Description

Technical Field

[0001] The present invention relates to the technical field of computer technology applications, and particularly relates to a vehicle release control method, system and medium for a stone yard. Background Art

[0002] The existing supervision of stone transportation for transport vehicles in stone yards generally allows direct entry and exit. After confirmation by the weighbridge operator, the driver and the supervisor, the weight of the current transport vehicle can be determined and the vehicle can be released. In this method, when the vehicle driver enters the yard and passes through the weighbridge, the driver needs to get out of the vehicle and go to the weighbridge room to inform the weighbridge operator of the vehicle number, the transported materials, and whether it is a loaded vehicle or an empty vehicle. Then, the weighbridge operator reads the reading shown on the weighbridge display screen, issues a corresponding bill, and after the weighbridge operator, the driver, and the supervisor sign, the vehicle directly drives out of the yard. In this method, the proportion of manual participation is relatively high, and there is no need for safety inspection when the vehicle enters or exits, so it is impossible to effectively supervise the vehicles transporting stones. Especially, stones are goods that are extremely likely to generate dust and are likely to slide out of the carriage due to uneven ground and bumps. When transporting stones, measures such as tarpaulins are generally needed to cover and fix the stones to prevent them from falling. Therefore, it is necessary to check whether the transport vehicle is protected when the transport vehicle drives out of the yard.

[0003] Therefore, there is an urgent need for a method that can automatically supervise the release of transport vehicles in a stone yard. 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 yard. By calling the vehicle loading information and protection information of the vehicle to be released for safety inspection, when the vehicle loading information passes and the protection inspection passes, the exit electric rod is controlled to release the current vehicle to be released, realizing the automatic supervision of the vehicle.

[0005] To achieve the above purpose, the present application provides the following solutions:

[0006] On the one hand, the present invention provides a vehicle release control method for a stone yard, specifically including the following steps:

[0007] S1. Obtain the vehicle loading information of the current vehicle to be released, and obtain the body image of the vehicle to be released taken of the vehicle body;

[0008] S2. Use the vehicle loading information to check the vehicle information of the current vehicle to be released, and use the body image to check the protection of the current vehicle to be released. Among them, the method for checking the protection according to the body image is:

[0009] Obtain the empty vehicle image captured at the entrance corresponding to the vehicle to be released, input the vehicle body image and the empty vehicle image into the graphic recognition model, and perform vehicle body graphic annotation on the vehicle body image based on the empty vehicle image to obtain the image to be recognized with shape area annotation;

[0010] Compare the colors of each shape area in the image to be recognized. When the colors are the same, it is determined that the protection inspection passes; when the colors are different, the protection inspection fails;

[0011] S3. When both the vehicle information inspection and the protection inspection pass, control the exit electric rod to release the current vehicle to be released.

[0012] In some specific implementation schemes, in step S2, the vehicle body image includes the side image of the vehicle body, the shape area includes the rectangular carriage part and the special-shaped cargo part, and the specific process of comparing the colors of each shape area in the image to be recognized is as follows:

[0013] When the colors of the rectangular carriage part and the special-shaped cargo part are the same, it is determined that the protection inspection passes;

[0014] When the colors of the rectangular carriage part and the special-shaped cargo part are different, it is determined that the protection inspection fails.

[0015] In some specific implementation schemes, the vehicle body image includes the side image of the vehicle body and the top image of the vehicle body. The method for performing the protection inspection based on the vehicle body image is specifically as follows:

[0016] Input the side image of the vehicle body and the top image of the vehicle body into the graphic recognition model for graphic annotation respectively to obtain the side image to be recognized with shape area annotation and the top image to be recognized with shape area annotation;

[0017] When the shape area of the side image to be recognized only includes the rectangular carriage part, the shape area of the top image to be recognized includes the rectangular cargo part, compare whether the colors of the rectangular carriage part and the rectangular cargo part are the same. When the colors are the same, it is determined that the protection inspection passes.

