It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] The present invention provides a method, device, electronic equipment and storage medium for measuring ore output of a scraper, which are described below respectively.

[0024] Figure 1 A schematic diagram of a flow chart of an embodiment of a method for measuring the ore output of a shovel loader provided by the present invention is shown in FIG. Figure 1 As shown in the figure, the ore-discharging metering method for scraper loader includes: S101, obtaining three-dimensional scanning data of the ore pile; S102, generating three-dimensional point cloud data according to the three-dimensional scanning data, performing denoising preprocessing on the three-dimensional point cloud data to obtain denoised point cloud data, performing point cloud volume calculation on the denoised point cloud data to obtain ore pile volume data, determining a volume change of the ore pile according to the ore pile volume data, and determining the ore output of the shovel loader according to the volume change of the ore pile and preset ore density data.

[0025] Specifically, the method for measuring the output of a shovel loader provided by the present invention first obtains three-dimensional scanning data of the ore pile; then generates three-dimensional point cloud data based on the three-dimensional scanning data, performs denoising preprocessing on the three-dimensional point cloud data to obtain denoised point cloud data, performs point cloud volume calculation on the denoised point cloud data to obtain ore pile volume data, determines the volume change of the ore pile based on the ore pile volume data, and determines the output of the shovel loader based on the volume change of the ore pile and preset ore density data. The present invention calculates the output of the shovel loader by calculating the volume change of the ore pile through three-dimensional scanning and point cloud volume calculation, which can effectively avoid the influence of environmental factors and driver operation on the output measurement, improve the accuracy of measurement, and obtain effective measurement data.

[0026] In some embodiments of the present invention, obtaining three-dimensional scanning data of a ore pile includes: The ore pile is 3D scanned before and after the loader leaves the mine to obtain 3D scanning data.

[0027] Specifically, in order to avoid the influence of the environment and the driver's operation on the measurement accuracy, the embodiment determines the volume change of the ore pile before and after the shovel loader leaves the mine by scanning, so as to determine the ore output of the shovel loader.

[0028] In the process of scanning the ore pile, the embodiment first emits laser pulses to the ore pile through the laser in the laser radar device. These laser pulses have specific wavelengths and energy. When the laser pulses are irradiated to the target object, part of the light will be reflected. The receiver in the laser radar device receives the reflected light and converts the optical signal into an electrical signal to obtain three-dimensional scanning data.

[0029] In some embodiments of the present invention, generating three-dimensional point cloud data according to three-dimensional scanning data includes: The coordinate data of each scanning reflection point is determined according to the three-dimensional scanning data, and the three-dimensional point cloud data is generated according to the coordinate data of each scanning reflection point.

[0030] Specifically, after receiving the 3D scanning data, the embodiment determines the distance between the target object and the laser radar according to the time difference between the laser pulse emission and the received reflected light in the 3D scanning data, and the distance can be calculated according to the time difference and the speed of light. At the same time, the laser radar can measure target objects at different angles by changing the emission direction of the laser, and measure and record the angle of laser emission and the angle of received reflected light.

[0031] The embodiment then processes the measured distance and angle information, and combines the position and attitude information of the laser radar to determine the three-dimensional coordinates of each reflection point on the target object. Then, as the laser radar continuously emits pulses and receives reflected light, more and more points on the target object are measured, and three-dimensional point cloud data is generated based on the three-dimensional coordinates of each reflection point.

[0032] In some embodiments of the present invention, performing denoising preprocessing on three-dimensional point cloud data to obtain denoised point cloud data includes: The three-dimensional point cloud data is subjected to noise point filtering and data filtering in turn to obtain denoised point cloud data.

[0033] Specifically, in the denoising preprocessing, due to various interference factors in the environment, such as dust, water vapor, and electromagnetic interference, there will be some noise points in the collected point cloud data, and the noise points need to be filtered out first. In the noise point filtering, the embodiment calculates the average distance between each point in the point cloud and several adjacent points. If the average distance exceeds a preset distance threshold, the point is considered to be an isolated noise point and is removed.

