The invention provides a multi-angle scanning method, terminal equipment and a computer readable storage medium and relates to the field of one-dimensional code scanning technology. The method comprises the steps that a scanning angle of scanning a to-be-scanned image is acquired; the scanning angle is uploaded to an upper computer, and the upper computer calls an appropriate oblique position coordinate system, wherein the appropriate oblique position coordinate system is an oblique position coordinate system, corresponding to an oblique angle which has a minimum difference value with the scanning angle and is saved, in an oblique position coordinate system set; the appropriate oblique position coordinate system transmitted back by the upper computer is received; and picture feature data of the to-be-scanned image is acquired through coordinate values of pixels of the to-be-scanned image in the appropriate oblique position coordinate system. According to the method, by directly corresponding coordinates of the one-dimensional code image with an oblique angle to angle coordinate values in the oblique position coordinate system corresponding to the oblique angle, the picture feature data of the to-be-scanned image is acquired, and therefore the identification speed of one-dimensional code features is increased.
