A sun sensor implemented with an asynchronous luminance vision sensor
ESSCIRC 2017 - 43rd IEEE European Solid State Circuits Conference, 2017 A sun sensor implemented with a spiking pixel matrix is reported. It is the very first one based on an asynchronous event-based pixel array. A paradigm associated to classic digital sun sensors is solved with this approach. Only pixels illuminated by the sun light are readout. Hence, the output data flow is quite reduced.

Modeling and Calibration of Inertial and Vision Sensors [PDF]
The International Journal of Robotics Research, 2010 This paper is concerned with the problem of estimating the relative translation and orientation of an inertial measurement unit and a camera, which are rigidly connected. The key is to realize that this problem is in fact an instance of a standard problem within the area of system identification, referred to as a gray-box problem.
