[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Conveyor belts are mechanized and automated conveying tools for material handling systems. In actual use, conveyor belt deviation is one of the most common faults during operation. There are many reasons for deviation. One of the main reasons is that when installing the conveyor belt, the installation accuracy is low, which leads to subsequent conveyor belt deviation. Another reason is that the daily maintenance and care of the conveyor belt is poor, which leads to conveyor belt deviation during use.

[0050] Currently, the existing methods for conveyor belt deviation correction include checking the misalignment between the lateral center line of the roller and the longitudinal center line of the belt conveyor, checking the deviation value of the two planes of the bearing seats installed on the head and tail frames, and checking the position of the material on the conveyor belt. However, the above methods all require tedious and complicated conveyor belt deviation correction detection on the transmission belt, and cannot detect conveyor belt deviation in a timely and sensitive manner.

[0051] In view of this, the present invention provides a conveyor belt deviation correction detection method, which obtains the edge line of the conveyor belt according to the conveyor belt area and the measuring handle, thereby simplifying the measurement method while ensuring the precision and accuracy of the measurement of the conveyor belt edge line. At the same time, the running state of the transmission belt is determined according to the edge line and the inner edge line of the conveyor belt bracket, thereby more flexible determination of the running state of the conveyor belt and more timely correction operation of the conveyor belt are achieved, thereby avoiding the loss of manpower and material resources and improving the efficiency of conveyor belt detection.

[0052] The following is a detailed description, please refer to Figure 1 , Figure 1 A flow chart of a conveyor belt deviation correction detection method provided by an embodiment of the present invention. A conveyor belt deviation correction detection method according to an embodiment of the present invention may include:

[0053] Step S101: Acquire image information, where the image information includes a conveyor belt bracket and a conveyor belt.

[0054] In the embodiment of the present invention, the image information is a picture containing information such as a conveyor belt bracket and a conveyor belt, and there is no limitation on the method of obtaining the image information. The image information can be obtained by using a camera to capture an image containing the conveyor belt, or by scanning the conveyor belt. It should be noted that in the embodiment of the present invention, the image information can be obtained in real time, or according to a preset time interval, and there is no limitation on this.

[0055] Step S102: Divide the image information according to the image information to obtain the conveyor belt area of ​​the conveyor belt.

[0056] In the embodiment of the present invention, since the acquired image information contains information such as the conveyor belt bracket and the conveyor belt, it is necessary to divide the image information and identify the conveyor belt area belonging to the conveyor belt in the image information to facilitate the subsequent determination of the operating status of the conveyor belt.

[0057] In the embodiment of the present invention, the image information can be divided according to the image information to obtain the conveyor belt area of ​​the conveyor belt, and the image information can be preprocessed to obtain a preprocessed image, and then the preprocessed image can be divided according to the preprocessed image to obtain the conveyor belt area. It should be noted that in the embodiment of the present invention, a threshold segmentation algorithm can be used to divide the preprocessed image to obtain the conveyor belt area. The specific process is to use the threshold segmentation algorithm to determine the area of ​​each area in the preprocessed image after division, and extract the area corresponding to the largest area as the conveyor belt area.

[0058] It should be noted that, in the embodiment of the present invention, the process of preprocessing the image information to obtain the preprocessed image can be to first use the image enhancement contrast algorithm to process the image information to obtain the enhanced image, and then perform color channel separation on the enhanced image to obtain the preprocessed image. The color channel separation can be to perform three-channel separation according to RGB (red, green, and blue color mode) to convert into three single-channel images, or it can be to directly convert the RGB image into a grayscale image, that is, to obtain only one grayscale image.

[0059] It should be noted that, in the embodiment of the present invention, the image information can be processed by using an image enhancement contrast algorithm to obtain an enhanced image. The process can be to first perform low-pass filtering on the image information, and then obtain the enhanced image based on the result of the low-pass filtering and the image information. Specifically, the image information can be low-pass filtered to obtain a first grayscale value, and the enhanced image including the second grayscale value can be obtained by using a formula based on the first grayscale value and the original grayscale value of the image information. The specific formula is as follows:

[0060] res:=round((orig-mean)×Factor+orig

[0061] Among them, res is the second grayscale value, orig is the original grayscale value, mean is the first grayscale value, Factor is the contrast enhancement parameter, and round is a basic function used to round the value according to the specified number of bits.

[0062] In the embodiment of the present invention, the image information is preprocessed to obtain a preprocessed image, and then the preprocessed image is divided according to the preprocessed image to obtain the conveyor belt area of ​​the conveyor belt, thereby achieving clearer identification of the conveyor belt area and facilitating subsequent more accurate determination of the operating status of the conveyor belt.

[0063] Step S103: Obtaining the edge line of the conveyor belt according to the conveyor belt area and the preset measurement handles.

[0064] In the embodiment of the present invention, the measuring handle is a tool for accurately measuring the edge line of the conveyor belt and the inner edge line of the conveyor belt bracket. The size, size, number and other information can be pre-set by the designer according to the needs, or can be set according to the actual usage scenario, without any restriction.

