The invention provides a lifting device space positioning device adopting monocular vision and a method. When each lifting device of a bridge crane moves, a spherical marker corresponding to the lifting device is driven to swing with a positioning hole as a fixing point; a monocular vision camera is used for photographing images obtained when the spherical markers swing to the position where included angles are generated between the spherical markers and the vertical direction from the part under an optical center; a signal processing device is used for processing the photographed images, some parameters such as coordinates of circle centers of circles, corresponding to the spherical markers, on the image plane where the optical center distance is equal to the focal length, and sphere center space coordinates of the spherical markers in a world coordinate system are obtained according to the calculation of the corresponding parameters. According to the lifting device space positioning device adopting monocular vision and the method, the sphere center space coordinates of the double lifting devices can be calculated, space positioning of the double lifting devices is achieved, the reference can be provided for a bridge crane driver, or finishing of synchronous or anti-swing control over the double-lifting double lifting devices is facilitated. The structure is simple, manufacturing cost is low, precision is high, and multiple signals can be measured at the same time.
