[0001] This application relates to the technical field of road construction, and more specifically, to a method and system for evaluating the construction quality of asphalt pavement. Background Technology

[0002] Asphalt pavement is a flexible pavement, and its surface is very smooth after paving. It also has a certain noise reduction effect, resulting in less bumps and lower noise when vehicles are driving, which can greatly improve the comfort of driving. Therefore, asphalt pavement has been more widely used.

[0003] Currently, during asphalt pavement construction, the method of manual recording by the supervisor is usually adopted to observe whether the roller has compacted to the designated position each time. However, in the high-temperature and smoky environment, visual fatigue after long-term operation makes it difficult to see the specific edges, resulting in low reliability, which needs further improvement.

[0017] To illustrate the technical solution described in this application, specific embodiments are provided below.

[0018] Please see Figure 1 , Figure 1 This is a flowchart illustrating the construction quality evaluation method based on asphalt pavement provided in this embodiment. In this embodiment, the execution subject of the construction quality evaluation method is a terminal device. It is understood that the types of terminal devices include, but are not limited to, tablet computers, laptops, Ultra-Mobile Personal Computers (UMPCs), netbooks, Personal Digital Assistants (PDAs), etc. This embodiment does not impose any restrictions on the specific type of terminal device.

[0019] Please see Figure 1The construction quality evaluation method provided in this application includes, but is not limited to, the following steps: In S100, multiple real-time construction image information are acquired based on a preset camera and a preset shooting interval value.

[0020] Specifically, the terminal device can first use a preset camera to intermittently take pictures of the asphalt pavement according to a preset shooting interval value. After each shooting interval value, the camera will take pictures sequentially to obtain multiple real-time construction image information. The real-time construction image information is used to describe the images obtained by the camera from the asphalt pavement. The camera can be pre-fixed and installed on the street lamps around the construction pavement so that the camera's shooting range can cover the asphalt pavement to be constructed.

[0021] In S200, for each real-time construction image, based on a preset target detection algorithm, the target roller location information and the corresponding edge contour information are determined.

[0022] Specifically, after the terminal device acquires multiple real-time construction image information, the terminal device can perform this processing on each real-time construction image information. Based on a preset target detection algorithm, the target road roller is detected and processed to determine the target road roller's position information and the corresponding edge contour information. The target detection algorithm can be Fast R-CNN, Libra R-CNN, or YOLOv10. The target road roller's position information is used to describe the position of the target road roller on the asphalt pavement, and the edge contour information is used to describe the edge contour corresponding to the contact edge between the target road roller and the asphalt pavement.

[0023] In S300, construction quality evaluation information is generated based on the target roller's location information and edge contour information.

[0024] Specifically, after the terminal equipment determines the location information and edge contour information of the target roller, it can effectively generate construction quality evaluation information based on the location information and edge contour information of the target roller. The construction quality evaluation information is used to evaluate the construction quality of asphalt pavement.

[0025] In some possible implementations, for the effective generation of construction quality evaluation information, please refer to [link / reference]. Figure 2 Step S300 includes, but is not limited to, the following steps: In S310, the system continuously executes responses to received stage completion instructions, determining coverage information based on the edge contour information corresponding to the first and last target roller positions, until the final compaction completion instruction is received.

[0026] Specifically, the terminal device can repeatedly execute the response to the received stage completion command, and effectively determine the coverage information based on the edge contour information corresponding to the first target roller location information and the edge contour information corresponding to the last target roller location information, until the final compaction completion command is received.

[0027] In some possible implementations, for effectively determining coverage information, please refer to [link / reference]. Figure 2 Step S310 includes, but is not limited to, the following steps: In S311, in response to the received stage completion command, the first wheel-side endpoint information is determined based on the edge contour information corresponding to the first target roller position information, and the second wheel-side endpoint information is determined based on the edge contour information corresponding to the last target roller position information.

[0028] Specifically, in response to the received stage completion command, the terminal device can determine the first wheel-side endpoint information based on the edge contour information corresponding to the initial target roller position information, and determine the second wheel-side endpoint information based on the edge contour information corresponding to the final target roller position information. The stage completion command is used to instruct the target roller to complete a single rolling task, such as moving from the right side of the asphalt pavement to the left side of the asphalt pavement. The first wheel-side endpoint information is used to describe the corner points in the edge contour information corresponding to the initial target roller position information, and the second wheel-side endpoint information is used to describe the corner points in the edge contour information corresponding to the final target roller position information.

[0029] In S312, wheel side connection information is generated based on the information of the first wheel side endpoints and the second wheel side endpoints that are furthest apart.

[0030] Specifically, after the terminal device determines the first wheel-side endpoint information and the second wheel-side endpoint information, the terminal device can generate wheel-side connection information based on the first wheel-side endpoint information and the second wheel-side endpoint information that are furthest apart. The wheel-side connection information is used to describe the connection formed by connecting the first wheel-side endpoint information and the second wheel-side endpoint information that are furthest apart.

[0031] In S313, obtain the roller width information of the target road roller.

[0032] Specifically, after the terminal device generates the wheel side connection information, the terminal device can obtain the roller width information of the target road roller, wherein the roller width information is used to describe the width of the roller of the target road roller.

