The invention discloses a strip steel deviation detection method based on a binocular vision monitoring system. The strip steel deviation detection method comprises the steps that 1, a binocular camera is centrally erected above a strip steel advancing path and is connected with an image processing part; 2, the strip steel advances, and the binocular camera collects image data in real time and sends parallax image data to an image processing part in a parallax output mode; 3, extracting a parallax value of each pixel from the parallax image data by the image processing part, and recalibrating the parallax value through RGB (Red, Green, Blue) colors to generate a sideline enhanced parallax image; 4, identifying the edge of the strip steel, and generating a strip steel parallax binary image; and 5, determining the edge position of the strip steel according to the strip steel parallax binary image, calculating the center line of the strip steel, and judging whether the strip steel deviates or not and the severit
