Description

Technical Field

[0001] This invention relates to the field of data processing technology, and in particular to a method, device, equipment, and storage medium for monitoring violations during bridge construction. Background Technology

[0002] Bridges, as vital transportation links between two places, hold significant strategic importance. Bridge construction is challenging, involving numerous complex stages. Furthermore, monitoring violations during bridge construction plays a crucial role in ensuring bridge quality, guaranteeing construction safety, controlling construction progress, and improving efficiency; therefore, it has become an indispensable safety measure in bridge construction.

[0003] Traditional manual monitoring of bridge construction violations suffers from low efficiency, high subjectivity, and significant challenges in monitoring multiple stages and steps, resulting in low accuracy. With the maturity and application of drone technology, the introduction of drones for monitoring violations in bridge construction has become a popular trend. Drones offer more efficient and accurate monitoring of violations, avoiding the influence of subjective human judgment. However, existing drones for monitoring violations still have some limitations in certain bridge construction monitoring scenarios:

[0004] (1) Differences in monitoring distance for violations: Considering the complexity of bridge construction, which usually involves multiple construction steps in multiple stages, and the different construction scenarios and requirements of different bridges, there are different monitoring distance standards for violations in many stages and construction steps (for example, in the superstructure construction stage, for the joint between precast beams and cast-in-place beams, the image acquisition for checking the setting of connecting steel bars and the quality of concrete pouring requires close-range image acquisition within 20 meters; in the substructure construction stage, for the construction of bridge piers and abutments, the image acquisition for checking whether the spacing, quantity, and binding firmness of steel bars meet the design requirements requires medium-range image acquisition of 20 to 50 meters; and for monitoring the location and status of large equipment, the image acquisition requires long-range image acquisition of more than 50 meters). Different monitoring distance standards for violations increase the difficulty for UAVs in performing flight planning and image acquisition in the construction area. (2) There are differences in the frequency of violation monitoring: Considering that in the scenario of progressive bridge construction, different construction procedures may be carried out in each bridge construction section at the same time, the violation monitoring drone needs to deal with the monitoring needs of different construction procedures and different construction scenarios at the same time. Different construction procedures under different construction scenarios usually have different violation monitoring frequency standards (for example, the concrete pouring process of large-volume bridge piers requires image acquisition every hour or even shorter time intervals to ensure timely detection of violations such as segregation and insufficient compaction in the concrete layer pouring process; the sealing degree and usage status of drainage pipes during construction require image acquisition every 3-6 hours; and the cracks, peeling, and rust on the surface of bridge piers and beams require image acquisition every 3-5 days). Different violation monitoring frequency standards further increase the difficulty of drones in performing flight planning and image acquisition in the construction area. (3) Violation monitoring drones have limited endurance in actual application. In order to improve the monitoring capability of violation monitoring drones, it is necessary to optimize the flight path of violation monitoring drones when performing flight planning and image acquisition as much as possible.

[0005] Therefore, how to provide flight planning and image acquisition control schemes for violation monitoring drones that are adapted to different violation monitoring distances and frequencies for several construction steps in the numerous stages of bridge construction, while improving the accuracy and efficiency of violation monitoring in bridge construction and extending the monitoring time of violation monitoring drones during flight planning and image acquisition as much as possible, is a technical problem that urgently needs to be solved. Summary of the Invention

[0006] This invention provides a method, apparatus, equipment, and storage medium for monitoring violations during bridge construction, aiming to solve at least one of the aforementioned technical problems.

[0007] To achieve the above objectives, the present invention provides a method for monitoring violations during bridge construction, comprising the following steps:

[0008] Obtain bridge construction plan information; wherein, the bridge construction plan information includes several bridge construction sections in the target bridge, several construction procedures in each bridge construction section, and the planned time period for each bridge construction section to perform each construction procedure;

[0009] Based on the several construction procedures of each bridge construction section and the planned time period for each construction procedure in each bridge construction section, determine several construction monitoring points for the target bridge and the effective monitoring period for each of the construction monitoring points.

[0010] Obtain pre-defined bridge construction monitoring requirements, extract monitoring type information and monitoring risk level of each construction monitoring point in the bridge construction monitoring requirements, consider the effective monitoring time period of each construction monitoring point, take the image acquisition distance interval corresponding to the monitoring type information and the image acquisition frequency interval corresponding to the monitoring risk level as constraints, take the minimum flight distance as the optimization objective, and optimize the UAV image acquisition path planning strategy for the target construction bridge.

