Description

Technical Field

[0001] The present invention relates to the field of computer technology application technology, and in particular to a vehicle release control method, system and medium for a stone material station. Background Art

[0002] The existing stone transport supervision for transport vehicles in stone factories and stations is generally direct entry and exit. It only needs to be confirmed by the weigher, driver and supervisor to determine the weight of the current transport vehicle before it can be released. In this way, when the vehicle driver enters the station, he needs to get off the vehicle and go to the weighing room to inform the weigher of his vehicle number, the materials being transported, and whether the vehicle is loaded or empty. The weigher reads the readings shown on the scale display screen, and the weigher issues the corresponding bill. After the weigher, driver and supervisor sign, the vehicle directly leaves the station. This method involves a lot of manual participation, and there is no need for safety inspections when vehicles enter and exit, so it is impossible to effectively supervise vehicles transporting stone. In particular, stone is a cargo that is extremely easy to generate dust and is easy to slide out of the carriage due to uneven ground. When transporting stone, it is generally necessary to use tarpaulins and other measures to cover and fix the stone to prevent it from falling. Therefore, it is necessary to check whether the transport vehicle is protected when it leaves the station.

[0003] Therefore, there is an urgent need for a method that can automatically supervise the release of transport vehicles at stone sites. Summary of the invention

[0004] The purpose of the present invention is to provide a vehicle release control method, system and medium for a stone quarry station, which realizes automatic supervision of vehicles by calling the vehicle cargo information and protection information of the vehicle to be released for safety inspection. When the vehicle cargo information passes and the protection inspection passes, the exit electric pole is controlled to release the current vehicle to be released.

[0005] To achieve the above objectives, this application provides the following solutions: On the one hand, the present invention provides a vehicle release control method for a stone material station, which specifically comprises the following steps: S1. Obtaining the cargo information of the vehicle to be released, and obtaining a body picture of the vehicle to be released; S2. Perform vehicle information check on the vehicle to be released using the vehicle cargo information, and perform protection check on the vehicle to be released using the vehicle body picture, wherein the method for performing protection check based on the vehicle body picture is: Obtain the empty vehicle picture taken at the entrance corresponding to the vehicle to be released, input the vehicle body picture and the empty vehicle picture into the graphic recognition model, and annotate the vehicle body picture with the empty vehicle picture as the reference to obtain the image to be recognized with shape area annotation; Compare the colors of the shape areas in the image to be recognized. If the colors are consistent, the protection inspection is considered to have passed. If the colors are inconsistent, the protection inspection is considered to have failed. S3. When the vehicle information check and the protection check are passed at the same time, the exit electric lever is controlled to release the vehicle currently to be released.

[0006] In some specific implementation schemes, in step S2, the vehicle body image includes a vehicle body side image, and the shape area includes a rectangular compartment part and a special-shaped cargo part. The specific process of color comparison of each shape area in the image to be identified is: When the color of the rectangular carriage part is the same as the color of the special-shaped cargo part, the protection inspection is judged to have passed; When the color of the rectangular carriage part is different from the color of the special-shaped cargo part, it is judged that the protection inspection has failed.

[0007] In some specific implementation schemes, the vehicle body picture includes a vehicle body side image and a vehicle top image, and the method for performing protection inspection based on the vehicle body picture is specifically as follows: The side image and the top image of the vehicle body are respectively input into the graphic recognition model for graphic annotation, so as to obtain the side image to be identified and the top image to be identified with shape area annotation; When the shape area of ​​the side image to be identified only includes the rectangular carriage part, the shape area of ​​the top image to be identified includes the rectangular cargo part. The colors of the rectangular carriage part and the rectangular cargo part are compared to see if they are consistent. If the colors are consistent, it is determined that the protection inspection has passed.

[0008] In some specific embodiments, when the side image to be identified includes a rectangular carriage part and a special-shaped cargo part, first compare whether the colors of the rectangular carriage part and the special-shaped cargo part are consistent. If the colors of the rectangular carriage part and the special-shaped cargo part are consistent, it is determined that the protection inspection has passed; If the colors of the rectangular carriage part and the irregular cargo part are inconsistent, continue to determine whether the colors of the irregular cargo part and the rectangular cargo part are consistent; When the colors of the irregular cargo part and the rectangular cargo part are the same, it is judged that the protection inspection has passed.

