The present invention relates to a device for detecting vehicle and a control method thereof. The purpose of the present invention is to maintain the quality of surrounding images to be greater than a certain level through gain control of images even if sudden change of surrounding environments is generated when the surrounding images are utilized for the automatic driving control of the vehicle. The control method of the device according to the present invention enhances the brightness of an interesting area by obtaining front vehicle images, lowering the brightness of the interesting area as the gain of the interesting area is controlled to be reduced when the brightness of the interesting area in which a target tracking vehicle is positioned in the front vehicle images is brighter than the predetermined first brightness, and increasing the gain of the interesting area when the brightness of the interesting area in the front vehicle images is darker than the predetermined second brightness. [Reference numerals] (302) Obtain the front images of a vehicle;(304) Is there any vehicle to be tracked ?;(306) Brightness of Region of Interest ��bright;(308) Reduce gains;(310) Brightness of Region of Interest ��dim;(312) Increase gains;(314) Fix gains & search for those vehicles which were tracked during previous cycles;(316) Identify vehicles & perform a tracking algorithm;(AA) Start;(BB,EE,GG) No;(CC,DD,FF) Yes;(HH) End |
