The invention relates to the field of assembly line work and provides a visual positioning method for assembly line work. The method includes that a CCD (charge coupled device) visual positioner positions a workpiece on a first station; a processor controls calibration of manipulators on follow-up stations or adjustment of the position of the workpiece according to positional information of the workpiece on the first station; working of the manipulators and moving of the workpiece are controlled. The invention further provides a visual positioning device and a visual positioning system for the assembly line work. A multi-station assembly line in the method, device and system is only provided with one CCD visual positioner, movement or operation of the manipulators on the assembly line is calibrated according to the positional information of the workpiece positioned by the CCD visual positioner, or the workpiece on the station is adjusted, and accordingly the whole assembly line can be positioned by only one C