[0009] In some specific embodiments, when the rectangular carriage portion and the rectangular cargo portion have the same color, the method further includes the steps of: Cut out a rectangular cargo part image from the top image to be recognized, and convert the rectangular cargo part image into a grayscale image; The pixel points in the grayscale image are divided into columns according to the pixel coordinates, and each column is along the direction perpendicular to the front of the vehicle, and multiple columns of continuous pixel data are obtained. A column of pixel data is composed of pixel points with the same horizontal coordinate; Obtain the grayscale values ​​of all pixels in the pixel data, calculate each column of pixel data, calculate the average grayscale value of the pixels in the pixel data, and use the average value as the corresponding chromaticity value; Whether the rectangular cargo portion is completely covered is determined based on the chromaticity value between two adjacent columns of pixel data in the grayscale image.

[0010] In some specific implementation schemes, the process of determining whether the image of the rectangular cargo portion is completely covered according to the chromaticity value between two adjacent columns of pixel data in the grayscale image is as follows: Obtain the chromaticity value of each column of pixel data in the grayscale image, traverse the chromaticity value of each column of pixel data in the grayscale image by window moving traversal, set the window length to two, and the step value of each movement to one; Compare whether the chromaticity values ​​of two adjacent columns of pixel data in the window are both within the same preset chromaticity value range. If so, store the current two columns of pixel point data in the same area; if not, store the current two columns of pixel point data in different areas respectively; Move the window to obtain the chromaticity values ​​of the next two adjacent columns of pixel data for comparison until every column of pixel data in the grayscale image is traversed; When the number of regions is greater than or equal to 2, it is determined that the rectangular cargo portion is not completely covered.

[0011] In some specific implementation schemes, vehicle cargo information includes vehicle entry detection information collected from vehicles with the same license plate information and at similar times passing through the entry scale, and vehicle exit detection information collected from vehicles passing through the exit scale; the vehicle entry detection information includes entry time, license plate information, empty vehicle weight, vehicle load and type of transported materials, and the vehicle exit detection information includes arrival at the exit time, license plate information, loading weight and type of transported materials.

[0012] In some specific implementation schemes, the specific process of vehicle information checking is: Compare whether the type of materials transported in the vehicle entry detection information is consistent with the type of materials transported in the vehicle exit detection information. At the same time, determine whether the vehicle is overloaded by comparing the loading weight with the vehicle load. If the type of materials transported is consistent and the vehicle is not overloaded, the vehicle information inspection is judged to have passed.

[0013] In a second aspect, the present application provides a vehicle release control system for a stone material station, comprising: An information acquisition module is used to call the vehicle cargo information of the vehicle to be released from the vehicle information management center, and obtain the body picture of the vehicle to be released from the monitoring equipment facing the vehicle; The vehicle information checking module is used to check the vehicle information of the vehicle to be released by using the vehicle cargo information; The protection inspection module is used to perform a protection inspection on the vehicle to be released using the vehicle body picture; The protection inspection is as follows: obtain the empty vehicle picture taken at the entrance corresponding to the vehicle to be released, input the body picture and the empty vehicle picture into the graphic recognition model, and annotate the body picture with the empty vehicle picture as the reference to obtain the image to be recognized with shape area annotation; The safety release module is used to control the exit electric lever to release the vehicle currently to be released when the vehicle information check and protection check are passed at the same time.

[0014] In a third aspect, the present application provides a computer-readable storage medium, comprising: one or more processors; A storage unit is used to store one or more programs.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. 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.

[0018] The relative arrangement of components and steps, the numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise.

[0019] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0020] Additionally, descriptions of well-known structures, functions, and configurations may be omitted for clarity and conciseness.One of ordinary skill in the art will recognize that various changes and modifications may be made to the examples described herein without departing from the spirit and scope of the present disclosure.

[0021] Technologies, methods, and apparatus known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, such technologies, methods, and apparatus should be considered part of the authorization specification.