[0011] Based on the UAV image acquisition path planning strategy, UAV flight and image acquisition control commands are generated to drive the violation monitoring UAV to perform corresponding flight and image acquisition actions, and to judge the violation of bridge construction based on the acquired bridge construction images.

[0012] After the violation monitoring drone completes each flight and image acquisition action, it obtains the bridge construction progress, updates the bridge construction plan information based on the bridge construction progress, and regenerates the drone image acquisition path planning strategy using the updated bridge construction plan information.

[0013] Optionally, the steps for obtaining bridge construction plan information include:

[0014] Obtain historical bridge construction progress information for the main bridge construction project; extract the historical time consumption of each construction procedure for different reference bridge construction sections from the historical bridge construction progress information; obtain the target bridge construction task; and extract several bridge construction sections and several construction procedures for each bridge construction section from the target bridge construction task.

[0015] Based on the similarity matching of the construction content characteristics of each bridge construction section in the reference bridge construction section and the target bridge construction section, several reference bridge construction sections with a construction content characteristic similarity higher than the target value are matched for each bridge construction section.

[0016] Based on the historical time consumption of each construction procedure in several reference bridge construction sections with matching relationships for each bridge construction section, the planned time consumption of each construction procedure in each bridge construction section is calculated by averaging the historical time consumption.

[0017] Based on the planned time consumption of each construction procedure in each bridge construction section, the planned time period for each construction procedure in each bridge construction section of the target bridge is determined, and bridge construction plan information is generated using the planned time period of each construction procedure.

[0018] Optionally, based on several construction procedures in each bridge construction section and the planned time period for each construction procedure in each bridge construction section, the steps for determining several construction monitoring points for the target bridge and the effective monitoring time period for each construction monitoring point are as follows:

[0019] By utilizing several construction procedures in each bridge construction section, the construction monitoring items for each construction procedure are matched in a pre-defined list of bridge construction monitoring items. By calling the target construction bridge drawings, the construction monitoring location of each construction monitoring item is queried, and several construction monitoring points are obtained.

[0020] Based on the planned time period for each construction procedure in each bridge construction section, the effective monitoring period for each construction monitoring point under each construction procedure is determined.

[0021] Optionally, the following steps are taken to optimize the UAV image acquisition path planning strategy for the target construction bridge: First, obtain pre-defined bridge construction monitoring requirements. Second, extract monitoring type information and monitoring risk level for each construction monitoring point from the pre-defined requirements. Third, consider the effective monitoring time period for each monitoring point. Fourth, use the image acquisition distance interval corresponding to the monitoring type information and the image acquisition frequency interval corresponding to the monitoring risk level as constraints. Fifth, use the minimum flight distance as the optimization objective.

[0022] Obtain pre-defined bridge construction monitoring requirements, and extract monitoring type information and monitoring risk level for each construction monitoring point in the bridge construction monitoring requirements; wherein, the monitoring type includes several monitoring types of construction violations corresponding to several different image acquisition distance intervals, and the monitoring risk level includes several monitoring risk levels of construction violations corresponding to several different image acquisition frequency intervals;

[0023] Using the monitoring type information and monitoring risk level, the image acquisition distance and image acquisition frequency of each construction monitoring point are matched in the first mapping table of preset monitoring type and image acquisition distance range and the second mapping table of preset monitoring risk level and image acquisition frequency range, respectively.

[0024] Considering the effective monitoring period of each construction monitoring point, and taking the image acquisition distance range and the image acquisition frequency range as constraints, with the minimum flight distance as the optimization objective, the UAV image acquisition path planning strategy for the target construction bridge is optimized and solved.

[0025] Optionally, considering the effective monitoring period for each construction monitoring point, and using the image acquisition distance range and the image acquisition frequency range as constraints, with the minimum flight distance as the optimization objective, the optimization steps for solving the UAV image acquisition path planning strategy for the target construction bridge are specifically included:

[0026] Construct a three-dimensional model map of the target construction bridge, and generate the effective monitoring area of ​​each construction monitoring point in the three-dimensional model map based on the image acquisition distance range of each construction monitoring point;

[0027] To obtain the flight speed range of the violation monitoring drone, considering the effective monitoring period and effective monitoring area of ​​each construction monitoring point, several drone acquisition points are selected within the effective monitoring period and effective monitoring area. The first constraint is that the actual flight speed determined by the image acquisition interval time and image acquisition position of two adjacent drone acquisition points within each generated drone image acquisition path falls within the flight speed range. The second constraint is that the image acquisition interval time of two adjacent drone acquisition points of each construction monitoring point satisfies the image acquisition frequency range within the generated drone image acquisition paths. The optimization objective is to minimize the cumulative flight distance of the violation monitoring drone in the generated drone image acquisition paths, thereby optimizing the solution for the image acquisition time and image acquisition position of each drone acquisition point in the several drone image acquisition paths.

