Abstract: In the new generation of artificial intelligence, neuromorphic vision is an important research direction of neuromorphic computing. Event camera has the advantages of low power consumption, low information redundancy and high dynamic range, and it has important application value in autonomous control scenes of intelligent aircraft and agile robots. Based on the spatio-temporal characteristic of event sequence, this paper studies the principle of optical flow estimation based on local plane fitting, proposes an algorithm that uses eigenvalue method to perform local plane fitting to estimate optical flow, and uses RANSAC method to further improve the robustness of this algorithm. Experiments show that the method proposed in this paper can effectively estimate the optical flow for neuromorphic vision and is robust to noise.

Key words: neuromorphic vision, optical flow estimate, local plane fitting
