Method for detecting lane line, vehicle and computing device

A method for detecting a lane line to be executed by a computing device, comprising:

• generating an optical flow image in accordance with a series of event data from a dynamic vision sensor coupled to a vehicle, each event being triggered by movement of an object in a scenario relative to the dynamic vision sensor;
• determining an initial search region comprising a start point of the lane line in accordance with the optical flow image;
• determining a center of gravity of the initial search region;
• determining a new search region through an offsetting operation on the center of gravity;
• determining a center of gravity of the new search region;
• repeating the steps of determining a new search region and determining a center of gravity of the new search region iteratively to acquire centers of gravity of a plurality of search regions;
• and
• determining the lane line in accordance with the centers of gravity of the plurality of search regions.
