SEERS (Snapshot Spectral Imager for IR Surveillance) has developed a modular, compact and cost effective snapshot spectral imaging system in the infrared domain (0.7-14 µm wavelength). It is endowed with embedded vision and cognitive fusion capabilities. Robust visibility, robust temperature imaging, gas detection and discrimination, and spill detection enable event-driven video analysis. Breakthrough performance has been demonstrated in three relevant application scenarios: firefighting, coastal surveillance and road traffic surveillance.
Infrared (IR) imaging and sensing technology has an increasing demand from different key sectors, especially due to increasing requirements on safety and security. Moreover, US and Europe cuts in defense budgets have compelled a move towards commercial and civil applications. Surveillance and monitoring of civil infrastructures is becoming a major area of application for video surveillance equipment and services, with a $57.3bn market expected for 2020.
Isolated IR imaging solutions have given a partial response to some of these requirements through specific systems, usually at a very high cost. However, a comprehensive response to these needs with a versatile device is still missing.
SEERS project has developed a highly competitive system, in terms of cost, performance, and adaptability, for IR multispectral sensing and intelligent surveillance of a wide variety of critical infrastructures. A SWaP-C (Size, Weight, Power and Cost) modular snapshot spectral camera for the infrared domain (0.7-14um) has been developed, combining uncooled focal plane arrays (FPAs), a multi-aperture optical arrangement, computational imaging techniques, and embedded processing. The targeted range includes near infrared (NIR), short wavelength infrared (SWIR), mid wavelength infrared (MWIR), and long wavelength infrared (LWIR).
Research and development at different levels have been addressed:
Overall, SEERS approach enables robust intelligent surveillance with event-driven and smart performance. Remarkable capabilities are robustness to variable visibility conditions, gas discrimination, and fire and burst imaging with accurate temperature measurement independent on emissivity. The performance of the system has been demonstrated in three operational scenarios relative to safety and security: firefighting, road traffic surveillance and coastal surveillance.
