Localization and Mapping Platform (LAMP) 2.0
A Berkeley Lab research team has developed the multi-sensor Localization and Mapping Platform (LAMP) 2.0 to create 3-D models of radioactive environments in real time.
The LAMP 2.0 system combines an onboard computer, light detection and ranging (LiDAR) data, visual cameras, inertial measurement unit (IMU) data, and GPS technology to collect and process environmental characteristics. LAMP 2.0 can also be designed to assemble data in a handheld configuration or on a small Unmanned Aerial Vehicle (UAV). The LiDAR sensors on the UAV are mounted horizontally, which optimizes imaging performance. This package incorporates high fidelity visual sensors and gamma-ray sensors to perform imaging and radiation detection simultaneously. This arrangement also easily integrates with a variety of other radiation sensors, including rad sensors, alpha detectors, and neutron detectors.
Gamma-ray measurements are traditionally done by hand and map only one specific kind of radiation, but the Berkeley Lab LAMP 2.0 method automates detection of radioactive materials in a scene, therefore limiting costs and complexity by offering real-time processing. The system can also be adapted to utilize UAVs to rapidly detect radiation in areas too dangerous for human activity. Onboard computer processing makes LAMP 2.0 self-sufficient in creating 3-D scene models, speeding up detection and removing the need for remote processing servers or computers.
Real-Time Simultaneous 3D Volumetric Imaging and Mapping of Gamma Ray and Neutron Sources
Berkeley Lab researchers have combined radiation detection instrumentation, data processing algorithms, and visualization software to enable simultaneous, real-time imaging of both gamma ray and neutron sources (fast and slow), adding new capability to LAMP.
Radiation detectors sensitive to gamma rays and neutrons are integrated with readout electronics that allow discriminated particles to be incorporated into real-time 3D volumetric reconstructions as two separate data streams. Using the Scene Data Fusion (SDF) conceptual framework and contextual sensors from LAMP, gamma-ray and neutron data are fused onto contextual information from the environment around the detection system. The invention is compatible with radiation detection media capable of detecting and discriminating between gamma rays and neutrons or the pairing of multiple detectors separately capable of detecting gamma rays and/or neutrons. It can be integrated into a compact, lightweight imaging platform for operation as a hand-carry device, on unmanned aerial systems, and with unmanned vehicles.
