OVERTAKING VEHICLE WARNING SYSTEM AND OVERTAKING VEHICLE WARNING METHOD?‹

摘要

The present invention provides an overtaking vehicle warning system comprising: an image filming unit attached to the front of a vehicle and filming the front of the vehicle; a driving unit setting an interesting area by receiving image data from the image filming unit, extracting characteristics of vertical edges from the interesting area, and generating a warning signal if characteristics matched by comparing with characteristics of a previous frame is greater than a threshold value; and a warning unit receiving the warning signal and generating an overtaking vehicle warning signal. Accordingly, the characteristics are searched by searching edge areas from the image filming the front and a vehicle having corresponding characteristics is traced so that the warning relative to an overtaking vehicle can be generated.;COPYRIGHT KIPO 2014;[Reference numerals] (S100) Image frame reception;(S200) Image preprocessing;(S300) Characteristic tracking through distance conversion;(S400) Characteristic counting based on the direction of the traffic;(S500) Countm+h;(S600) Postprocessing;(S700) No passing spotted;(S800) Passing warning generation
