Application Scenarios
Open Scene Measurement
Data collection in weak/ featureless areas such as highway surveys, no-fly zones, reclamation areas, shoals, mines, and riverbank measurements.
Topographic Surveying
Meets the demand for high-precision point clouds in topographic map revision, with final results (point cloud and MESH ) meeting 1:500 topographic map requirements.
Stockpile Measurement
The real-time point cloud generated by the device can directly achieve high-precision volume measurement of stockpiles, with an accuracy of up to 1%. When used with an extendable pole, it can fully capture the 3D spatial data of stockpiles over 5 meters in height.
Forestry Survey
Handheld scanning of forest stands/ large forest areas is possible. Based on the LiDAR360 forestry module, it can quickly count the number of trees in forest stands/ large forest areas, as well as the position of individual trees, tree height, crown width, diameter at breast height, and tree species.
Underground Space Information Collection
Can be applied to the measurement of enclosed areas such as underground parking lots, power utility tunnels, air-raid shelters, shopping malls, caves, etc., providing accurate 3D spatial information for subsequent design and planning.
Construction Surveying
Pre-construction: site investigation, design review, construction plan optimization, etc. During construction: project progress monitoring, quality control, safety management, etc. Post-construction: completion acceptance, maintenance, asset management, etc.
Traffic Accident Investigation
Can quickly and comprehensively acquire point cloud and photo data from the scene and generate realistic colored point cloud and 3DGS data to facilitate accident investigation and responsibility determination.
Emergency Firefighting
Fully utilize the advantages of S7’s rapid mapping capabilities, allowing firefighters to quickly understand the site layout. The collected data can also assist disaster investigators in qualitative and quantitative analysis.
Real Estate Surveying
With its rapid and high-precision characteristics, S7 can quickly construct a 3D structure of the property, generating the original data needed for real estate surveying, providing reliable data support for real estate surveying, engineering audit settlement, renovation, and design.
