Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] see figure 1 , a three-dimensional imaging method to realize real-time dynamic tracking of material piles. It uses the walking, pitching, and gyrating motions of the stacker-reclaimer to drive the laser scanning device installed in front of the stacker-reclaimer cantilever to dynamically scan the material piles. After preprocessing, coordinate conversion, grid normalization, and interpolation, the laser scanning data will be processed to generate regular 3D data, and finally a complete grid database of the entire stockyard will be generated.

[0031] The 3D imaging control reads out the grid coordinate information of the material yard from the database, takes the material yard as the image display area, and the material yard ground as the display base surface, and displays the corresponding z value for the x and y values ​​in the area, s...

Abstract

The invention relates to a stock pile identification method of a bulk-cargo stock ground. A three-dimensional imaging method for realizing the real-time dynamic tracing of a stock pile is disclosed, which drives a laser scanning device arranged at the front end of a cantilever of a material piling and taking machine to carry out a dynastic scanning to the stock pile by utilizing the running, pitching and circumnutation of the material piling and taking machine; a pretreatment, a coordinate transformation, a grid standardization processing and an interpolation are carried out to the obtained laser scanning data so as to generate regular three-dimensional data and to finally generate a complete grid data base of the whole stock ground; a three-dimensional imaging control component reads the coordinate information of the grid of the stock ground; the stock ground is taken as a display area of the image and the ground surface of the stock ground as a display base plane, thus realizing a coordinate restoration in the area and finishing the display of the three-dimensional images of the stock pile; and the content of the data in the data base is updated in a real-time manner: meanwhile, the change of the data content in the data base triggers the three-dimensional imaging control component to read the data from the data base, thus realizing the real-time dynamic updating of the three-dimensional stock-pile image displayed by a terminal.

Description

technical field [0001] The invention relates to a stockpile identification method in a bulk cargo stockyard, in particular to a three-dimensional imaging method for real-time dynamic tracking of a stockpile. Background technique [0002] Large-scale bulk cargo (such as ore, coal, small gravel, yellow sand, etc.) to realize unmanned stacking process, the primary task is to identify the stockpile in the stockyard, the key to identifying the stockpile is not only It is the size of the land, the height of the pile, and the shape of the pile that is constantly changing. Because the stockpile in the stockyard is dynamic during the operation, it is constantly increasing or decreasing. Existing recognition technologies generally use 3D holography, ultrasound, microwave, laser scanning, etc., but these technologies cannot realize real-time dynamic tracking, and the workload of data processing is heavy. Contents of the invention [0003] The object of the present invention is to p...
