Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0051] In the description of this application, the terms "first," "second," etc. are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein. The objects distinguished by "first," "second," etc. are generally of the same type, and do not limit the number of objects. For example, the first object can be one or more.

[0052] Figure 1 is a schematic flow chart of the pavement defect repair method provided by the present application. The pavement defect repair method of the present application will be described below in conjunction with Figure 1. As shown in Figure 1, the method includes: Step 101, obtaining characteristic information of a target pavement defect and environmental data of the environment in which the target pavement defect resides. The characteristic information includes type, grade, and geometric information. The grade of the pavement defect is used to describe the severity of the pavement defect. The environmental data includes ambient temperature and humidity.

[0053] It should be noted that the executor of the embodiment of the present application is a pavement damage repair device.

[0054] Specifically, the target pavement defect is the target for repair in the pavement defect repair method provided herein. Based on the pavement defect repair method provided herein, a target dosage of a target repair material for repairing the target pavement defect can be determined. The target dosage of the target repair material can then be sprayed onto the target pavement defect, allowing pavement repair personnel or equipment to use the target dosage of the target repair material to repair the target defect.

[0055] It should be noted that the target pavement damage in the embodiment of the present application can be determined according to actual needs. The target pavement damage in the embodiment of the present application is not specifically limited.

[0056] Optionally, in the embodiment of the present application, the pavement defects in the road section to be repaired may be determined as target pavement defects.

[0057] It is understandable that the number of target pavement defects may be one or more.

[0058] In the embodiment of the present application, a temperature sensor may be used to obtain the ambient temperature of the environment where the target pavement defect is located; and a humidity sensor may be used to obtain the ambient humidity of the environment where the target pavement defect is located.

[0059] In the embodiments of the present application, characteristic information of the target pavement defect can be obtained in a variety of ways. For example, in the embodiments of the present application, characteristic information of the target pavement defect can be obtained based on user input; or, in the embodiments of the present application, characteristic information of the target pavement defect can be obtained based on deep learning technology. The specific method for obtaining characteristic information of the target pavement defect is not limited in the embodiments of the present application.

[0060] It should be noted that the types of pavement defects in the embodiments of the present application may include any number of pavement cracks, pavement block cracks, pavement longitudinal cracks, pavement transverse cracks, pavement settlement, pavement rutting, pavement wave bumps and pavement potholes.

[0061] In the embodiment of the present application, the geometric information of the pavement defect may include at least one of the lateral length, longitudinal length, depth, aspect ratio, density and area of ​​the pavement defect.

[0062] The level of pavement damage can be used to describe the severity of pavement damage.

[0063] Optionally, the pavement condition rating in the embodiments of the present application may be a Pavement Condition Index (PCI) rating. The PCI is a standardized indicator for evaluating and describing road pavement conditions, configured to measure pavement quality, damage, and maintenance requirements. The PCI is typically expressed on a scale of 0 to 100, with higher values ​​indicating better pavement conditions and lower values ​​indicating worse pavement conditions.

[0064] Optionally, in the embodiment of the present application, the levels of pavement defects can be divided into five levels, namely, excellent, good, medium, inferior and poor, in order of severity from low to high.

[0065] As an optional embodiment, obtaining characteristic information of target road surface damage includes: obtaining a road surface image of the road section to be repaired.

[0066] It should be noted that the road section to be repaired in the embodiment of the present application can be determined based on actual needs. The road section to be repaired in the embodiment of the present application is not specifically limited.

[0067] In the embodiment of the present application, a mobile three-dimensional image acquisition device can be used to obtain road surface images of the road section to be predicted.

[0068] Optionally, in embodiments of the present application, multiple mobile 3D image acquisition devices may be installed on a mobile object, with each of the mobile 3D image acquisition devices arranged perpendicular to the mobile object. While the multiple mobile objects are traveling in parallel along the road section to be repaired, the 3D image acquisition devices on each of the mobile objects can simultaneously capture images of the road surface of the road section to be repaired, thereby acquiring images of the road surface of the road section to be repaired as the road surface image of the road section to be repaired.

