Abstract
The invention discloses a television monitoring system for tracking a set vehicle. A plurality of video detection units that are arranged at a road with a certain distance from an intersection are utilized to detect license number information of a driving vehicle; a data processing unit compares the license number information of the driving vehicle with stored license number information of a set vehicle; when the license number information is matched, a comparison and determination module issues a presetting instruction that is set in advance to a camera, and thus the camera is controlled to be pointed to the vehicle immediately and an instruction is issued to a prompting unit simultaneously, so that the prompting unit sends out voice prompt; and a commander immediately controls the camera to make movements according to the voice prompt and thus the vehicle that the current camera is pointed to is always displayed on a display terminal. Meanwhile, the invention also discloses a monitoring method that applies the monitoring system to monitor a set vehicle. According to the invention, a problem that television monitoring can not enable a set vehicle to be displayed in real time in the prior art can be solved. The monitoring system and the monitoring method are widely applied to a special vehicle monitoring system of urban traffic.
