The invention provides an optical label shooting and optical label decoding relay work method. An optical label comprises two parts, i.e., a signal unit group or a "data bit" for short and a positioning identification or a "flag bit" for short. Through converting the shooting frequency of shooting equipment and eliminating a motion displacement image of the equipment, an optical label and a background image are simultaneously acquired, and alignment and superposing synthesis of two kinds of shooting image content are realized. Data transmission of the optical label is guaranteed, the background image where the optical label is disposed is also reserved, onsite experience of a user in using the optical label is improved, and the method solves the problems which cannot be solved by other label ( such as two-dimensional codes and bar-codes) methods.