[0065] In the embodiment of the present invention, the edge line of the conveyor belt can be obtained according to the conveyor belt area and the preset measurement handle. It should be noted that in order to ensure the accuracy of the measurement, the conveyor belt edge line of the conveyor belt can be first determined according to the conveyor belt area, and the conveyor belt edge line can be marked to obtain the initial edge line, and then the measurement point set on the initial edge line can be determined according to the measurement handle, and the edge line can be obtained according to the measurement point set. Among them, in the embodiment of the present invention, the conveyor belt edge line of the conveyor belt can be determined according to the conveyor belt area, and the minimum circumscribed rectangle and the maximum inscribed rectangle in the conveyor belt area can be obtained, and the conveyor belt edge line can be determined according to the circumscribed rectangle and the inscribed rectangle. Among them, after obtaining the minimum circumscribed rectangle and the maximum inscribed rectangle, it can be determined whether the first vertex corresponding to the circumscribed rectangle and the second vertex corresponding to the inscribed rectangle are on the same side and whether the first vertex and the second vertex are the same. If the first vertex and the second vertex are on the same side and the first vertex and the second vertex are not the same, then a straight line is determined according to the first vertex and the second vertex, and the straight line is the conveyor belt edge line.

[0066] It should be noted that, in the embodiment of the present invention, after obtaining the edge line of the conveyor belt, the edge line of the conveyor belt can be marked to obtain the initial edge line, wherein the marking method is not limited, and a straight line can be directly created according to the points of the maximum inscribed rectangle and the minimum circumscribed rectangle, or a straight line can be manually drawn along the edge of the conveyor belt. Then, according to the measurement handle, the measurement point set on the initial edge line is determined, and the edge line is obtained according to the measurement point set. For example, n measurement handles can be set, and the initial edge line can be measured using the measurement handles to obtain a corresponding measurement point set containing n points. According to the measurement data of each point in the measurement point set, it is connected and fitted into a straight line, and the straight line is the edge line of the conveyor belt. Among them, there is no limit on the number of measurement handles, which can be set by the designer according to the needs, and can also be set according to the actual usage scenario.

[0067] In the embodiment of the present invention, the edge line of the conveyor belt is obtained according to the conveyor belt area and the preset measurement handle, and the edge line is determined using the measurement handle, so that the edge line of the conveyor belt can be determined more accurately, thereby improving the accuracy of determining the edge line.

[0068] Step S104: Determine the running state of the transmission belt according to the edge line and the inner edge line of the conveyor belt bracket.

[0069] In the embodiment of the present invention, the running state may include a deviation running state and a normal running state, and the running state of the transmission belt may be determined according to the edge line and the inner edge line of the conveyor belt bracket. The numerical range of the angle may be determined according to the angle between the edge line and the inner edge line, and then the running state of the transmission belt may be determined according to the numerical range. It should be noted that, in order to facilitate the calculation of the value of the angle, it may be determined whether the edge line and the inner edge line of the conveyor belt bracket are on the same side first, and if they are on the same side, the numerical range of the angle may be determined according to the angle between the edge line and the inner edge line, and then the running state of the transmission belt may be determined according to the numerical range. If they are not on the same side, the inner edge line of the conveyor belt bracket on the same side of the edge line is obtained, and the numerical range of the angle may be determined according to the angle between the edge line and the inner edge line, and then the running state of the transmission belt may be determined according to the numerical range.

[0070] It should be noted that in the embodiment of the present invention, the running state of the transmission belt can be determined according to the numerical range, and the numerical range can be set as a deviation range. When the numerical value of the angle is in the deviation range, the conveyor belt is in a deviated running state at this time, and when the numerical value of the angle is not in the deviation range, the conveyor belt is in a normal running state at this time. The numerical range can also be set as a normal range. When the numerical value of the angle is in the normal range, the conveyor belt is in a normal running state at this time, and when the numerical value of the angle is not in the normal range, the conveyor belt is in a deviated running state at this time, and there is no restriction on this. Among them, there is no restriction on the interval numerical setting of the numerical range, which can be set by the designer according to the needs, and can also be set according to the actual use scenario.

[0071] It should be noted that in the embodiment of the present invention, the measurement operation of the inner edge line can be performed simultaneously with the measurement operation of the edge line. The specific process can be based on the inflection point detection, the coordinates of the four points of the conveyor belt bracket are obtained, and the inner edge line of the conveyor belt bracket is calibrated according to the coordinates of the two points on the inner side of the conveyor belt bracket to obtain the initial inner edge line, and then the measurement point set of the initial inner edge line is determined according to the measurement handle, and the inner edge line is obtained according to the measurement point set. For example, n measurement handles can be set, and the initial inner edge line can be measured using the measurement handles to obtain a corresponding measurement point set containing n points. According to the measurement data of each point in the measurement point set, it is connected and fitted into a straight line, and the straight line is the inner edge line of the conveyor belt bracket. Among them, there is no restriction on the number of measurement handles, which can be set by the designer according to the needs, and can also be set according to the actual usage scenario.

