Paper Abstract

On a container dock, the container truck must be parked right under the trolley of the container crane before loading (unloading) a container to (from) it. But it often uses nearly one minute to park the truck at the right position because of the difficulty of aiming the truck at the trolley. A monocular machine vision system is designed to locate the locomotive container truck, give the information about how long the truck need to go ahead or go back, and thereby help the driver park the truck fleetly and correctly. With this system time is saved and the efficiency of loading and unloading is increased. The mathematical model of this system is presented in detail. Then the calibration method is described. At last the experiment result testifies the validity and precision of this locating system. The prominent characteristic of this system is simple, easy to be implemented, low cost, and effective. Furthermore, this research work verifies that a monocular vision system can detect 3D size on condition that the length and width of a container are known, which greatly extends the function and application of a monocular vision system.
