SEERS Report Summary

Project ID: 645114
Funded under: H2020-EU.2.1.1.6.

Periodic Reporting for period 1 - SEERS (Snapshot spEctral imagEr for cost effective IR Surveillance)

Reporting period: 2015-02-01 to 2016-01-31

Summary of the context and overall objectives of the project

SEERS proposes a breakthrough approach to multispectral imaging in a broad band of the infrared domain. Video surveillance for safety and security is targeted for demonstration.
The overall objective of SEERS project is to develop a compact snapshot multispectral imaging system in the range 0.7-14 µm wavelength based on three uncooled and low cost FPA technologies (PbSe, CMOS-based microbolometers, CMOS).
Firstly, a snapshot multispectral imager in the IR domain will be developed. Secondly, an embedded approach will be adopted for image reconstruction, cognitive image fusion, video pre-processing and event-driven operation. Thirdly, the benefits of a novel video analytics solution (VAS) for smart networked operation will be demonstrated in terms of performance and persistence, thanks to multispectral imaging.
With this aim, research and development at different levels will be addressed:
• Microbolometer (FPA) re-design adapted to multi-aperture imaging requirements
• Development of multi-aperture sensor arrays for multispectral and super-resolution imaging
• Embedded processing for: image reconstruction based on computational imaging, cognitive image fusion, spectral measurements, and video pre-processing
• Persistent video analytics based on pre-processed multispectral video
Overall, SEERS approach will enable robust intelligent surveillance with event-driven and smart performance. Remarkable capabilities will be robustness to variable visibility conditions (e.g. fog, rain, fumes), gas discrimination and level determination, spill detection, fire and burst imaging with accurate temperature measurement. Demonstration will be addressed in real operational conditions for two different scenarios: coastal and tunnel surveillance.

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

The first year of SEERS project has been devoted to the following main activities:
• A detailed specification of end user needs, describing scenarios and current needs in terms of e.g. types of targets, dimensions, visibility and operational conditions
• The setup and running of laboratory tests for prototyping the measurement of gas concentration and temperature, as well as the selection of spectral bands for these purposes and oil spill detection
• First tests in prototyping super resolution and multi spectral reconstruction algorithms suited to infrared images.
• Optical design for multi aperture imaging in a broad IR range
• Definition of the electronic architecture, comprising interfaces and parallel computing components and including performance tests
• Electronic and sensor design to develop uncooled multiaperture arrays in the MWIR and LWIR ranges
• Development of software modules for synchronized multi sensor acquisition

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

The major progress beyond the state of the art achieved during this period has to do with the positive results from initial tests on super resolution of infrared images, as well as on simultaneous spectral and super resolution reconstruction with visible images.
Besides, significant advances have been made towards the development of MWIR and LWIR multi aperture modules based on uncooled low cost FPAs.
