Visualization Method of Bucket Terminal Yard Working Data

The 3D visualization technology is a kind of means and methods to achieve the human-computer interaction. Instead of the discrete objects in container terminal yard, the cargo in bulk terminal yard is always being a form with particle. This paper gives a method which integrates modeling manually and real-time reconstruction automatically to achieve 3D visualization of bulk terminal yard. Since to meet the requirement of real-time rendering and also decision data computing fast, this paper designs the data structure to describe the digital stockpile formed with a hierarchy relationship between surfaces, sections and space points, and also considers the closest distance as the main condition for searching and updating an old section, to visualize the working process in bucket terminal yard.
