Improved YOLOv5 network for high-precision three-dimensional positioning and at...
Zhang, Y.; Song, Y.; Zheng, L.; Postolache, O.; Mi, C.; Shen, Y.For automated quayside container cranes, accurate measurement of the three-dimensional positioning and attitude of the container spreader is crucial for the safe and efficient transfer of containers. This paper proposes a high-precision measurement method for the spreader’s three-dimensional position and rotational angles based on a single vertically mounted fixed-focus visual camera. Firstly, an image preproce...
Design and implementation of 3-D measurement method for container handling target
Mi, C.; Huang, S.; Zhang, Y.; Zhang, Z.; Postolache, O.In the process of automatic container terminal loading and unloading, the threedimensional attitude of the container affects the security of loading and unloading operations, so the three-dimensional attitude positioning of the container is very important. In this paper, a visual non-contact measurement method is used to realize the real-time orientation of the threedimensional attitude of the container. First,...
