[STT34-P02] Development of a Portable Infrared Camera system for Measuring Volcanic Surface Phenomena
Keywords:a portable cameras system, airborne remote sensing, volcano observations, infrared camera, visible camera
The National Research Institute for Earth Science and Disaster Resilience (NIED) developed a portable infrared camera system, Structure and Thermal Information Capture-Portable (STIC-P) for volcano observations in March of 2020. STIC-P is a handheld portable system that can be used for observations on the ground and for handheld observations from an aircraft.
NIED has been conducting research, development and utilization of their own airborne remote sensing system for volcano observation since 1988. The first airborne spectral imaging system, the VAM-90A, was developed in 1990. In 2006, the second airborne hyperspectral sensor, the ARTS, was developed. In June 2015, the ARTS was remodeled into the ARTS-SE. ARTS-SE consists of a modified system of push-broom imaging spectrometer (ARTS) and a newly developed camera system, the Structure and Thermal Information Capture (STIC). The STIC consists of four cameras. These cameras are the two visible cameras and the two uncooled infrared cameras. The STIC specifications provide images data sets for the Structure from Motion (SfM) technique for operational volcanic observations to assess volcanic activity. In November and December 2015, we conducted observations with the ARTS-SE at the Hakone volcanoes and Asama volcanoes. These results indicated that the structure from motion (SfM) processing of image data (framed images) captured by the newly developed STIC can derive digital surface models (DSMs) and ortho-corrected images of the ground surface. We also demonstrated that the uncooled infrared camera can measure brightness temperature distributions under installed on a moving platform at approximately 270 km/h (groundspeed: 75 m/s).
Based on these results, we developed a new device that realizes the functions of STIC as a portable device, and in March 2020, a portable infrared camera system: Structure and Thermal Information Capture-Portable (STIC-P) was developed. The SPIC-P consists of three cameras. These cameras are the two visible cameras and the one uncooled infrared camera. All cameras can measure frame images or videos (30Hz) images. The STIC-P is a portable system and can realize ground-based observations and oblique observations from the sky. NIED is conducting experimental flight of mountain topography (Gifu prefecture) and experimental volcano observations (Mt. Hakone (Owakudani)) for performance evaluation of STIC-P using a helicopter. From these observation results, a geothermal distribution analysis and SfM processing will be performed to assess its accuracy.
