The invention relates to a machine-vision-based parking vehicle speed detection system. The system comprises a machine vision collection block, an image processing module, a vehicle speed sensor, a master control module and an execution module. The machine vision collection module is utilized for collecting real-time image sequences of a road surface in the parking process, the collected image sequences are processed through the image processing module, the real-time vehicle speed and parking environment characteristic information are worked out according to the processed image sequences, the master control module compares and analyzes the real-time parking vehicle speed calculated through the image processing module and the vehicle speed measured by the vehicle speed sensor for calculating the slip rate, and meanwhile feedback control is carried out on the machine vision collection module. The execution module accurately controls the steering wheel rotating angle parking speed according to the vehicle speed and the slip rate. The machine-vision-based parking vehicle speed detection system is low in cost, accurate in steering, high in reliability and capable of being used in the severe parking environment, the automatic vehicle parking varieties are increased, and the parking energy consumption is lowered.
