High-speed vision measurement device and method for analyzing motion posture of thin cylinder

The invention discloses a high-speed vision measurement device and method for analyzing the motion posture of a thin cylinder, and the method mainly comprises the steps: shooting a target thin cylinder through a high-speed camera, obtaining image information, and determining a first parameter and a second parameter of the camera based on the analysis and calculation of the image information; determining corrected images M1 and M2 based on the first parameter and the second parameter in combination with the distortion coefficient; determining segmented images R1 and R2 based on an image segmentation technology, and determining centroid coordinates (U1, V1) and (U2, V2) of a target thin cylinder in the segmented images R1 and R2 based on a first-order center distance; global coordinate system conversion is carried out on the centroid coordinates (U1, V1) and (U2, V2) through a preset conversion relation to determine world coordinates (Xw, Yw, Zw) of the centroid of the target thin cylinder; constructing a thin
