The invention provides a vision displacement measurement system comprising a reference board, a laser device arranged on a far end basis and a movable acquisition device. Laser beams emitted by the laser device are arranged in the reference board. The movable acquisition device comprises an image acquisition lens, and a measurement basis frame, a coordinate direction mark point and an information code are arranged on the surface of the reference board. A calibration grid is distributed in the basis frame, the information code is a bar code or a two-dimensional code, and corresponding reference board specification data and ID recognition information are set in the information code; the laser device and the mobile acquisition device are connected with a server terminal through electric signals. The system has the advantages that the whole system is low in manufacturing cost, and a lot of cost is reduced; displacement changes of a detected object can be measured more accurately by measuring changes of relative displacement, and accuracy is high; meanwhile, compared with existing fixed measurement, multi-angle multi-direction photographing control can be achieved, and the measurement and use range is wider.
