In order to enable the hyperspectral image to obtain a better display effect, smoothing processing and normalization transformation processing can be carried out on the hyperspectral image to be identified.
The method proposed by the present invention is described below with reference to an example:
101. and imaging the coal blocks and the rocks to obtain a hyperspectral image.
In this example, the hyperspectral image is obtained by imaging the coal rock flow with a hyperspectral camera. The hyperspectral camera may be: near infrared and short wave infrared cameras. The coal rock stream may be a coal block, rock block, or a coal block-rock mixture stream transported on a conveyor belt.
In some embodiments of the present invention, after imaging the coal and rock with the hyperspectral camera to obtain the hyperspectral image, the hyperspectral image may be processed with viewspec software and MATLAB software, and the specific processing may be preprocessing of hyperspectral data of each pixel point of the image, for example, smoothing and normalization transform processing of the hyperspectral data. The specific steps can be as follows: and opening an image file corresponding to the hyperspectral image by using the viewspec software, converting the image file into an ASCII code form, importing the ASCII code form into an EXCEL form, and processing the EXCEL form data by using MATLAB to obtain a processed hyperspectral image.
Wherein, MATLAB is a commercial mathematical software produced by MathWorks corporation in usa, MATLAB is a combination of two words of matrix & laboratory, which means a matrix factory (matrix laboratory), and the software mainly faces a high-tech computing environment of scientific computing, visualization and interactive programming.
In some embodiments of the invention, the scheme further comprises: the hyperspectral data is preprocessed in MATLAB software by using a preset preprocessing method, and the preprocessing method can comprise smoothing processing and normalization transformation processing. It should be understood that the hyper-spectral image is subjected to smoothing processing and normalized transformation processing, so that a better display effect of the hyper-spectral image can be obtained.
The hyperspectral camera is equipment which can image a target on hundreds of imaging channels through a hyperspectral technology, wherein one imaging channel corresponds to one wave band; the hyperspectral camera has the advantages of small influence by the surface moisture of an object, small volume and convenient installation and debugging, so that the hyperspectral camera can be conveniently operated under or on a coal mine.
Because the hyperspectral camera is provided with hundreds of imaging channels, one imaging channel corresponds to one wave band, all the channels cannot be used when imaging the coal blocks and the rocks, and partial channels can be selected for imaging. In some embodiments of the present application, the partial imaging channel in the hyperspectral image includes: imaging channels corresponding to a plurality of wave bands of the coal and the rock can be distinguished, and the wave bands correspond to the imaging channels one to one. In this kind of embodiment, the imaging channel is the imaging channel that a plurality of wave bands that can distinguish coal and rock correspond, explains that the imaging channel has the effect of discernment coal and rock, and the high spectral image that obtains based on this kind of imaging channel reuses the target classifier and classifies coal and rock, can further improve the discernment accuracy, promotes coal petrography separation efficiency.
Specifically, one way to determine the imaging channel may include the following operations: step 1, imaging the coal briquette by using all imaging channels in a hyperspectral camera to obtain a hyperspectral image of the coal briquette; step 2, imaging the rock by using all imaging channels in the hyperspectral camera to obtain a hyperspectral image of the rock; step 3, comparing and classifying the hyperspectral images of the coal blocks of the same imaging channel with the hyperspectral images of the rocks to obtain a classification precision table; and 4, determining the imaging channel with the highest precision in the classification precision table as a target imaging channel.
102. And performing coal-rock classification on the hyperspectral image based on a coal-rock classification model obtained by pre-training to obtain the type of each pixel in the hyperspectral image.
The coal-rock classification model is obtained based on training of a pre-labeled training sample, the training sample comprises coal flow images obtained by imaging of a plurality of hyperspectral cameras in a mining area, and the types of the coal-rock classification model comprise coal blocks, rocks and belts. As a better two-classification model at present, a coal-rock classification model adopts a Support Vector Machine (SVM) for classification. Taking the Viewspec software and the MATLAB software as examples, ASCII code conversion is performed on a target image in the Viewspec software, SVM recognition is performed on the ASCII code of the target image by using the MATLAB software, three categories of coal blocks, rocks and belts are established, and an SVM is used for recognition according to the divided categories.
It should be understood that each pixel point in the hyperspectral image is classified by using the coal-rock classification model, and the category to which each pixel point belongs is determined to be coal, rock or belt. Of course, if there is a pixel that is not in the above three categories, the pixel is marked as a category that cannot be identified.
