Wide dynamic range vision sensor for autonomous vehicles
Proceedings of 1995 IEEE International Conference on Robotics and Automation, 2002The dynamic range insufficiency of conventional video cameras is an important problem in realizing robust vision systems for autonomous vehicles. To solve the problem, a method for expanding the dynamic range of video cameras by combining the images taken under different exposure conditions has been developed.

Research on Brain-inspired Vision Based on Dynamic Vision Sensor Cameras
Proceedings of the 2020 International Conference on Aviation Safety and Information Technology, 2020In this paper, we explored many applications of brain-inspired vision, in which the data was acquired based on a dynamic vision sensor camera, that is PSEE300EVK from French. Specifically, we explored the following three aspects: (1) Converting large-scale artificial convolution neural network into spiking neural network, which can process large-scale ...

A Microbolometer Asynchronous Dynamic Vision Sensor for LWIR
IEEE Sensors Journal, 2009In this paper, a novel event-based dynamic IR vision sensor is presented. The device combines an uncooled microbolometer array with biology-inspired (ldquoneuromorphicrdquo) readout circuitry to implement an asynchronous, ldquospikingrdquo vision sensor for the 8-15 mum thermal infrared spectral range.

Wide dynamic range vision sensor for vehicles
Proceedings of VNIS'94 - 1994 Vehicle Navigation and Information Systems Conference, 2002The dynamic range of brightness on road scenes is very wide, because the lighting condition dynamically varies with various weather and road conditions. Therefore, the dynamic range of conventional TV cameras is insufficient to input the images of road scenes. The authors have developed a method for expanding the dynamic range of TV cameras. Also, they

Dynamic vision sensor for low power applications
The 18th IEEE International Symposium on Consumer Electronics (ISCE 2014), 2014This paper presents the design of a dynamic vision sensor for mobile applications. The sensor features a standby mode with less than 250uW of power dissipation. The sensor changes operation mode between standby and normal operation itself depending on input activity.

Observing auroras with dynamic vision sensors
Auroras are a faint space weather light phenomenon caused by the interaction between the solar wind and the Earth’s magnetic field. This interaction can lead to processes that increase the energy of charged particles in the magnetosphere, enabling the particles to enter the ionosphere and cause diffuse or discrete auroras.Andreas Stokholm +7 more

CARE: A dynamic stereo vision sensor system for fall detection
2012 IEEE International Symposium on Circuits and Systems, 2012This paper presents a recently developed dynamic stereo vision sensor system and its application for fall detection towards safety for elderly at home. The system consists of (1) two optical detector chips with 304×240 event-driven pixels which are only sensitive to relative light intensity changes, (2) an FPGA for interfacing the detectors, early data