[0069] It should be noted that when the above-mentioned mobile body is traveling along the road section to be repaired, each of the above-mentioned mobile body three-dimensional image acquisition devices can simultaneously take pictures of the road surface of the road section to be repaired, which can reduce the distortion caused by camera distortion, thereby improving the image quality of the road surface image of the road section to be repaired.

[0070] Identify road surface defects on road images and obtain the type and geometric information of road surface defects in the road section to be repaired.

[0071] Specifically, after obtaining the road surface image of the road section to be repaired, the road surface disease identification of the road surface image of the road section to be repaired can be carried out through visual interpretation, deep learning technology, etc., to obtain the type and geometric information of the road surface disease in the road section to be repaired.

[0072] As an optional embodiment, road surface damage identification is performed on a road surface image to obtain the type and geometric information of the road surface damage in the road section to be repaired, including: inputting the road surface image into a road surface damage identification model, obtaining a road surface damage identification result of the road section to be repaired output by the road surface damage identification model, the road surface damage identification result including the location information, type, and geometric information of the road surface damage in the road section to be repaired;

[0073] The pavement defect recognition model is obtained after training based on sample pavement images of sample road sections and sample pavement defect recognition results of the sample pavement images; the sample pavement defect recognition results include the location information, type and geometric information of the pavement defects in the sample road sections.

[0074] Specifically, a mobile three-dimensional image acquisition device can be used to obtain sample road surface images of a sample road section.

[0075] It is understandable that there may be more than one sample road section. The more sample road sections there are, the higher the calculation accuracy of the trained road surface disease recognition model.

[0076] After obtaining the sample road surface images, the pavement defects in the sample road surface images can be identified through visual interpretation, and the geometric information, location information and type of the pavement defects in the sample road sections can be obtained.

[0077] After obtaining the geometric information, location information and type of pavement defects in the sample road section, the pavement defects and their location information, type and geometric information can be marked in the sample road image, and the marked sample road image can be determined as the sample pavement defect identification result of the sample road section.

[0078] After obtaining the sample road surface images of the sample road section and the sample road surface disease recognition results of the sample road section, the sample road surface images of the sample road section can be used as samples and the sample road surface disease recognition results of the sample road section can be used as sample labels to train the neural network model to obtain a road surface disease recognition model.

[0079] After obtaining the pavement damage recognition model, the pavement image of the road section to be repaired can be input into the pavement damage recognition model.

[0080] The pavement defect recognition model can identify pavement defects on the pavement image of the road section to be repaired, and obtain and output the pavement defect recognition results of the road section to be repaired.

[0081] It can be understood that the pavement disease identification results of the road section to be repaired in the embodiment of the present application may include the marked pavement image of the road section to be repaired, and the marked pavement image of the road section to be repaired is marked with pavement diseases and the type, location information and geometric information of the pavement diseases.

[0082] The pavement defects in the road section to be repaired are determined as target pavement defects, and the grade of the target pavement defects is obtained based on the type and geometric information of the target pavement defects.

[0083] Specifically, after obtaining the pavement disease identification results of the road section to be repaired, the pavement diseases in the road section to be repaired can be determined as target pavement diseases, and then based on the type and geometric information of the target pavement diseases, the level of the target pavement diseases can be obtained through conditional judgment, deep learning technology, etc.

[0084] For example: when the type of target pavement disease is pavement cracking, if the average crack width in the target pavement disease is determined to be 2mm based on the geometric information of the target pavement disease, the grade of the target pavement disease can be determined as good; if the average crack width in the target pavement disease is determined to be 5mm based on the geometric information of the target pavement disease, the grade of the target pavement disease can be determined as poor.

[0085] As an optional embodiment, obtaining a grade of a target pavement defect based on the type and geometric information of the target pavement defect includes: inputting the type and geometric information of the target pavement defect into a grading model, and obtaining the grade of the target pavement defect output by the grading model;

[0086] Among them, the classification model is obtained after training based on the type and geometric information of sample pavement diseases and the grade of sample pavement diseases.

[0087] Specifically, in the embodiment of the present application, the pavement defects in the sample road section can be determined as sample pavement defects, and then the type and geometric information of the sample pavement defects can be obtained based on the pavement defect identification results of the sample road section.