[0034] In addition, in order to make the point cloud data smoother and more accurate, data filtering is also required. Data filtering can remove high-frequency noise and retain useful low-frequency information. In the embodiment, various methods such as Gaussian filtering and median filtering can be used for data filtering. Gaussian filtering makes the point cloud data smoother by weighted averaging each point and the points around it. Median filtering replaces the value of each point with the median of the points within a certain range around it, which can effectively remove noise.

[0035] In some embodiments of the present invention, Figure 2 FIG. 1 is a flow chart of point cloud volume calculation according to an embodiment of the present invention. Figure 2 As shown in the figure, the denoised point cloud data is subjected to point cloud volume calculation to obtain the ore pile volume data, including: S201, performing coordinate transformation, geometric feature extraction and target object segmentation on the denoised point cloud data in sequence to obtain point cloud geometric data; S202, performing volume calculation on the point cloud geometric data based on a convex hull algorithm to obtain ore pile volume data.

[0036] Specifically, in the process of completing denoising and calculating the point cloud volume, since the denoised point cloud data at this time is data in the laser radar's own coordinate system, in order to integrate these point cloud data with other devices and maps, they need to be converted to a unified world coordinate system. The embodiment obtains the position and posture of the laser radar at this time through the sensor, and converts the denoised point cloud data from the laser radar coordinate system to the world coordinate system according to the coordinate conversion formula.

[0037] It should be noted that the above is only a data collection method of one embodiment of the present invention. In other embodiments, according to actual application requirements, other sensors may be used, such as cameras or GPS, or laser radars set on other devices. The data collected by other sensors also need to be converted to the world coordinate system so that data from different sources can be analyzed in the same coordinate system.

[0038] Then the embodiment needs to extract geometric features from the point cloud data, including plane extraction and edge extraction. Plane extraction takes into account that in an underground mine environment, there may be many plane structures, such as the walls and ground of the tunnel, so these planes can be identified through plane extraction. In the embodiment, the plane extraction algorithm adopts RANSAC (RANdom SAmpleConsensus, random sampling consistency algorithm), which assumes a plane by randomly selecting some points, and then calculates the distance from other points to this plane, and continuously iterates and optimizes until the best plane model is found. Edge extraction is to extract and identify the boundaries of objects, which is very important for identifying the shape and position of objects. The embodiment extracts edge points from point cloud data through an edge detection algorithm. The edge detection algorithm calculates the normal vector of each point, and then determines whether it is an edge point based on the change of the normal vector. Points with large changes in the normal vector are usually located at the edge of the object.

[0039] Then, according to the result of feature extraction, the embodiment uses a clustering algorithm to classify points with close distances into the same category, so that target objects with different point cloud data can be separated. For example, ore piles and pillars in the tunnel can be separated from the surrounding walls and ground.

[0040] For the segmented target objects, the geometric size and volume are automatically calculated according to the built-in algorithm. For relatively shaped objects, such as a pile of ore stacked into a cuboid, the volume calculation formula is used for calculation. For irregularly shaped objects, the embodiment uses a convex hull algorithm to calculate the point cloud data. In the convex hull algorithm, the convex hull refers to the smallest convex polygon containing all points. The approximate size of the target object can be obtained by calculating the size of the convex hull. The Graham scanning method is used to calculate the convex hull in the embodiment.

[0041] In some embodiments of the present invention, the ore pile volume data includes the ore pile volume data before mining and the ore pile volume data after mining. Figure 3 FIG. 1 is a flow chart of calculating the ore output of a shovel loader according to an embodiment of the present invention. Figure 3 As shown, the volume change of the ore pile is determined according to the ore pile volume data, and the ore output of the loader is determined according to the ore pile volume change and the preset ore density data, including: S301, determining a volume change of the ore pile according to the volume data of the ore pile before and after the ore pile is unearthed; S302, determining the ore output of the shovel loader according to the volume change of the ore pile and the preset ore density data.

