The revolution mechanism is one of the very important elements of machine tool. So, we studyed the measuring methods of the main spindle revolution by image processing technique which is in the improvement stage for practical apprication in many field recently. To calculate the rotation angle, we showed four algorithms and considered those caluculation accuracy and time theoretically and experimentally. According to the computer simulations and experimental results on lath, one of those algorithms can caluculate the rotation ange with accuracry comparing with others and another caluculation time is more shorter. Therefore, if the appropriate method is selected according to need in computer programing, machine tool spindle revolution can be measuered practically by the image processing techniques instead of rotary encoda which is used widely, but has to be fixed in machine tool.
