LiBackpack C50

LiBackpack C50 is an advanced SLAM-based 3D mapping system which integrates LiDAR and 360° imaging technologies to produce true color point clouds. Functional in both handheld and backpack modes, the LiBackpack C50 is a flexible mobile laser scanning solution for indoor and outdoor applications. Users can opt for a LiDAR-only solution when colorized point clouds are not required.

LiBackpack 50 for Forestry: Finding DBH Values

As part of our LiDAR in Forestry applications series we investigated the accuracy of diameter at breast height (DBH) measurements extracted from LiBackpack data using LiDAR360’s TLS Forestry Module. We found DBH values fitted in LiDAR360 had a mean absolute error (MAE) of...

LiBackpack D50

LiBackpack D50 is GVI's premium mobile mapping system, comprising of two Velodyne VLP-16 LiDAR sensors. The D50 is able to capture twice as many points which, in turn, further assists our SLAM algorithm in providing both accuracy and scanning robustness. By including dual-laser sensors, 3 dimensional features within the point cloud are more well-defined compared to other mobile mapping systems. All of this is provided in a durable, lightweight housing - giving users the ability to scan vast areas for up to 2 hours.

• Real time SLAM registration

• Process data as you scan

• Real time point cloud visualization

• Scan both outdoor/indoor environments

• Visualize trajectory in real time to ensure full scan coverage

• Post-process data in LiDAR360

Urban Power Line Management

A previous article showcased GVI solutions using UAV LiDAR for high-voltage transmission line survey. We now turn to another question, what about using LiDAR to inspect power distribution lines in urban neighborhoods?