[0018] In some specific implementation schemes, when the side image to be recognized includes the rectangular carriage part and the special-shaped cargo part, first compare whether the colors of the rectangular carriage part and the special-shaped cargo part are the same. If the colors of the rectangular carriage part and the special-shaped cargo part are the same, it is determined that the protection inspection passes when the colors are the same;

[0019] If the colors of the rectangular carriage part and the special-shaped cargo part are different, continue to judge whether the colors of the special-shaped cargo part and the rectangular cargo part are the same;

[0020] When the colors of the special-shaped cargo part and the rectangular cargo part are the same, it is determined that the protection inspection passes.

[0021] In some specific embodiments, when the colors of the rectangular carriage part and the rectangular cargo part are the same, the following steps are further included:

[0022] Extract the image of the rectangular cargo part from the top image to be recognized, and convert the image of the rectangular cargo part into a grayscale picture;

[0023] Divide the pixel points in the grayscale picture according to pixel coordinates by columns, each column being along the direction perpendicular to the vehicle head, to obtain multiple columns of continuous pixel data, and a column of pixel data is composed of pixel points with the same abscissa;

[0024] Obtain the grayscale values of all pixel points in the pixel data, calculate for each column of pixel data, calculate the average value of the grayscale values of the pixel points in the pixel data, and use this average value as the corresponding chromaticity value;

[0025] Determine whether the rectangular cargo part is completely covered according to the chromaticity values between adjacent two columns of pixel data in the grayscale picture.

[0026] In some specific embodiments, the process of determining whether the image of the rectangular cargo part is completely covered according to the chromaticity values between adjacent two columns of pixel data in the grayscale picture is as follows:

[0027] Obtain the chromaticity values of each column of pixel data in the grayscale picture, traverse the chromaticity values of each column of pixel data in the grayscale picture in a window moving traversal manner, set the length of the window to two, and the step value for each movement to one;

[0028] Compare whether the chromaticity values of adjacent two columns of pixel data within the window both belong to 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;

[0029] Move the window, obtain the chromaticity values of the next adjacent two columns of pixel point data for comparison until traversing all columns of pixel point data in the grayscale picture;

[0030] When the number of areas is greater than or equal to 2, determine that the rectangular cargo part is not completely covered.

[0031] In some specific embodiments, the vehicle cargo information includes obtaining the vehicle entrance detection information collected when vehicles with the same license plate information and close in time pass through the entrance weighbridge, and the vehicle exit detection information collected when the vehicles pass through the exit weighbridge; the vehicle entrance detection information includes the entry time, license plate information, empty vehicle weight, vehicle load, and the type of transported material, and the vehicle exit detection information includes the arrival time at the exit, license plate information, loaded weight, and the type of transported material.

[0032] In some specific embodiments, the specific process of vehicle information inspection is as follows:

[0033] Compare whether the type of material transported in the vehicle entry detection information is consistent with the type of material transported in the vehicle exit detection information. At the same time, judge whether the vehicle is overloaded by comparing the loaded weight with the vehicle load. If the types of materials transported are consistent and the vehicle is not overloaded, it is determined that the vehicle information inspection has passed.

[0034] In a second aspect, the present application provides a vehicle release control system for a stone yard, including:

[0035] An information acquisition module, configured to call the vehicle cargo information of the currently to-be-released vehicle from the vehicle information management center, and acquire a body image of the to-be-released vehicle taken by a monitoring device facing the vehicle;

[0036] A vehicle information inspection module, configured to perform vehicle information inspection on the currently to-be-released vehicle by using the vehicle cargo information;

[0037] A protection inspection module, configured to perform protection inspection on the currently to-be-released vehicle by using the body image;

[0038] The protection inspection is as follows: acquire an empty vehicle image taken at the entrance corresponding to the to-be-released vehicle, input the body image and the empty vehicle image into a graphic recognition model, perform body graphic annotation on the body image based on the empty vehicle image, and obtain an image to be recognized with shape area annotation;

[0043] The beneficial effects of the present invention are:

[0044] By carrying out safety supervision on the release of transport vehicles when they leave the stone yard, on the one hand, the cargo information of the currently to-be-released vehicle is inspected through the vehicle cargo information, and on the other hand, in order to prevent the transport vehicle from being released without safety protection measures such as covering the open top of the vehicle with a tarpaulin, the protection of the vehicle body is inspected. When both the vehicle information inspection and the protection inspection pass, the exit electric rod is controlled to release the currently to-be-released vehicle, which improves the safety of the vehicle transportation process and realizes the automatic supervision of the vehicle release in the stone yard.

