Fast and Easy 3D Cave Mapping

  1. CAVE SURVEY TOOL - Records standard cave survey measurements (distance, azimuth, and inclination) in a single 3 second reading with station name entry.                     
  2. 3D LIDAR SCANNER - Handheld collection of point cloud scans of cave walls and features while traversing through cave with no extra equipment other than a single small station marker card.
  3. DESIGNED FOR CAVER EASE OF USE - Operates in a manner similar to existing cave survey methods for familiarity with a simple touchscreen GUI interface.
The Caveatron is a unique compact, handheld, electronic device for mapping caves or other underground environments. It functions as a cave survey tool, recording conventional distance, azimuth and inclination measurements and can also go far beyond that with its integrated LIDAR to capture a full 3D scan of the cave interior. It greatly speeds up the cave survey process by recording station-to-station shots in just a few seconds and performs a station-to-station 3D scan traverse in less than a minute. The user can fully interact with the device and review data with the built-in touchscreen. A USB port provides access to the stored data from a PC or Mac and is also used to charge the integrated long-life battery pack. The station measurement file is compatible with Walls Cave Mapping Software and the LIDAR scan file can be quickly processed into a standard point cloud with custom-written software. The Caveatron is designed to be easily portable, lightweight, and low cost as well as water and dirt resistant and durable enough to survive regular use in a cave..
