Small cone taper detection error analysis method and device, terminal and medium

The invention discloses a small cone taper detection error analysis method and device, a terminal and a medium, and belongs to the technical field of taper detection.The small cone taper detection error analysis method comprises the steps that when an error analysis request is received, small cone related data and a cone taper detection error value in the error analysis request are obtained respectively; and obtaining a small cone taper detection compensation value through the small cone related data and the cone taper detection error value. According to the small cone taper detection error analysis method and device, the terminal and the medium, the geometric property of the cone is combined, the error reason of oil pipe joint taper detection of the roughness contourgraph is determined, the method for reducing the measurement error is formulated according to the actual situation, the accuracy of taper measurement can be effectively improved, and the measurement efficiency is improved. Meanwhile, the measurin
