For an axial bar code rectangular image with a straight line inclined, after obtaining a straight line inclination equation of an axial boundary point by using the calculation method, we can consider that depending on the axial inclination of the boundary line, a bar code axis can be pushed and translated to a certain level by rapidly rotating the bar code image.Normally, the method of rotation axial spiral is used to correct the axial inclination of the image angle on the bar code<br>