[0028] Based on the image acquisition time and location of each drone acquisition point in several drone image acquisition paths, a drone image acquisition path planning strategy is generated for the target construction bridge.

[0029] Optionally, based on the UAV image acquisition path planning strategy, UAV flight and image acquisition control commands are generated to drive the violation monitoring UAV to perform corresponding flight and image acquisition actions, and bridge construction violation judgment steps are performed based on the acquired bridge construction images, specifically including:

[0030] Extract the image acquisition time and image acquisition position of each UAV acquisition point in each UAV image acquisition path in the UAV image acquisition path planning strategy, and calculate the flight speed between two adjacent UAV acquisition points in each UAV image acquisition path;

[0031] Based on the image acquisition location of each UAV acquisition point and the flight speed between two adjacent UAV acquisition points, UAV flight control commands are generated. Based on the image acquisition time of each UAV acquisition point, UAV image acquisition commands are generated, thus obtaining UAV flight and image acquisition control commands.

[0032] The flight and image acquisition control commands of the UAV are sent to the violation monitoring UAV, which instructs the violation monitoring UAV to perform corresponding flight and image acquisition actions, and judges the violation of bridge construction based on the acquired bridge construction images.

[0033] Optionally, after the violation monitoring drone completes each flight and image acquisition action, the bridge construction progress is obtained, the bridge construction plan information is updated based on the bridge construction progress, and the drone image acquisition path planning strategy is regenerated using the updated bridge construction plan information. Specifically, this includes:

[0034] After the drone monitoring violations completes each flight and image acquisition action, it obtains the bridge construction progress of the target bridge and extracts the actual time period during which the construction process is currently being carried out in each bridge construction section of the bridge construction progress.

[0035] Based on the planned time period for each construction procedure in each bridge construction section in the bridge construction plan information and the actual time period for each construction procedure currently being performed in each bridge construction section in the bridge construction progress, it is determined whether the time overlap ratio between the actual time period and the planned time period for the corresponding construction procedure is lower than the preset target ratio. If so, the construction procedure corresponding to the actual time period is defined as an error procedure.

[0036] Determine whether the number of error-prone construction procedures currently being performed in each bridge construction section exceeds the preset target number. If so, update the bridge construction plan information based on the bridge construction progress, and regenerate the UAV image acquisition path planning strategy using the updated bridge construction plan information.

[0037] Furthermore, to achieve the above objectives, the present invention also provides a bridge construction violation monitoring device, comprising:

[0038] The acquisition module is used to acquire bridge construction plan information; wherein, the bridge construction plan information includes several bridge construction sections in the target bridge, several construction procedures in each bridge construction section, and the planned time period for each bridge construction section to perform each construction procedure.

[0039] The determination module is used to determine several construction monitoring points of the target bridge and the effective monitoring period of each construction monitoring point based on several construction procedures of each bridge construction section and the planned time period for each construction procedure of each bridge construction section.

[0040] The solution module is used to obtain the pre-defined bridge construction monitoring requirements, extract the monitoring type information and monitoring risk level of each construction monitoring point in the bridge construction monitoring requirements, consider the effective monitoring time period of each construction monitoring point, take the image acquisition distance interval corresponding to the monitoring type information and the image acquisition frequency interval corresponding to the monitoring risk level as constraints, and take the minimum flight distance as the optimization objective to optimize and solve the UAV image acquisition path planning strategy for the target construction bridge.

[0041] The execution module is used to generate UAV flight and image acquisition control commands based on the UAV image acquisition path planning strategy, drive the violation monitoring UAV to perform corresponding flight and image acquisition actions, and perform bridge construction violation judgment based on the acquired bridge construction images.

[0042] The update module is used to obtain the bridge construction progress after the violation monitoring drone completes each flight and image acquisition action, update the bridge construction plan information based on the bridge construction progress, and regenerate the drone image acquisition path planning strategy using the updated bridge construction plan information.

[0043] In addition, to achieve the above objectives, the present invention also provides a bridge construction violation monitoring device, which includes: a memory, a processor, and a bridge construction violation monitoring program stored in the memory and executable on the processor. When the bridge construction violation monitoring program is executed by the processor, it implements the steps of the bridge construction violation monitoring method described above.

[0044] In addition, to achieve the above objectives, the present invention also provides a storage medium storing a bridge construction violation monitoring program, which, when executed by a processor, implements the steps of the bridge construction violation monitoring method described above.

