The invention relates to a vehicle body paint surface defect video detection method and system, and the method achieves the precise positioning of a vehicle body through the comparison of vehicle body marks and the feedback correction of the position of the vehicle body according to a comparison result, and eliminates the position error when the vehicle body enters a detection station. And the light source RGB is adjusted according to the vehicle type information, the color of the light source is automatically adjusted according to different vehicle color settings, the influence of the color on imaging is eliminated, the definition of the vehicle body paint image is effectively improved, and the defect detection process is more efficient. Besides, the vehicle body image is detected through the defect detection model, and the defect detection model carries out training convergence on various vehicle body paint surface defects in advance, so that rapid detection of the paint surface defects is realized, the req