[0088] It can be understood that there are multiple sample pavement defects, and the number of sample pavement defects is positively correlated with the calculation accuracy of the classification model.

[0089] After obtaining the type and geometric information of the sample pavement disease, the level of the sample pavement disease can be determined based on the type and geometric information of the sample pavement disease and prior knowledge.

[0090] After obtaining the grade of the sample pavement disease, the neural network model can be trained using the type and geometric information of the sample pavement disease as samples and the grade of the sample pavement disease as sample labels to obtain a grading model.

[0091] After obtaining the classification model, the type and geometric information of the target pavement disease can be input into the classification model.

[0092] The grading model can be input into the grading model based on the type and geometric information of the target pavement disease, and the target pavement disease can be graded, and then the grade of the target pavement disease can be output.

[0093] The embodiment of the present application uses deep learning technology to identify pavement defects on pavement images of the road section to be repaired. After obtaining the pavement defect identification results of the road section to be repaired, the pavement defects in the road section to be repaired are determined as target pavement defects. Then, based on the type and geometric information of the target pavement defects, the level of the target pavement defects is obtained using deep learning technology. This can more accurately and efficiently obtain the characteristic information of the target pavement defects, reduce the cost of obtaining the characteristic information of the target pavement defects, and more efficiently achieve pavement defect repair of the road section to be repaired by determining the pavement defects in the road section to be repaired as target pavement defects.

[0094] Step 102: Based on the type of target pavement damage, determine the type of target repair material used to repair the target pavement damage, and based on the grade and geometric information of the target pavement damage, the type of target repair material, and environmental data, obtain the target dosage of the target repair material.

[0095] It should be noted that the types of repair materials in the embodiments of the present application may include but are not limited to emulsified asphalt, cement, concrete, and crushed stone mixtures.

[0096] It should be noted that, specifically, in the embodiments of the present application, a correspondence between different types of pavement damage and different types of repair materials can be established based on prior knowledge and / or actual conditions. For example, if the type of pavement damage is pavement cracking, the type of repair material corresponding to the pavement damage can be emulsified asphalt.

[0097] It should be noted that in the embodiment of the present application, the repair material used to repair the target pavement disease can be determined as the target repair material.

[0098] After obtaining the characteristic information of the target pavement defect, the type of target repair material can be determined based on the type of target pavement defect and the above-mentioned correspondence. For example, if the target pavement defect type is pavement cracking, the target repair material type can be emulsified asphalt.

[0099] After obtaining the type of target repair material, the amount of target repair material can be calculated through numerical calculation based on the grade and geometric information of the target pavement disease, the type of target repair material, and the environmental data of the environment where the target pavement disease is located.

[0100] As an optional embodiment, based on the grade and geometric information of the target pavement defect, the type of target repair material, and environmental data, obtaining a target amount of the target repair material includes: determining a value of a first coefficient based on the environmental data; determining a value of a second coefficient based on the type of target repair material and the grade of the target pavement defect according to a target mapping relationship; and calculating a repair area of ​​the target pavement defect based on the geometric information of the target pavement defect;

[0101] Among them, the target mapping relationship is used to describe the correspondence between different types and levels of pavement diseases and different values ​​of the second coefficient; the first coefficient is used to describe the depreciation of pavement repair materials under different environments; the second coefficient is used to describe the consumption of different types of pavement repair materials when repairing pavement diseases.

[0102] Specifically, based on the environmental data of the target pavement defect environment, the value of the first coefficient can be determined by conditional judgment. The first coefficient can be used to describe the loss of the repair material during the process of using the repair material to repair the pavement defect.

[0103] As an optional embodiment, determining a value of the first coefficient based on the environmental data includes: when the ambient temperature is higher than the first temperature or the ambient humidity is lower than the first humidity, taking the value of the first coefficient as the first value; when the ambient temperature is not higher than the first temperature and the ambient humidity is not lower than the first humidity, taking the value of the first coefficient as the second value;

[0104] Among them, the value range of the first temperature includes 4°C to 6°C; the value range of the first humidity includes 65% to 75%; the value range of the first value includes 1 to 1.1; the value range of the second value includes 1.05 to 1.15; the second value is greater than the first value.