[0022] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0023] Example 1 like Figure 1 As shown, this embodiment provides a vehicle release control method for a stone material station, which specifically includes the following steps: S1. Obtaining the cargo information of the vehicle to be released, and obtaining a body picture of the vehicle to be released; It is understandable that when taking the body picture of the vehicle to be released, it is obtained from the monitoring equipment that is directly to the side of the vehicle to be released and can take a picture of the top of the vehicle to be released; S2. Use the vehicle cargo information to check the vehicle information of the vehicle to be released, and use the vehicle body picture to perform a protection check on the vehicle to be released, wherein: S21. The method for conducting protection inspection based on the vehicle body picture is: Obtain the empty vehicle picture taken at the entrance corresponding to the vehicle to be released, input the vehicle body picture and the empty vehicle picture into the graphic recognition model, and annotate the vehicle body picture with the empty vehicle picture as the reference to obtain the image to be recognized with shape area annotation; Compare the colors of the shape areas in the image to be recognized. If the colors are consistent, the protection inspection is considered to have passed. If the colors are inconsistent, the protection inspection is considered to have failed. Since the transport vehicles for transporting stones are generally dump trailers, the carriages of such trucks can be turned sideways or backwards to unload, and the top of the carriage is generally open, which is convenient for quick loading and unloading of stones. The problem caused by this is that after the loading and unloading of stones is completed, it is easy for the stones to be higher than the carriage, and the stones are easy to fall due to bumps during the transportation of the vehicle. At the same time, there is a lot of dust in the untreated stones, which is also easy to produce a lot of dust during transportation and pollute the environment along the road. The existing, generally most economical and practical method is to cover and fix the top of the carriage with a tarpaulin. The tarpaulin generally needs to cover the entire top of the carriage and be fixed on the frame of the carriage, and cover the stones protruding from the carriage. The more common method is to cover the sides and top of the entire carriage with a tarpaulin, which can protect the stones in the carriage and prevent them from falling or dust. Therefore, when the vehicle leaves the stone factory, it is necessary to check whether the vehicle effectively protects the carriage. Since the color of the tarpaulin is usually bright and different from the color of the carriage, and the stone is usually gray, it is easy to identify whether the carriage is covered with a tarpaulin by color, including the following situations: When the stones are too much and exceed the compartment part of the vehicle body, it can be clearly seen from the image taken from the side of the vehicle that it is divided into the compartment part and the stone part. Through the trained image recognition model of the vehicle body, the image recognition model can recognize the compartment part of the truck, so that the body part and the stone part of the vehicle body picture can be marked. For the side image of the vehicle body, the body part is generally rectangular, and the protruding part of the stone is generally irregular, which may be a pile of multiple triangular stones, or a pile of stones without a fixed shape. There is also a situation where the stones loaded on the vehicle do not exceed the compartment part of the vehicle body, and the image recognition model can only recognize the rectangular compartment part. At this time, it is necessary to combine the image of the top of the compartment to determine whether the compartment is covered with a tarpaulin. Alternatively, the image recognition model can be: the side image of the empty vehicle taken from the side of the vehicle when the vehicle enters from the entrance is stored in the original data set, and when the vehicle needs to leave, the side image of the vehicle body taken at the exit of the vehicle with the same license plate information is obtained, and the monitoring position of the empty vehicle side image of the vehicle corresponds to the shooting position of the side image of the vehicle body, so that the two pictures taken correspond to each other. For example, it can be installed at the position opposite to the side of the vehicle in the weighing room, and the background subtraction method is used to compare the side image of the empty vehicle and the side image of the vehicle body. The shape areas corresponding to the carriage part and the stone part can be marked in the side image of the vehicle body, which are respectively a rectangular carriage part and a special-shaped cargo part. This method can accurately obtain the area where the vehicle has changed, and quickly identify the carriage and stone parts. Specifically: 1. If Figure 3-Figure 4 As shown, the vehicle body picture includes a side image of the vehicle body. When the image recognition model recognizes the side image of the vehicle body, the shape area in the recognition result includes a rectangular compartment part and a special-shaped cargo part. The colors of the rectangular compartment part and the special-shaped cargo part can distinguish whether the vehicle is covered. The specific process of color comparison of each shape area in the image to be recognized is as follows: When the color of the rectangular carriage part is the same as the color of the special-shaped cargo part, the protection inspection is judged to have passed; When the color of the rectangular carriage part is different from the color of the special-shaped cargo part, it is judged that the protection inspection has failed.

[0024] 2. When the image recognition model recognizes the side image of the vehicle body, and the shape area in the recognition result only includes the rectangular car body part, the top image of the vehicle body is called, and the side image and the top image of the vehicle body are respectively input into the graphic recognition model for graphic annotation, so as to obtain the side image to be identified and the top image to be identified with shape area annotation; When the shape area of ​​the side image to be identified only includes the rectangular carriage part, the shape area of ​​the top image to be identified includes the rectangular cargo part. The colors of the rectangular carriage part and the rectangular cargo part are compared to see if they are consistent. If the colors are consistent, it is determined that the protection inspection has passed.

