Container contour scanning system and method

The invention discloses a container contour scanning system and method, and relates to the technical field of container hoisting. The container contour scanning system comprises a support frame, a first sliding rail, a second sliding rail, a hoisting device and a laser scanning device, wherein the support frame is provided with a cross beam and a support column; the first sliding rail and the second sliding rail are arranged on the cross beam; the hoisting device is arranged on the first sliding rail in a sliding mode and is used for lifting and carrying a container; and the laser scanning device is slidably arranged on the second sliding rail. Therefore, the laser scanning device is arranged on the cross beam of field bridge equipment, the laser scanning device can be started in advance for rapid scanning when the support frame is not completely in place and the hoisting device does not move, a real-time and complete bay container contour diagram is provided, the problem of a scanningblind area is solved, th