In addition, it is easy to understand that the coal-rock classification model can only identify the position information of one of the coal block and the rock block or can identify both the coal block and the rock block at the same time according to the requirements of different application scenarios. For example, in a coal preparation plant, the coal blocks need to be continuously conveyed to the coal bunker on the coal flow conveyor belt, and at the moment, the purpose of sorting the rock blocks from the coal flow conveyor belt can be achieved only by identifying the rock blocks and the position information of the rock blocks.
103. And acquiring the position information of the object profile based on the object profile and the type information of the object to be sorted.
After the classification of each pixel point is obtained by using the coal-rock classification model, all the pixel points of the classification of the coal and all the pixel points of the classification of the rock in the hyperspectral image are obtained. Therefore, the coal-rock classification model can obtain the classification result, namely the distribution of the coal blocks and the rock blocks in the hyperspectral image.
And performing edge detection on the hyperspectral image and the outline of the object to be identified by adopting a Robert edge detection algorithm to obtain the outline of the object to be identified and determine the position areas of the coal blocks and the rock blocks in the hyperspectral image.
And obtaining the mass centers of the coal blocks and the rock blocks by using a mass center method, determining mass center coordinates, and taking the mass center coordinates as the position information of the coal blocks and the rock blocks in the target image.
After the identification result of the coal and/or rock is obtained, the coal and/or rock needs to be positioned so as to facilitate the subsequent sorting step. Firstly, the outline of the coal block and the rock is obtained by Robert edge detection, and the position area of the coal block and the rock in the target image is determined. Then, the centroid method is used to obtain the centroid of the location area and determine the centroid coordinates. And finally, taking the centroid coordinates as the position information of the coal blocks and the rock blocks in the target image. This allows for the positioning of the coal and/or rock in the target image.
104. And controlling the mechanical arm to perform sorting operation according to the position information of the coal blocks and/or the rock blocks so as to sort the coal blocks and the rock blocks.
In this step, it may be selected to sort the coal blocks or the rock blocks individually, that is, to decide whether the robot arm grabs the coal blocks or the rock blocks, for example, if we let the robot arm grab the rock blocks, the coordinate position of the identified rock block needs to be sent to the robot arm, and then the robot arm receives the coordinate position and converts it into the corresponding coordinate position in the coordinate system of the robot arm itself. And then, giving an advanced coordinate deviation delta X to the mechanical arm according to the moving speed of the belt and the time required by the mechanical arm to move to the designated grabbing position, and controlling the mechanical arm to grab according to the coordinate position and the coordinate deviation delta X. For example: if a rock block is identified, the pixel coordinate position of the rock block in the hyperspectral image is (X1, Y1), then the mechanical arm converts the pixel coordinate position into the coordinate (X1, Y1) of the coordinate system of the mechanical arm, then the moving time of the belt and the arm is considered comprehensively, and finally the mechanical arm needs to move from the initial position to the coordinate (X1+ delta X, Y1) to execute the grabbing action, wherein the abscissa X of the coordinate represents the moving direction of the belt, and the ordinate Y represents the vertical direction of the moving direction of the belt. The mechanical arm grabs the rock to the belt of the running rock, and the coal is still left on the coal flow belt, so that the task of sorting the coal and the rock by using the mechanical arm once is completed.
In the embodiment, different spectral characteristic information is shown due to different components of the coal briquette and the rock and different absorption of different components to the spectrum, so that the coal briquette and the rock can be distinguished according to the target imaging channel determined according to the spectral image characteristic information of the coal briquette and the rock; secondly, recognizing the hyperspectral images of the coal flow by using a target recognition model, wherein the target recognition model is obtained by performing data training on the hyperspectral images of the coal blocks and the rocks, and recognizing the position information of the coal blocks and the rocks by using a big data mode; consequently, use the different characteristics of spectral image characteristic that utilizes both to demonstrate of coal cinder and rock in this application to the mode of training with a large amount of data is discerned coal cinder and rock, can effectually avoid under the coal stream environment the influence of environmental factor such as dust and moisture, thereby accurately discerning coal cinder and rock, improves the degree of accuracy that coal cinder and rock were selected separately, further improves the efficiency that coal cinder and rock were selected separately.