[0055] Embodiment 1

[0056] As Figure 1As shown in the figure, this embodiment provides a vehicle release control method for a stone yard, which specifically includes the following steps:

[0057] S1. Obtain the vehicle loading information of the currently to-be-released vehicle, and obtain the body image of the to-be-released vehicle taken of its body.

[0058] It can be understood that when taking the body image of the to-be-released vehicle, it is obtained from the monitoring equipment that is directly to the right side of the to-be-released vehicle and can capture the top of the to-be-released vehicle.

[0059] S2. Use the vehicle loading information to check the vehicle information of the currently to-be-released vehicle, and use the body image to check the protection of the currently to-be-released vehicle. Among them,

[0060] The method for checking protection according to the body image is:

[0061] Obtain the empty vehicle image taken at the entrance corresponding to the to-be-released vehicle, input the body image and the empty vehicle image into the graphic recognition model, and perform body graphic annotation on the body image based on the empty vehicle image to obtain the to-be-recognized image with shape area annotation.

[0062] Compare the colors of each shape area in the to-be-recognized image. When the colors are the same, it is determined that the protection check passes; when the colors are different, the protection check fails.

[0063] Since the transport vehicles for transporting stones are generally self-unloading semi-trailers, the carriages of such trucks can be tilted to the side or backward for self-unloading. Generally, the top of the carriage is open to facilitate the rapid loading and unloading of stones. This will lead to the problem that when the stone loading and unloading is completed, it is easy for the stones to be higher than the carriage, and it is easy for the stones to fall due to bumps during vehicle transportation. At the same time, there is a large amount of dust in the untreated stones, and it is also easy to generate a large amount of dust during transportation, polluting the roadside environment. Currently, generally the most economical and practical method is to cover and fix the top of the carriage with a tarpaulin. The tarpaulin generally needs to cover at least the entire top of the carriage and be fixed on the frame of the carriage to cover the stones protruding from the carriage part. Commonly used is to cover the entire side and top of the carriage with a tarpaulin, which can protect the stones in the carriage and avoid the situation of falling or dust flying. Therefore, when the vehicle leaves the stone factory, it is necessary to check whether the carriage of the vehicle is effectively protected. Since the color of the tarpaulin is generally bright and different from the color of the carriage, and the stones are generally gray, it is very easy to identify whether the carriage is covered with a tarpaulin through color. Specifically, it includes the following situations:

[0064] When there is too much stone exceeding the carriage part of the vehicle body, it can be clearly seen in the image taken from the side of the vehicle that it is divided into the carriage part and the stone part. Through the trained image recognition model of the vehicle body, the image recognition model can identify the carriage part of the truck, so as to label the vehicle body part and the stone part in the vehicle body picture. For the side image of the vehicle body, the vehicle body part is generally rectangular, and the protruding part of the stone is generally irregular. It may be a pile of stones in the shape of multiple triangles, or it may be a pile of stones without a fixed shape. There is also a situation where the stones loaded on the vehicle do not exceed the carriage part of the vehicle body. Only the rectangular carriage part can be recognized in the image recognition model. At this time, it is necessary to combine the top image of the carriage taken to judge again whether the carriage is covered with a tarpaulin. Or, the image recognition model can be: the empty vehicle side picture taken from the side of the vehicle when the vehicle enters from the entrance is stored in the original dataset. 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. The monitoring position for taking the empty vehicle side picture of the vehicle corresponds to the shooting position for taking 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 directly opposite the side of the vehicle in the weighbridge room. By using the background subtraction method, the empty vehicle side picture and the side image of the vehicle body are compared, and the corresponding shape areas of the carriage part and the stone part can be marked in the side image of the vehicle body, which are the rectangular carriage part and the irregularly shaped cargo part respectively. This method can accurately obtain the area where the vehicle has changed and quickly identify the carriage and the stone part. Specifically:

[0065] 1. As Figures 3 - 4 shown, the vehicle body picture includes the side image of the vehicle body. When the image recognition model recognizes the side image of the vehicle body, the shape areas in the recognition result include the rectangular carriage part and the irregularly shaped cargo part. The colors of the rectangular carriage part and the irregularly shaped cargo part can distinguish whether the vehicle is covered. The specific process of comparing the colors of each shape area in the image to be recognized is as follows:

[0066] When the colors of the rectangular carriage part and the irregularly shaped cargo part are the same, it is judged that the protection inspection passes;

[0067] When the colors of the rectangular carriage part and the irregularly shaped cargo part are different, it is judged that the protection inspection fails.

