What is a 3D Lidar Mobile Survey?
3D LiDAR Mobile Survey all about of mapping is the process of collecting geospatial data from a mobile vehicle with extranal built Leica LiDAR remote sensing system on the top of the roof easily mounted.
LiDAR has significant role in it due to high accuracy and data capture 80 Meter wide range in both side LHS & RHS. It can scan more than 100 kms of the roads in a per day and the data is high accuracy capture upto 5mm accuracy.
A 3D LiDAR Mobile Survey is a cutting-edge geospatial data collection method that utilizes Light Detection and Ranging (LiDAR) technology mounted on a mobile platform such as a vehicle. This technique captures highly accurate three-dimensional data of physical environments in real-time by emitting laser beams and measuring their return time after hitting a surface. The process generates dense point clouds—collections of data points in 3D space—that represent the shapes and spatial details of the surveyed area.
How 3D LiDAR Mobile Surveys Work
- LiDAR Sensor: Emits laser pulses and measures the time it takes for the light to reflect back, calculating the distance to the surface.
- Global Positioning System (GPS): Provides precise location information of the mobile platform.
- Inertial Measurement Unit (IMU): Tracks the motion and orientation of the sensor for accurate mapping.
- Data Processing: The collected data points are processed into 3D models or maps using specialized software.
Advantages of 3D LiDAR Mobile Surveys
- High Precision: Captures detailed measurements with millimeter accuracy.
- Efficiency: Gathers data over large areas quickly compared to traditional surveying methods.
- Versatility: Effective in various environments, including urban settings, forests, and rugged terrains.
- Safety: Allows data collection from a distance, reducing risks for surveyors in hazardous locations.
- Real-Time Visualization: Enables immediate assessment of the data collected on-site.
