Lidar (Light Detection and Ranging) processes information similar to how sonar or radar detects objects. Rather than hitting objects with a sound or radio wave, it sends a series of hundreds of thousands laser pulses per second at a target. This allows a lidar-equipped drone to collect highly accurate measurements of an object’s distance and dimensions by measuring the time it takes for each laser pulse to bounce back.
Why use LiDAR vs Traditional Methods?
1. Efficiency and Speed:
RPAS LiDAR significantly reduces data collection time compared to traditional methods, as it can cover large areas quickly from the air. This efficiency leads to faster project completion.
RPAS LiDAR allows for remote data collection, minimizing the need for personnel to work in hazardous or challenging terrain, such as steep slopes, remote forests, or construction sites.
3. High Accuracy:
RPAS LiDAR technology provides highly accurate and dense point cloud data, resulting in precise measurements and detailed 3D models. This level of accuracy can be challenging to achieve consistently with traditional surveying methods.
Site Safety Plans
LiDAR can be utilized to create site safety plans. Altohelix uses an industry leading SLAM LiDAR (GeoSLAM) to conduct interior LiDAR inspections. These 3D scans can be used to create updated floor-plans for emergency planning and building compliance
Unlike photogrammetry, which can only capture the surfaces of objects captured by an RGB camera , lidar’s laser light pulses can penetrate foliage and other obstructions. This creates levels of detail unattainable through traditional means or surveying and is ideal for capturing surfaces obscured by brush, trees, and other vegetation
By comparing the top and bottom surfaces, the software calculates the volume of the stockpile accurately. It can also provide information about the height, shape, and density of the stockpile. The results are typically presented in the form of detailed reports, 3D models, and visual representations that help in stockpile management, inventory control, and compliance monitoring.
