The invention provides a
missile carrier positioning ring assembling method and
system based on vision and angle registration, and the method comprises the steps: collecting a
missile carrier positioning hole region image through an industrial camera, extracting hole position geometric information after
image processing, and calculating the angle of a
missile carrier positioning hole column relative to a camera coordinate
system; the chuck is controlled by the PLC to rotate the missile carrier, and the target hole column of the missile carrier is adjusted to be in the vertical upward direction; acquiring an image of the positioning ring, identifying asymmetric structure features to extract a main shaft
direction angle, and calculating an angle difference between the missile carrier and the positioning ring; a positioning ring is clamped through a clamp at the
tail end of a
robot, a planning path is converted through a multi-stage coordinate
system, angle pre-compensation is conducted on the positioning ring in the carrying process, the positioning ring is inserted into a missile carrier hole site through an adsorption and limiting structure, and meanwhile the
insertion force and speed are adjusted based on feedback of a force /
torque sensor; and after
assembly, collecting a reinspection image, analyzing and evaluating the
insertion depth and the boundary offset through
edge matching, and judging whether the
assembly is qualified or not according to a preset threshold value.