[0068] 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 carriage part, the top image of the vehicle body is called, and the side image of the vehicle body and the top image of the vehicle are respectively input into the graphic recognition model for graphic annotation to obtain the side image to be recognized and the top image to be recognized with shape area annotation;

[0069] When the shape region of the side image to be recognized only includes the rectangular carriage part, the shape region of the top image to be recognized includes the rectangular cargo part. Compare whether the colors of the rectangular carriage part and the rectangular cargo part are the same. When the colors are the same, it is determined that the protection inspection passes.

[0070] 3. To avoid the situation where when the particle size of the stones in the stone material is relatively large, the tarpaulin is short and can only cover the top of the carriage and the stones protruding from the carriage, that is, when the side of the carriage is not covered. At this time, the side image of the vehicle body and the top image of the vehicle body are combined for judgment:

[0071] 3.1 When the side image to be recognized includes the rectangular carriage part and the irregular-shaped cargo part, first compare whether the colors of the rectangular carriage part and the irregular-shaped cargo part are the same. If the colors of the rectangular carriage part and the irregular-shaped cargo part are the same, it is determined that the protection inspection passes when the colors are the same;

[0072] 3.2 If the colors of the rectangular carriage part and the irregular-shaped cargo part are different, continue to judge whether the colors of the irregular-shaped cargo part and the rectangular cargo part are the same;

[0073] 3.3 When the colors of the irregular-shaped cargo part and the rectangular cargo part are the same, it is determined that the protection inspection passes.

[0074] It can be understood that the color judgment mentioned in this article can be RGB value discrimination or grayscale value discrimination. Since the colors of the tarpaulin, the carriage, and the stone material are relatively uniform and the color differences are relatively large. For example, 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 material is gray. Therefore, they can be distinguished by color. When comparing the colors of each shape region, generally, the average color value of the entire shape region is used as the color of the entire shape region. And in this application, the colors being the same means being the same within the allowable error range. Therefore, if there is an incomplete coverage, it is very easy to have a situation of missed judgment. Therefore, to avoid the situation of incomplete coverage, it also includes the steps:

[0075] 4.1 Cut out the rectangular cargo part image from the top image to be recognized, and convert the rectangular cargo part image into a grayscale picture;

[0076] According to the pixel coordinates, divide the pixel points in the grayscale picture into columns. Each column is along the direction perpendicular to the vehicle head, and multiple columns of continuous pixel data are obtained. A column of pixel data is composed of pixel points with the same abscissa. Taking the upper left corner of the grayscale picture as the origin, the direction parallel to the vehicle head is the abscissa, and the direction perpendicular to the vehicle head is the column;

[0077] 4.2 Obtain the grayscale values of all pixel points in the pixel data, calculate for each column of pixel data, calculate the average value of the grayscale values of the pixel points in the pixel data, and use this average value as the corresponding chromaticity value;

[0078] 4.3. Determine whether the rectangular cargo part is completely covered based on the chromaticity values between adjacent columns of pixel data in the grayscale image.

[0079] 4.3.1. Obtain the chromaticity values of each column of pixel data in the grayscale image. Traverse the chromaticity values of each column of pixel data in the grayscale image in a window moving traversal manner. Set the length of the window to two and the step value for each movement to one.

[0080] 4.3.2. Compare whether the chromaticity values of adjacent columns of pixel data within the window both belong to 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.

[0081] 4.3.3. Move the window to obtain the chromaticity values of the next adjacent two columns of pixel point data for comparison until all columns of pixel point data in the grayscale image are traversed.

[0082] 4.3.4 When the number of areas is greater than or equal to 2, determine that the rectangular cargo part is not completely covered.

