Method for programming robot in vision base coordinate

A method for programming a robot in a vision base coordinate, comprising:

• drawing a robot to an operation point;
• selecting a coordinate system recorded at the operation point;
• setting the operation point as a new point, and setting coordinates and operation of the new point;
• checking whether the operation at the new point is a photo operation;
• capturing a teaching image at the new point and establishing a vision base coordinate system;
• and
• setting a follow-up point on the established vision base coordinate system;
• after the programming process is completed, the programming method further comprises:
• moving the robot to the operation point according to the selected coordinate system;
• checking whether the operation at the operation point is the photo operation;
• controlling the robot to capture an image, comparing the captured image with the teaching image and calculating a displacement of image and a difference amount in rotation angle according to the comparison result to search for an image being the same as the teaching image;
• checking whether the difference amount between the captured image and the teaching image is less than a predetermined value;
• checking whether the vision base coordinate system maintains the same corresponding relation as in the teaching process, so that the movement of the robot can be precisely controlled.
