Binocular vision-based synchronous operation lifting system detection system and method

The invention relates to a binocular vision-based synchronous operation lifting system detection system and a method. The system comprises a synchronous operation lifting system, two CCD (Charge Coupled Device) cameras, bases of the CCD cameras, a plurality of artificial target points, two auxiliary light sources and a computer, the two CCD cameras are mounted over the synchronous operation lifting system, the artificial target points are respectively mounted at different positions on the synchronous operation lifting system, and the two CCD cameras can continuously acquire and transmit the images of the artificial target points to the computer. The method includes the following steps: a coordinate system is established, the two cameras respectively acquire and transmit a digital image of the artificial target points to the computer, the image information of the two cameras are integrated, the binocular vision imaging theory is utilized to calculate the three-dimensional coordinates of each artificial target point under the world coordinate system, and linear operation is then utilized to work out the synchronism and verticality error of each lifting axis of the synchronous operation lifting system. The non-contact, disturbance-less and high-frequency measurement of the synchronous operation lifting system is realized.
