This paper proposes a vision system for vehicle velocity estimation based on asynchronous output data. For real-time velocity estimation, a processing method has been developed and implemented on a digital signal processor. It exploits the sparse asynchronous data representation from the dual-line sensor with high temporal resolution (better than 100 mus) and low latency. The processing concept includes...
The architecture and prototype applications of an embedded vision system containing a neuromorphic temporal contrast vision sensor and a DSP are presented. The asynchronous vision sensor completely suppresses image data redundancy and encodes visual information in sparse address-event-representation (AER) data. Due to the efficient data preprocessing on the focal plane, the sensor delivers high temporal...
