With the applied computer vision technology, the boot of automobile shaft is measured real-timely under a high rotation speed and high temperature condition, and an extraction method of pixel-level object profile curve is introduced. Besides, the radial dilation of the boot is obtained accurately through averaging several measurement results on a basis of pixel-level edge. During the test course, the boot not only dilates in radial direction but also deforms in axial direction. According to the characteristic of the measurement object variation, this paper presents a modification algorithm, which processes departure in segments along the X coordinate, to reduce the measurement deviation from deformation in axial direction, and the measurement accuracy of the boot profile dimension is improved.
