Problems solved by technology

The key technology of the existing laser scanning positioning system is mastered by foreign manufacturers, and the price is very expensive. Many large-scale mechanical laser scanning technologies need to install multiple devices to realize the function, and the cost doubles.
For example, the cranemate-based laser sensor positioning system will greatly increase the cost due to the limitation of the installation location

Abstract

The invention discloses an automatic container lockhole identifying-positioning method and system. A camera collects an image, a container lockhole in the image is positioned, a device coordinate system is obtained and then transmitted to a controller for subsequent control processing, a controller positions the device according to a given position, and a container is grabbed if the position is effective and safe. The method and system can improve the positioning precision, reduce the positioning cost and can expand functions according to requirements.

Description

technical field [0001] The invention relates to a technology for identifying and locating a lock hole of a container, in particular to a method and a system for automatically identifying and locating a container lock hole by using an industrial camera. Background technique [0002] In the process of grabbing the container, it is necessary to locate the keyhole of the container. The current positioning adopts the technology of laser scanning positioning. The key technologies of existing laser scanning positioning systems are all mastered by foreign manufacturers, and the price is very expensive. Many large-scale mechanical laser scanning technologies need to install multiple devices to realize their functions, and the cost doubles. For example, the cranemate-based laser sensor positioning system will greatly increase the cost due to the limitation of the installation location. [0003] Therefore, the industry urgently needs to reduce the positioning cost of the container key...
