ICNS researchers outline calibration for neuromorphic event-based cameras for space imaging

Six researchers from the International Centre for Neuromorphic have collaborated on a paper recently published in the peer-reviewed international journal, Astrodynamics. The paper presents the techniques and systems used for calibrating an event-based camera (EBC) for reliable and accurate measurement acquisition. These techniques are vital in building event-based space imaging systems capable of real-world space situational awareness tasks.

The nature of event-based space imaging and data collection needs to be further explored to develop more effective event-based space imaging systems and advance the capabilities of event-based tracking systems with improved target measurement models. Moreover, for event measurements to be meaningful, a framework must be investigated for EBC calibration to project events from pixel array coordinates in the image plane to coordinates in a target resident space object’s reference frame. In this paper, the traditional techniques of conventional astronomy are reconsidered to properly utilise the EBC for space imaging and space situational awareness.

Dr Nicholas Ralph conducted the investigation, developed the methodology and software, performed the validation, and wrote the original draft. Dr Alexandre Marcireau collected the data used in this study and reviewed the final manuscript. Dr Saeed Afshar, Dr Nicholas Tothill, Professor André van Schaik and Associate Professor Gregory Cohen

reviewed and edited the original draft, supervised the project, and contributed to the methodology.