[0072] In the embodiment of the present invention, the operating state of the transmission belt is determined according to the edge line and the inner edge line of the conveyor belt bracket, so that the operating state of the conveyor belt can be determined more conveniently and efficiently, thereby improving the efficiency of determining the operating state of the conveyor belt.

[0073] Based on the above embodiments, an embodiment of the present invention provides a conveyor belt deviation correction detection method, which obtains the edge line of the conveyor belt according to the conveyor belt area and the measuring handle, thereby simplifying the measurement method while ensuring the precision and accuracy of the measurement of the edge line of the conveyor belt. At the same time, according to the edge line and the inner edge line of the conveyor belt bracket, the running state of the transmission belt is determined, thereby more flexible determination of the running state of the conveyor belt and more timely correction operation of the conveyor belt are achieved, thereby avoiding the loss of manpower and material resources and improving the efficiency of conveyor belt detection.

[0074] The following is a specific example to illustrate the above process, please refer to Figure 2 , Figure 2 A flowchart of a specific conveyor belt deviation correction detection method provided by an embodiment of the present invention may include:

[0075] Step S201: Acquire image information, where the image information includes a conveyor belt bracket and a conveyor belt.

[0076] For the specific content of the above step S201, reference may be made to the corresponding content disclosed in the above embodiment, and no further description will be given here. It should be noted that in the embodiment of the present invention, the following may be obtained: Figure 3 The image information shown includes a conveyor belt bracket and a conveyor belt.

[0077] Step S202: using an image enhancement contrast algorithm to process the image information to obtain an enhanced image.

[0078] Step S203: performing color channel separation on the enhanced image to obtain a preprocessed image.

[0079] Step S204: According to the pre-processed image, a threshold segmentation algorithm is used to divide the pre-processed image to obtain a conveyor belt area.

[0080] In the embodiment of the present invention, a threshold segmentation algorithm can be used to divide the pre-processed image into the following Figure 4 The conveyor belt area shown, where Figure 4 The parallelogram area in the middle is the conveyor belt area.

[0081] Step S205: Determine the conveyor belt edge line of the conveyor belt according to the conveyor belt area, mark the conveyor belt edge line to obtain an initial edge line, and mark the edge line of the conveyor belt bracket to obtain an initial inner edge line.

[0082] In the embodiment of the present invention, the conveyor belt edge line of the conveyor belt can be determined according to the conveyor belt area. For example, the conveyor belt area can be analyzed to obtain the conveyor belt area. Figure 5 The minimum circumscribed rectangle shown and Figure 6The maximum inscribed rectangle shown is used to determine the first vertex corresponding to the circumscribed rectangle and the second vertex corresponding to the inscribed rectangle. A straight line is determined based on the first vertex and the second vertex, and the straight line is the edge line of the conveyor belt.

[0083] In the embodiment of the present invention, the coordinates of four points of the conveyor belt bracket can be obtained based on the inflection point detection, and the inner edge line of the conveyor belt bracket can be calibrated according to the coordinates of two points on the inner side of the conveyor belt bracket to obtain the initial inner edge line.

[0084] Step S206: Determine the measurement point set on the initial edge line according to the measurement handle, and obtain the edge line according to the measurement point set, and determine the measurement point set of the initial inner edge line, and obtain the inner edge line according to the measurement point set.

[0085] In the embodiment of the present invention, the following can be used Figure 7 The measurement handles shown measure the initial edge line of the conveyor belt and the initial inner edge line of the conveyor belt bracket to obtain the edge line and the inner edge line. The shape of the measurement handle is a rectangular measurement area, the number is set to 10, the length of the rectangular box is set to 40 pixels, the width is set to 10 pixels, and the minimum edge amplitude is set to 50.

[0086] Step S207: Determine the running state of the transmission belt according to the edge line and the inner edge line of the conveyor belt bracket.

[0087] In the embodiment of the present invention, the numerical range of the angle can be determined based on the angle between the edge line and the inner edge line, and then the running state of the transmission belt can be determined based on the numerical range. Specifically, for example, the numerical range can be set to a normal range, such as the normal range is set to -0.0825≤a≤0.0825, a is the value of the angle, when the value of the angle (a) is within the normal range, the conveyor belt is in a normal running state, when the value of the angle is not within the normal range, that is, a<-0.0825 or a>0.0825, the conveyor belt is in a deviated running state.

[0088] In the embodiment of the present invention, the edge line of the conveyor belt is obtained according to the conveyor belt area and the measuring handle, which simplifies the measurement method while ensuring the precision and accuracy of the measurement of the edge line of the conveyor belt. At the same time, the running state of the transmission belt is determined according to the edge line and the inner edge line of the conveyor belt bracket, which makes it possible to more flexibly determine the running state of the conveyor belt and more timely correct the deviation of the conveyor belt, thereby avoiding the loss of manpower and material resources and improving the efficiency of conveyor belt detection.
