Device and method for detecting heights of material piles at material throwing positions of dock wall moving type ship loader

Provided are a device and method for detecting heights of material piles at material throwing positions of a dock wall moving type ship loader. A laser radar assembly is installed on a ship loader installing platform so as to be used for performing real-time scanning on the material throwing process and a material pile state of the current material throwing positions and then calculating the material pile heights. The device and method for detecting the heights of the material piles at the material throwing positions of the dock wall moving type ship loader are high in accuracy and good in stability, interference of various factors such as driver experience, moods and weather is removed, safety in the automatic blanking process is guaranteed well, and the ship loader can automatically finish bulk cargo shipping operation on the basis of safety in operation.
