller survey areas.
• Stockpile measurement: Mining, resource, and construction companies can scan the boundaries and surfaces of stockpiles to support volume calculations and inventory documentation. Dense point capture of approximately 200,000 points per second helps capture the shape of irregular stockpiles and their surroundings.
• Forestry surveying: Forestry teams can capture tree trunks, canopies, forest floors, and undergrowth in three dimensions. The handheld form factor allows operators to move through areas that are difficult to document using larger surveying equipment.
• Cultural heritage documentation: Surveyors and restoration specialists can continuously scan indoor and outdoor heritage structures to create detailed digital records. The combination of accurate geometry and colorized imagery supports digital archiving, restoration planning, and 3D visualization.
