AI Technical Summary

Technical Problem

In port terminal operations, the container loading process relies on manual control, resulting in low operational efficiency, insufficient precision, and high labor costs.

Method used

By acquiring visual information of the container being mounted on the spreader, the outline information of the container is determined by fitting a curve using discrete points. The spreader is then controlled based on the outline information and visual information, including fitting using the least squares method and batch gradient descent algorithm, and deviation evaluation and adjustment by combining an artificial intelligence model.

Benefits of technology

It improved the efficiency and accuracy of container placement with the spreader, reduced labor costs, and enabled automated control of the spreader.
