The invention relates to a system for automatically associating, processing and controlling a portrait of a vehicle running the red light. The system comprises a camera module, a main control module, a storage module and a power supply module. The invention further relates to a method for automatically associating, processing and controlling the portrait of the vehicle running the red light on the basis of the system. By adopting the system and the method for automatically associating, processing and controlling the portrait of the vehicle running the red light, a red light running image can be automatically associated with a bayonet portrait image, complete red light running data can be acquired, the data can be also locally stored or are transmitted to a remote control center for analysis and processing in real time in optical fiber, ADSL and wireless transmission modes (GPRS/SMS), the illegal phenomena in traffic can be powerfully stuck, the phenomena of 'substitutive score penalty' and 'substitutive penalty' in the society can be eliminated, the running security of a road intersection can be ensured, and the system is simple and practical in structure, rapid and convenient in processing, stable and reliable in working property and relatively wide in application range.