[0042] Specifically, the embodiment obtains the volume of the ore pile before and after shoveling out of the mine through three-dimensional scanning and point cloud volume calculation, and can subtract the volume change of the ore pile before and after the operation, and then the volume change is combined with the preset ore density data obtained by pre-sampling and testing the ore pile to determine the weight of the ore discharged by the shovel loader. , the formula is:

[0043] in, To preset the ore density, is the volume of the ore pile after mining, It is the volume of the ore pile before mining.

[0044] In some embodiments of the present invention, the method for measuring the ore output of a scraper further includes: Generate ore output analysis statistics based on the ore output of the loader, and build a shovel operation strategy based on the ore output analysis statistics; Among them, mining analysis statistics include total statistics, average mining statistics, fluctuation analysis, comparative analysis and correlation analysis.

[0045] Specifically, in order to improve the efficiency of shoveling operations, the shovel loader ore output measurement method in the embodiment also analyzes and counts the shovel loader ore output, including total output statistics, average output statistics, fluctuation analysis, comparative analysis and correlation analysis, and constructs a shoveling operation strategy based on the results of the statistical analysis.

[0046] The total amount statistics is to calculate the total ore output in a certain period of time, which is obtained by accumulating the ore output per bucket of all records. This total amount data can help managers quickly understand the overall production scale in the period. For example, the total ore output of all shovels at various ore output locations in a month can be counted to evaluate whether the production progress of that month meets expectations.

[0047] The average output is calculated by calculating the average output per bucket of different shovels, different ore-discharging locations, and the entire mine. The average output can reflect the production efficiency level of different equipment and regions. For a specific shovel, the sum of the output of all its ore-discharging records is divided by the number of ore-discharging times to get the average output per bucket of the shovel. The same method can be used to calculate the average output of different ore-discharging locations. By comparing these average values, it is possible to find out which shovels and ore-discharging locations are more or less efficient, providing data support for shovel operation planning.

[0048] Fluctuation analysis is the analysis of the fluctuation of ore output over time. You can draw a line graph of ore output over time to observe whether there are obvious seasonal changes, cyclical changes or random fluctuations in ore output. For example, if you find that ore output has dropped significantly in a certain season, you may need to further investigate the reasons, such as whether weather conditions, equipment maintenance and other factors have affected production.

[0049] Comparative analysis is divided into comparison between shovels and comparison between mining locations. Comparison between shovels compares the output, working time, efficiency and other indicators of different shovels. A bar chart or table can be made to intuitively show the performance differences of each shovel. For example, compare the average output per bucket and working time of different types of shovels to evaluate which type of shovel performs better in production. At the same time, the failure rate and maintenance cost of different shovels can be analyzed to comprehensively consider and select the optimal shovel combination. Comparison between mining locations analyzes factors such as the output, ore quality, and mining difficulty of different mining locations. By comparing the output and quality of each location, resource-rich areas can be determined and the mining layout can be optimized. For example, for locations with large output and good ore quality, mining efforts can be increased; for locations with small output or high mining difficulty, you can consider reducing investment or looking for alternatives.

[0050] The correlation analysis is divided into the correlation analysis between the output and time and the correlation analysis between the output and the shovel number and the location of the output. The correlation analysis between the output and time can find out whether there is a difference in the output in a specific time period. For example, if the output is lower on weekends, the personnel arrangement or equipment maintenance plan can be adjusted to ensure efficient generation on weekdays. The correlation analysis between the output and the shovel number and the location of the output can analyze which shovels perform better at which locations, so as to facilitate more reasonable task allocation.

[0051] The final embodiment combines various analysis results to obtain mining analysis statistics, generates data tables, charts or graphs, and uses them to adjust and generate more reasonable shoveling operation strategies.

[0052] In summary, the method for measuring the output of a shovel loader provided by the present invention first obtains the three-dimensional scanning data of the ore pile; then generates three-dimensional point cloud data based on the three-dimensional scanning data, performs denoising preprocessing on the three-dimensional point cloud data to obtain denoised point cloud data, performs point cloud volume calculation on the denoised point cloud data to obtain ore pile volume data, determines the volume change of the ore pile based on the ore pile volume data, and determines the output of the shovel loader based on the volume change of the ore pile and preset ore density data.