[0083] Judging whether the carriage is completely covered is determined by the image of the rectangular cargo part of the vehicle top image. When there are multiple color partitions in the rectangular cargo part, it indicates that the carriage is not completely covered (in this article, it is considered that the tarpaulin is a solid-color tarpaulin).

[0084] S22. Use the vehicle cargo information to check the vehicle information of the current vehicle to be released. The specific process of vehicle information inspection is as follows:

[0085] To ensure that the types of goods transported and the vehicle load can pass the safety inspection throughout the process.

[0086] The vehicle cargo information includes obtaining the vehicle entrance detection information collected at the entrance weighbridge of vehicles with the same license plate information and close in time, and the vehicle exit detection information collected at the exit weighbridge of the vehicle. The vehicle entrance detection information includes the entry time, license plate information, empty vehicle weight, vehicle load, and type of transported materials. The vehicle exit detection information includes the arrival time at the exit, license plate information, loaded weight, and type of transported materials.

[0087] Compare whether the type of transported materials in the vehicle entrance detection information is consistent with the type of transported materials in the vehicle exit detection information. At the same time, judge whether the vehicle is overloaded by comparing the loaded weight with the vehicle load. If the type of transported materials is consistent and the vehicle is not overloaded, it is judged that the vehicle information inspection passes.

[0088] S3. When both the vehicle information inspection and the protection inspection pass, control the exit electric rod to release the current vehicle to be released.

[0089] As Figure 2 shown, in the scenario of the stone yard in this embodiment, the entrance and exit of the yard are separated, and the exit electric rod is controlled to release the vehicle. The entrance weighbridge device and the exit weighbridge device are respectively arranged on both sides of the weighbridge house, and the entrance weighbridge device and the exit weighbridge device are respectively arranged corresponding to the entrance direction and the exit direction. The computer in the weighbridge house is deployed with an information management system and a vehicle release control system, and the entrance weighbridge device, the exit weighbridge device, and each monitoring device in the stone yard are all connected to the information management system, and the information management system and the vehicle release control system are communicatively connected. Specifically, when a vehicle enters the stone yard from the yard entrance, the vehicle passes through the entrance weighbridge device. Both the entrance weighbridge device and the exit weighbridge device include a weighbridge, a monitoring device, and a display screen. The entrance weighbridge device can collect and record the entry time, license plate information, empty vehicle weight, vehicle load, and the type of transported material (the type of material can be actively informed by the driver or set according to the vehicle's historical loading material situation) of the transport vehicle and store them in the vehicle entry detection table. When the vehicle leaves the entrance weighbridge device, the driving track of the vehicle in the stone yard 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 device 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 stones, therefore, through the analysis of the monitoring video, the license plate number of the vehicle and the type of material in the stone material area where the vehicle reverses into are obtained, and the license plate number, material type, and loading time of the vehicle are returned to the management system and filled into the vehicle exit detection table. All fields in the vehicle exit detection table are used as a piece of data;

[0090] When the vehicle passes through the exit weighbridge device, the exit weighbridge device can collect and record the arrival time at the exit, license plate information, and loading weight of the transport vehicle, and find the corresponding data with the same license plate number in the vehicle exit detection table to complete the vehicle exit detection table. At the same time, according to the license plate information and the arrival time at the exit, the nearest entry detection information in the vehicle entry detection table is called, and first, whether the vehicle is overweight and whether the type of loaded material is consistent are checked. When the type of transported material is consistent and the vehicle is not overloaded, it is determined that the vehicle information inspection is passed and returned to the vehicle release control system. Then, the exit detection information and the entry detection information are merged to obtain the vehicle information, and the material load is calculated based on the empty vehicle mass and the loading weight, and the amount is calculated based on the material load and the material type. The generated amount can be returned to the vehicle release control system;

[0091] Then, the vehicle release control system reads the license plate information of the vehicle to be released. On the one hand, it reads the vehicle information inspection result from the information management system, then calls the monitoring equipment installed in the station that can capture the front, side, and top of the vehicle to obtain the body pictures, and conducts a protection inspection based on the body pictures. When the vehicle information inspection passes and the body protection inspection passes, additional criteria can be added. When the payment has been settled, the exit electric rod is controlled to release the current vehicle to be released.
