Problems solved by technology

[0004] The existing stacker-reclaimer operation mode is mostly manual operation. The operator sits in the cab to operate the stacker-reclaimer, which requires a high degree of concentration, and the job site is dusty, the working environment is relatively harsh, and the labor intensity of the operators is relatively high. Big
Moreover, when working, the line of sight is often blocked, and potential safety hazards are likely to occur during the operation

Embodiment 1

[0048] Embodiment 1 of the present invention provides an automatic reclaiming system based on raw material field scanning and imaging, and the automatic reclaiming system includes:

[0049] The image acquisition device is arranged on both sides of the boom of the reclaimer, and is used for collecting and acquiring the point cloud image data of the material pile, and extracting the three-dimensional point cloud model of the material pile in the point cloud image data of the material pile;

[0050] The stack height calculation module is used to obtain the stack height through point cloud merging, denoising, segmentation and fitting of the 3D point cloud model of the stack;

[0051] The layering module is used to layer the stack height according to the preset reclaiming process strategy;

[0052] The control parameter calculation module is used to calculate the operation control parameters of the reclaimer according to the layered 3D point cloud model;

[0053] The controller is...

Embodiment 2

[0074] like figure 1 As shown, this embodiment 2 provides an automatic material reclaiming method based on scanning and imaging of a raw material field. The premise of realization is to obtain a model of the material pile. Before the operation, a scanning imaging device is used to obtain a point cloud image of the material pile. After obtaining the point cloud image data of the material pile, it is necessary to first determine whether the material pile is a new pile. If it is a new pile, it is necessary to calculate the control parameters of the stacker and reclaimer according to the point cloud image data of the material pile. Secondary operation records, no need to recalculate stacker-reclaimer control parameters, improve efficiency. After extracting the point cloud data model of the discharge pile, the pile height can be obtained through point cloud merging, denoising, segmentation and fitting processing. According to the existing reclaiming process parameters, the pile hei...

Abstract

The invention provides an automatic material reclaiming method and system based on scanning and imaging of a raw material field, belonging to the technical field of mechanical automatic material reclaiming. Model; the three-dimensional point cloud model of the material pile is merged, de-noised, segmented and fitted to obtain the height of the material pile; according to the preset reclaiming process strategy, the height of the material pile is stratified; The three-dimensional point cloud model calculates the operation control parameters of the reclaimer; according to the operation control parameters, the movement of the reclaimer is controlled to realize automatic reclaiming. The invention processes the images of the material pile acquired in real time, determines the operation motion parameters of the reclaimer according to the process requirements, and controls the reclaimer according to the operation motion parameters to realize the automatic reclaiming of the material pile, without manual on-site operation, reducing the It reduces labor intensity, improves work efficiency, reduces labor cost, and improves production safety.

Description

technical field [0001] The invention relates to the technical field of mechanical automatic material reclaiming, in particular to an automatic material reclaiming method and system based on raw material field scanning imaging. Background technique [0002] In steel production, the raw material yard is used to store, transfer and transport raw materials, which is the guarantee of steel production. The raw material yard mainly stores the raw materials and fuels required in the steel refining process. The raw material and the area where the raw materials are stacked are called stockpiles, and the feeding process is the process of transporting the raw materials on the designated stockpiles to the blast furnace and other smelting devices. [0003] During the feeding process, the raw materials on the pile need to be reclaimed on the conveyor belt through the stacker-reclaimer, and the conveyor belt will be transferred to the blast furnace and other smelting devices. [0004] The...
