Data Acquisition Module (DAM)

Data Acquisition Module (DAM)

Lidar mapping solution for helicopter or similar with software for creation of a colorized point cloud and generation of orto photo and oblique images.

Visimind has integrated both the Ultra Puck and Alpha Prime into a pod that can be mounted on helicopters using certified mounts. The Lidars are integrated with INS and cameras to generate an airborne mapping system. These systems include also software for processing and generation of point clouds. The data acquired can be stored and viewed in Visimind’s webtool webDPM or used in other mapping software in LAS format.

Typically, one to four cameras are integrated together with the Lidar in the pod and configured for oblique or ortograhic views. The Alpha prime Lidar has a range of up to 300 m and the typical altitude for mapping is 50-150 m. With the software package this pos is complete and ready for corridor mapping with colorized point cloud, ortophoto and oblique images.

Software

Included or as option in the package is software for
• GNSS/IMU Integration
• Point cloud generation and colorization
• Orto photo mosaic creation

Calibration

The mDAM pod comes pre-calibrated for INS, camera, and Lidar.

Point cloud

The point cloud can be generated in LAS format in the most common map
projections.
