The invention discloses a wheel-rail adhesion coefficient determination method and system based on image recognition, and the method employs a CCD industrial camera to achieve the non-contact measurement of the wheel-rail operation speed, and employs an image processing technology to process the wheel-rail image information in real time to obtain the wheel-rail operation speed, thereby obtaining the wheel-rail creep rate. According to the wheel rail adhesion creep characteristic curve in the storage database, the adhesion coefficients of all the wheels and the steel rail contact area when the train runs at the current speed are obtained, the adhesion coefficient of any wheel set is obtained, and non-contact real-time measurement of the adhesion coefficients of the wheel sets is achieved; and data support is provided for improving an anti-slip or anti-slip control method and strategy for train operation.
