The AIDSS Module for Aerial, Laboratory and Terrestrial Data Acquisition

The TIRAMISU Advanced Intelligence Decision Support System is an operational system proposed to Mine Action Centres worldwide for conducting non-technical surveys in humanitarian demining. The system consists of three modules, one of which is the module for data acquisition introduced and described in this study. The module has been designed, produced, improved, used and operationally tested and validated on several platforms (helicopters, RPAS and a blimp), with various sensors and acquisition units (GPS and IMU) in a variety of combinations for additional data acquisition from deep inside a Suspected Hazardous Area (SHA). For the purposes of aerial data acquisition over a SHA, the use of multiple sensors such as visible digital cameras and multispectral, hyperspectral and thermal infrared sensors are of benefit, because they display the scene in different ways. Off-the-shelf equipment and software were mostly used, but some specific equipment was developed (sensor pods, computerized imagery and data acquisition for sensors on board helicopters, computerized acquisition for sensors on RPAS, and on the blimp) and some software solutions (computer-controlled image sequence collection, IMU data acquisition, GPS data acquisition and real-time moving map visualization for navigation and acquisition, for transforming hyperspectral line scanner data into hyperspectral mosaics, and for producing hyperspectral cubes). The technical stability and robustness of the module were confirmed by operationally testing and evaluating the systems on the above-mentioned platforms and missions in several actual SHAs in Croatia and Bosnia and Herzegovina, between 2001 and 2015. The adaptation of an existing aerial hyperspectral imaging system in a low-cost setup for collecting hyperspectral data in laboratory and terrestrial field environment was also conducted. The imaging spectrometer system consists of an ImSpector V9 hyperspectral pushbroom scanner, PixelFly high performance digital CCD camera, and a subsystem for navigation, position determination and orientation of the system in space, a sensor bracket and control system. Image acquisitions indicates that this hyperspectral system has potential in archaeological and agronomic applications.
