The invention discloses a spherical tank inner wall climbing trolley walking control method based on weld joint data, which is applied to the cross technical field of visual inspection, signal processing and motion control, and comprises the following steps: acquiring weld joint data, and preprocessing to obtain stable weld joint form data; performing straight line fitting on the weld form data by applying a Ransac algorithm to obtain an outlier set, determining a candidate weld area, performing parabola fitting in the candidate weld area, and identifying the weld position; the welding seam position serves as input of a PID control algorithm, and the advancing direction and the movement speed of the trolley are controlled. According to the invention, effective and stable identification and tracking movement can be carried out on various welding seam forms in various types of spherical tank inner walls, the automatic inspection requirement of the spherical tank inner walls in an unmanned ...
