LiBackpack Series

Handheld Mobile 3D Mapping Systems

LiBackpack 50

LiBackpack 50 enables users to accurately acquire rich 3D point cloud data quickly and efficiently. Integrating LiDAR with SLAM (simultaneous localization & mapping) technology allows for seamless real time SLAM registration and scanning capabilities in both indoor/outdoor environments The LiBackpack 50 is operable in both Handheld and Backpack modes, which offer versatility in a number of applications such as forestry and stockpile volumetrics. Real-time point cloud data streaming via the intuitive user interface to any device allows users a rapid understanding of the 3D environment. During & after scanning, users can instantly visualize data which includes path of travel, intensity and time-stamp information.

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?