[0025] 3. In order to avoid the situation where the tarpaulin is too short and can only cover the top of the carriage and the stones protruding from the carriage when the stone particle size is large, that is, when the side of the carriage is not covered, the judgment is made in combination with the side image and the top image of the vehicle body: 3.1. When the side image to be identified includes a rectangular carriage part and a special-shaped cargo part, first compare whether the colors of the rectangular carriage part and the special-shaped cargo part are consistent. If the colors of the rectangular carriage part and the special-shaped cargo part are consistent, it is determined that the protection inspection has passed; 3.2. If the colors of the rectangular carriage part and the irregular cargo part are inconsistent, continue to determine whether the colors of the irregular cargo part and the rectangular cargo part are consistent; 3.3. When the colors of the irregular cargo part and the rectangular cargo part are the same, the protection inspection is considered to have passed.

[0026] It is understandable that the color judgment mentioned in this article can be RGB value judgment or grayscale value judgment. Since the color of the tarpaulin, the color of the carriage and the color of the stone are relatively uniform and the color difference is large, such as the color of the carriage is generally red, blue, etc., the color of the tarpaulin is generally gray, green, etc., and the color of the stone is gray, they can be distinguished by color. When comparing the colors of each shape area, the color average of the entire shape area is generally used as the color of the entire shape area, and the color consistency in this application is consistent within the allowable error range. Therefore, if there is incomplete coverage, it is easy to miss the judgment. Therefore, in order to avoid incomplete coverage, the following steps are also included: 4.1. Cut out the rectangular cargo part image from the top image to be identified, and convert the rectangular cargo part image into a grayscale image; The pixel points in the grayscale image are divided into columns according to the pixel coordinates. Each column is along the direction perpendicular to the front of the vehicle. Multiple columns of continuous pixel data are obtained. A column of pixel data is composed of pixel points with the same horizontal coordinate. The upper left corner of the grayscale image is taken as the origin, the direction parallel to the front of the vehicle is taken as the horizontal coordinate, and the direction perpendicular to the front of the vehicle is taken as the column. 4.2. Obtain the grayscale values ​​of all pixels in the pixel data, calculate each column of pixel data, calculate the average value of the grayscale values ​​of the pixels in the pixel data, and use the average value as the corresponding chromaticity value; 4.3. Determine whether the rectangular cargo portion is completely covered based on the chromaticity value between two adjacent columns of pixel data in the grayscale image.

[0027] 4.3.1. Obtain the chromaticity value of each column of pixel data in the grayscale image, and traverse the chromaticity value of each column of pixel data in the grayscale image by window moving traversal, setting the window length to two and the step value of each movement to one; 4.3.2. Compare whether the chromaticity values ​​of two adjacent columns of pixel data in the window are within the same preset chromaticity value range. If so, store the current two columns of pixel point data in the same area. If not, store the current two columns of pixel point data in different areas respectively. 4.3.3. Move the window to obtain the chromaticity values ​​of the next two adjacent columns of pixel data for comparison until every column of pixel data in the grayscale image is traversed; 4.3.4 When the number of regions is greater than or equal to 2, it is determined that the rectangular cargo portion is not completely covered.

[0028] Whether the carriage is covered is determined entirely by the image of the rectangular cargo part of the roof image. When there are multiple color partitions in the rectangular cargo part, it means that the carriage is not completely covered (the tarpaulin considered in this article is a solid color tarpaulin).

[0029] S22. Use the vehicle cargo information to check the vehicle information of the vehicle to be released. The specific process of the vehicle information check is as follows: In order to ensure that the type of goods transported by the vehicle and the vehicle load can pass the safety inspection throughout the process, Vehicle cargo information includes vehicle entry detection information collected from vehicles with the same license plate information and at similar times passing through the entrance scale, and vehicle exit detection information collected from vehicles passing through the exit scale; vehicle entry detection information includes entry time, license plate information, empty vehicle weight, vehicle load and type of transported materials, and vehicle exit detection information includes arrival at the exit time, license plate information, loading weight and type of transported materials.