[0033] In S314, the coverage information is determined based on the roller width information and the wheel side connection information.

[0034] Specifically, after the terminal device obtains the roller width information, it can effectively determine the coverage area information based on the closed pattern formed by the roller width information and the wheel side connection information.

[0035] In S315, the process cyclically executes in response to the received stage completion command. Based on the edge contour information corresponding to the initial target roller position information, the first wheel side endpoint information is determined, and based on the edge contour information corresponding to the final target roller position information, the second wheel side endpoint information is determined. Then, based on the roller width information and the wheel side connection information, the coverage information is determined until the final compaction completion command is received.

[0036] Specifically, after the terminal device determines the coverage information, the terminal device can repeatedly execute the above steps S311 to S314 until it receives the final compaction completion instruction. The final compaction completion instruction is used to instruct the target roller to complete multiple compaction tasks on the asphalt pavement.

[0037] In S320, overlapping range information is determined sequentially based on any two consecutive coverage range information.

[0038] Specifically, after the terminal device determines the coverage information, the terminal device can effectively determine the overlapping range information based on any two consecutive coverage information. The overlapping range information is used to describe the overlapping range between any two consecutive coverage information.

[0039] In S330, the overlapping area information is generated based on the overlapping area information.

[0040] Specifically, after the terminal device determines the overlapping range information, the terminal device can use the Monte Carlo method and the Gaussian area formula to calculate the area of ​​the overlapping range information, effectively generating the overlapping range area information, which is used to describe the area of ​​the overlapping range information.

[0041] In S340, construction quality evaluation information is generated based on the overlapping area information and the preset overlapping area threshold.

[0042] Specifically, after the terminal device generates the overlapping area information, it can accurately generate construction quality evaluation information based on the overlapping area information and the preset overlapping area threshold. The construction quality evaluation information includes quality qualified information or quality abnormal information. Quality qualified information is used to describe that the construction quality of the asphalt pavement is qualified; quality abnormal information is used to describe that the construction quality of the asphalt pavement is unqualified.

[0043] In some possible implementations, to achieve accurate generation of construction quality evaluation information, please refer to [link / reference]. Figure 4 Prior to step S340, the method further includes, but is not limited to, the following steps: In S3401, the preset road length information is obtained.

[0044] Specifically, the terminal device can obtain preset road length information, which is used to describe the length of the asphalt pavement.

[0045] In S3402, an overlap area threshold is generated based on the road length information and the preset qualified overlap distance value.

[0046] Specifically, after the road length information is obtained from the terminal device, the terminal device can generate an overlap area threshold based on the product of the road length information and the preset qualified overlap distance value information. The qualified overlap distance value information is a preset value, such as 10 centimeters or 20 centimeters.

[0047] Accordingly, please refer to Figure 5 Step S340 includes, but is not limited to, the following steps: In S341, the overlapping area information is compared with the preset overlapping area threshold.

[0048] Specifically, after the terminal device generates the overlapping area threshold, the terminal device can compare the overlapping area information with the preset overlapping area threshold.

[0049] In S342, if the overlapping area information is less than the overlapping area threshold, the construction quality evaluation information is determined to be quality abnormal information.

[0050] Specifically, if the overlapping area information is less than the overlapping area threshold, it indicates that the overlapping area of ​​the compaction wheel tracks has not met the requirements, so the terminal equipment can determine that the construction quality evaluation information is abnormal.

[0051] In S343, if the overlapping area information is greater than or equal to the overlapping area threshold, the construction quality evaluation information is determined to be qualified.

[0052] Specifically, if the overlapping area information is greater than or equal to the overlapping area threshold, it indicates that the overlapping area of ​​the compaction wheel tracks meets the requirements, and the terminal equipment can determine that the construction quality evaluation information is qualified.

[0053] In some possible implementations, to improve the construction quality of asphalt pavements and reduce areas of pressure leakage, please refer to [the relevant documentation / reference]. Figure 6 If the construction quality evaluation information is abnormal, then after step S300, the method further includes, but is not limited to, the following steps: In S400, the target overpressure area information is determined based on the overlapping area information that is less than the overlapping area threshold.

[0054] Specifically, the terminal device can effectively determine the target re-compacting area information based on the overlapping area information corresponding to the overlapping area information that is less than the overlapping area threshold. The target re-compacting area information is used to describe the area that needs to be compacted again by the target roller.

[0055] In S410, target compression area information is sent to the designated terminal.

[0056] Specifically, after the terminal device determines the target repressurization area information, the terminal device can send the target repressurization area information to the designated terminal of the operator or commander.

[0057] The implementation principle of the construction quality evaluation method for asphalt pavement in this application embodiment is as follows: The terminal device can first acquire multiple real-time construction image information based on a preset camera and a preset shooting interval value. Then, for each real-time construction image information, based on a preset target detection algorithm, the target roller position information and the corresponding edge contour information are effectively determined. Finally, based on the target roller position information and the edge contour information, construction quality evaluation information is accurately generated, thereby automatically judging whether there is a compliant overlapping area between the compaction ranges corresponding to two adjacent rolling operations, reducing the link of manual visual judgment and improving reliability.
