The wide-adaptability bar code provided by the embodiment of the invention takes the change of the color of the bar code as a coding rule, and when the bar code is attached to the surface of an object and is raised and distorted, the bar code can still be quickly and correctly identified by a bar code identifier. The defects that the traditional bar code can be identified only by keeping flat, and cannot be used for soft, uneven surface or curved surface objects are overcome.
On the basis of the above embodiment, the th color is black, the second color is white, and the third color is gray.