[0105] It should be noted that low air humidity is beneficial to the fluidity and adhesion of pavement repair materials. Lower air humidity will reduce the moisture content in pavement repair materials, making it easier to control their fluidity and adhesion properties during construction.

[0106] It should be noted that when the ambient temperature is low, the fluidity and adhesion of the pavement repair material will be significantly affected, making it difficult to apply evenly on the pavement, affecting its adhesion performance to the pavement.

[0107] It is understandable that road asphalt construction requires a temperature of approximately 100°C or above, and the asphalt heating temperature in asphalt tankers is generally required to be around 130°C to facilitate unloading. During heating, the viscosity of the asphalt is particularly important.

[0108] Optionally, when the ambient temperature of the environment where the target pavement disease is located is higher than 5°C or the ambient humidity of the environment where the target pavement disease is located is lower than 70%, the value of the first coefficient can be 1.05; when the ambient temperature of the environment where the target pavement disease is located is not higher than 5°C and the ambient humidity of the environment where the target pavement disease is located is not lower than 70%, the value of the first coefficient can be 1.1.

[0109] It should be noted that in the embodiment of the present application, based on prior knowledge and / or actual conditions, a correspondence between different types of pavement diseases and different levels of pavement diseases and different values ​​of the second coefficient can be constructed as a target mapping relationship.

[0110] Optional, the target mapping relationship in the embodiment of the present application is shown in Table 1.

[0111] Table 1 Target mapping relationship table

[0112] Based on the geometric information of the target pavement damage, the repair area of ​​the target pavement damage can be calculated by numerical calculation.

[0113] The target dosage is calculated based on the value of the first coefficient, the value of the second coefficient and the repair area.

[0114] Specifically, after obtaining the value of the first coefficient, the value of the second coefficient, and the repair area of ​​the target road surface disease, the target amount of repair material can be calculated by numerical calculation as the target amount.

[0115] As an optional embodiment, the target usage is calculated based on the value of the first coefficient, the value of the second coefficient, and the repair area, including: calculating the product of the value of the first coefficient and the repair area as an intermediate result;

[0116] Calculate the quotient of the intermediate result and the value of the second coefficient as the target dosage.

[0117] Specifically, based on the values ​​of the first coefficient, the second coefficient, and the target repair area of ​​the pavement damage, the specific formula for calculating the target amount of the target repair material is as follows:

[0118] Where M represents the target amount of target repair material; k represents the first coefficient; A represents the repair area of ​​the target pavement disease, unit: m 2 ; P2 represents the second coefficient.

[0119] Step 103: Based on the target amount of the target repair material, control the repair material spraying equipment to spray the target amount of the target repair material at the target pavement defect to repair the target pavement defect.

[0120] Specifically, after obtaining the target dosage of the target repair material, the repair material spraying equipment can be controlled to spray the target dosage of the target repair material at the target pavement defect, so that the pavement defect repair personnel or pavement defect repair equipment can use the above target dosage of the target repair material to repair the target pavement defect.

[0121] After obtaining the target dosage of the target repair material, the above target dosage can also be sent to the terminal used by the pavement damage repair personnel, so that the pavement damage repair personnel can check the target dosage of the target repair material on the above terminal, and then spray the target dosage of the target repair material at the target pavement damage, and then use the above target dosage of the target repair material to repair the target pavement damage.

[0122] The embodiment of the present application determines the type of target repair material for repairing the target pavement disease based on the type of the target pavement disease, obtains the target amount of the target repair material based on the grade, geometric information, type of the target repair material and environmental data of the environment where the target pavement disease is located, and then controls the repair material spraying equipment to spray the target amount of the target repair material at the target pavement disease based on the above target amount to repair the target pavement disease. The amount of repair material for repairing the pavement disease can be determined more objectively and accurately, and the problem of excessive or insufficient amount of repair material causing waste of repair costs or poor repair effects can be avoided. The process of determining the amount of repair material is simple, efficient and real-time, which can improve the efficiency and effect of pavement disease repair and improve road driving safety and comfort.
