Abstract

Disclosed is a double-lidar positioning method for hanger-container truck alignment belonging to container automatization field. The invention comprises firstly acquiring the type of the container truck during the container loading process or the container type during the container unloading process; then acquiring precise position or pose of the container truck lock during the container loading process or the container lockhole during the container unloading process; finally acquiring precise pose and position the hanger, computing the difference between the precise positions and poses of the container truck lock or the container lockhole and the hanger, real-timely adjusting the cylinder according to the hanger position and pose, thus to realize precise alignment positioning of the hanger and the container truck. The invention employs a block scan and error compensation method, and advanced software processing and hard control technologies to greatly improve the recognition precision and speed, make the system have redundance fault tolerance capability, and improve the loading and unloading efficiency.

Description

technical field [0001] The invention relates to a method in the technical field of container automation, in particular to a double laser radar positioning method for a spreader-collector to a container. Background technique [0002] The automation of container terminal production is the development trend of future port loading and unloading, and has been valued by major ports in the world. In the fully automated container terminals that have been built today, AGV (automatic unmanned automatic guided vehicle) is used to realize the horizontal transportation of containers in the terminal. In this way, when the AGV runs under the RMG, it can be convenient and accurate only through the positioning sensor. Realize the positioning of AGV. However, in the early stage of the construction of automated storage yards, due to the immaturity of financial resources and technology, generally only automatic loading and unloading technology will be used in the storage yards in some areas of...
