The invention relates to a regional moving vehicle flow detection method based on a video image technology. The method comprises steps as follows: firstly, acquiring continuous moving vehicle color images, and performing matching calibration on the color images by the aid of linear Hough transformation; secondly, performing grey level transformation on the color images, and performing a subtraction operation and an intersection operation on grey level images respectively to acquire weak images; performing linear stretching, binaryzation and binary expansion transformation on the weak images to acquire enhanced and expanded moving vehicle images, wherein signals are small communicated regions; finally, defining a Euclidean distance, calculating Euclidean distances between geometric center points of the communicated regions respectively on the basis of the defined distance, determining the number of final regions, and numerically marking the final regions. With the adoption of the regional moving vehicle flow detection method based on the video image technology, the vehicle condition and the congestion condition of a current road region can be estimated quickly, efficiently and simply, and the method can be well applied to practice.
