Design and Implementation of 3-D Measurement Method for Container Handling Target

In the process of automatic container terminal loading and unloading, three-dimensional attitude affects security unloading operations, so positioning is very important. this paper, a visual non-contact measurement method used to realize real-time orientation container. First, corner coarsely positioned by small-scale deep learning network. Secondly, precise position keyhole obtained secondary through traditional image processing algorithm, posture measured in three dimensions combining physical motion model during unloading. After testing, unlike previous methods, accuracy met requirements terminals, time measurement.