[0030] Compare whether the type of materials transported in the vehicle entry detection information is consistent with the type of materials transported in the vehicle exit detection information. At the same time, determine whether the vehicle is overloaded by comparing the loading weight with the vehicle load. If the type of materials transported is consistent and the vehicle is not overloaded, the vehicle information inspection is judged to have passed.

[0031] S3. When the vehicle information check and the protection check are passed at the same time, the exit electric lever is controlled to release the vehicle currently to be released.

[0032] like Figure 2As shown, the scene of the stone quarry station in this embodiment is to separate the station entrance and exit, and control the exit electric pole to release the vehicle. The entrance weighing equipment and the exit weighing equipment are respectively arranged on both sides of the weighing room, and the entrance weighing equipment and the exit weighing equipment are respectively arranged corresponding to the entrance direction and the exit direction. The computer in the weighing room is deployed with an information management system and a vehicle release control system, and the entrance weighing equipment, the exit weighing equipment, and the monitoring equipment in the stone quarry station are all connected to the information management system, and the information management system and the vehicle release control system are connected in communication. Specifically, after a vehicle enters the stone material station from the station entrance, the vehicle passes through the entrance weighbridge equipment. Both the entrance weighbridge equipment and the exit weighbridge equipment include a weighbridge, a monitoring device and a display screen. The entrance weighbridge equipment can collect and record the entry time, license plate information, empty vehicle weight, vehicle load and type of material being transported (the material type can be actively informed by the driver or set according to the historical material loading situation of the vehicle) of the transport vehicle and store them in the vehicle entrance detection table. After the vehicle leaves the entrance weighbridge equipment, the driving trajectory of the vehicle in the stone material station is tracked, and the monitoring video of the monitoring device in the stone material area within a preset time after the vehicle leaves the weighbridge equipment is obtained. According to the monitoring video captured by the monitoring device after the vehicle enters the stone material area, since the vehicle generally reverses into the stone material area when loading stone, the license plate number of the vehicle and the type of material in the stone material area reversed into are obtained through analysis of the monitoring video, and the license plate number, material type and loading time of the vehicle are returned to the management system and filled in the vehicle exit detection table. All fields in the vehicle exit detection table are regarded as one piece of data. When a vehicle passes through the export weighbridge equipment, the export weighbridge equipment can collect and record the time of arrival of the transport vehicle at the export, license plate information, and loading weight, and find the data with the same license plate number in the vehicle export inspection table to complete the vehicle export inspection table. At the same time, the latest entry inspection information in the vehicle entry inspection table is called according to the license plate information and the time of arrival at the export. First, check whether the vehicle is overweight and whether the type of loaded materials is consistent. When the type of transported materials is consistent and the vehicle is not overloaded, the vehicle information check is judged to have passed and returned to the vehicle release control system. Then, the export inspection information and the entry inspection information are merged to obtain the vehicle information, and the material load is calculated according to the empty vehicle mass and the loading weight, and the amount is calculated according to the material load and material type. The generated amount can be returned to the vehicle release control system; Then the vehicle release control system reads the license plate information of the vehicle to be released, and reads the vehicle information inspection results from the information management system. It then calls the monitoring equipment installed in the station that can take pictures of the side and top of the vehicle to obtain the body picture, and performs a protection inspection based on the body picture. When the vehicle information inspection and the body protection inspection are passed, additional criteria can be added to control the exit electric pole to release the current vehicle to be released if the checkout has been completed.

[0033] Example 2 This embodiment provides a vehicle release control system for a stone material station, including: An information acquisition module is used to call the vehicle cargo information of the vehicle to be released from the vehicle information management center, and obtain the body picture of the vehicle to be released from the monitoring equipment facing the vehicle; The vehicle information checking module is used to check the vehicle information of the vehicle to be released by using the vehicle cargo information; The protection inspection module is used to perform a protection inspection on the vehicle to be released using the vehicle body picture; The protection inspection is as follows: obtain the empty vehicle picture taken at the entrance corresponding to the vehicle to be released, input the body picture and the empty vehicle picture into the graphic recognition model, and annotate the body picture with the empty vehicle picture as the reference to obtain the image to be recognized with shape area annotation; Compare the colors of the shape areas in the image to be recognized. If the colors are consistent, the protection inspection is considered to have passed. If the colors are inconsistent, the protection inspection is considered to have failed.
