SLAM LiDAR Frequently Asked Questions FAQ
1. What is the SLAM LiDAR?
SLAM LiDAR is a cutting-edge mapping device equipped with simultaneous localization and mapping (SLAM) technology and a Laser scanner. In combination they accurately capture points in 3 Dimensions so as to create a point cloud. A point cloud typically has millions of individual points, with each point having an X, Y and Z coordinates.
2. How does SLAM technology work?
SLAM technology enables realtime mapping when moving through an environment. This is achieved by combining data from various sensors, such as LiDAR, GPS, and Inertial Measurement Units (IMUs), to determine its position and map the surroundings accurately.
3. What are the key features to look for when choosing a SLAM LiDAR?
– High-precision LiDAR sensor for long range capture of points.
– Wide field of view both horizontally and vertically.
– Rate of point capture per second.
– Cameras to take colour photography so that colour rendering of the point cloud during data processing.
– User-friendly interface and processing software for intuitive operation and data analysis
4. What applications suit the SLAM LiDAR?
SLAM LiDAR is versatile and can be used in the following.
– Construction for ‘As Built’ and creating a Digital Twin.
– Open cut and Underground mining
– Urban planning and infrastructure development
– Environmental monitoring and conservation
– Archaeology and cultural heritage preservation
– Forestry and vegetation management
5. How accurate is the 3D point cloud?
A 3D point can be accurate to less than 1cm. Factors such as long distance from the LiDAR and speed of capture can affect the accuracy levels. It is beneficial to plan your trajectory of data capture and use ground control points to reduce drift.
6. Can SLAM LiDAR be used inside a building or cave?
Yes, SLAM LiDAR performs equally well indoors and outdoor environments. SLAM technology does not require a GPS signal to create a 3D point cloud. This makes it ideal for use in under ground mining applications. It also works equally as well in a bright room or a totally darkness.
