Image acquisition method of tower drum flange flatness detection equipment

The invention discloses an image acquisition method of tower flange flatness detection equipment, which comprises a vertical centering stage and an image acquisition stage, and the vertical centering stage and the image acquisition stage are both completed through a detection system. Compared with the prior art, the image acquisition method of the tower flange flatness detection equipment comprises the vertical centering stage and the image acquisition stage, the detection system automatically aligns the axis of the rotating arm with the circle center of the flange through the automatic centering stage so as to achieve the optimal visual field and the working distance of the 3D industrial camera, and in the image acquisition stage, the rotating arm drives the 3D industrial camera to rotate, full-coverage type laser line scanning is carried out on the target flange to obtain mass point cloud data, and the point cloud data of a laser line scanning area can be obtained by rotating for a circle. 本发明公开了一种塔筒法兰平面度检测