[0045] The beneficial effects of this invention are as follows: It proposes a method, device, equipment, and storage medium for monitoring violations during bridge construction. By acquiring bridge construction plan information and utilizing the planned time periods for each construction process in each bridge construction section, the effective monitoring time period for each construction monitoring point is determined. Based on the pre-defined bridge construction monitoring requirements, the monitoring type information and monitoring risk level of each construction monitoring point are considered. The image acquisition distance range corresponding to the monitoring type information and the image acquisition frequency range corresponding to the monitoring risk level are used as constraints, and the flight distance is used as the optimization objective to optimize the UAV image acquisition path planning strategy for the target bridge construction. This strategy controls the UAV to execute flight, image acquisition, and bridge construction violation judgment. Therefore, this invention proposes a construction image acquisition scheme that adapts to the different monitoring distances and frequencies of different construction stages during bridge construction. While improving the accuracy and efficiency of monitoring violations, it extends the monitoring time of the UAV for violation monitoring as much as possible, exhibiting good scenario adaptability.

[0060] After the violation monitoring drone completes each flight and image acquisition action, it obtains the bridge construction progress, updates the bridge construction plan information based on the bridge construction progress, and regenerates the drone image acquisition path planning strategy using the updated bridge construction plan information.

[0061] The specific embodiments of the present invention applied to the device are basically the same as the embodiments of the bridge construction violation monitoring method described below, and will not be repeated here.

[0062] This invention provides a method for monitoring violations during bridge construction, referring to... Figure 2 , Figure 2 This is a flowchart illustrating an embodiment of the bridge construction violation monitoring method of the present invention.

[0063] In this embodiment, the method for monitoring bridge construction violations includes the following steps:

[0064] S100: Obtain bridge construction plan information; wherein, the bridge construction plan information includes several bridge construction sections in the target bridge, several construction procedures in each bridge construction section, and the planned time period for each bridge construction section to perform each construction procedure.

[0065] S200: Based on several construction procedures in each bridge construction section and the planned time period for each construction procedure in each bridge construction section, determine several construction monitoring points for the target bridge and the effective monitoring period for each construction monitoring point.

[0066] S300: Obtain the pre-defined bridge construction monitoring requirements, extract the monitoring type information and monitoring risk level of each construction monitoring point in the bridge construction monitoring requirements, consider the effective monitoring time period of each construction monitoring point, take the image acquisition distance interval corresponding to the monitoring type information and the image acquisition frequency interval corresponding to the monitoring risk level as constraints, take the minimum flight distance as the optimization objective, and optimize the solution of the UAV image acquisition path planning strategy for the target construction bridge.

[0067] S400: Based on the UAV image acquisition path planning strategy, generate UAV flight and image acquisition control commands to drive the violation monitoring UAV to perform corresponding flight and image acquisition actions, and perform bridge construction violation judgment based on the acquired bridge construction images.

[0068] S500: After the violation monitoring drone completes each flight and image acquisition action, it obtains the bridge construction progress, updates the bridge construction plan information based on the bridge construction progress, and regenerates the drone image acquisition path planning strategy using the updated bridge construction plan information.

[0069] It should be noted that existing illegal behavior monitoring drones still have some limitations in bridge construction monitoring in some scenarios: (1) There are differences in the illegal behavior monitoring distance: Considering the complexity of bridge construction, which usually includes multiple construction steps in multiple stages, and the different construction scenarios and needs of different bridges, there are different illegal behavior monitoring distance standards for many stages and construction steps. Different illegal behavior monitoring distance standards increase the difficulty for drones to perform flight planning and image acquisition in the construction area. (2) There are differences in the illegal behavior monitoring frequency: Considering that in the scenario of progressive bridge construction, since each bridge construction section may perform different construction procedures at the same time, illegal behavior monitoring drones need to simultaneously cope with the monitoring needs of different construction procedures and construction scenarios. Different construction procedures in different construction scenarios usually have different illegal behavior monitoring frequency standards. Different illegal behavior monitoring frequency standards further increase the difficulty for drones to perform flight planning and image acquisition in the construction area. (3) Illegal behavior monitoring drones have limited endurance in actual applications. In order to improve the monitoring capabilities of illegal behavior monitoring drones, it is necessary to optimize the flight path of illegal behavior monitoring drones when performing flight planning and image acquisition as much as possible.

[0070] To address the aforementioned issues, this embodiment obtains bridge construction plan information and utilizes the planned time periods for each construction procedure in each bridge construction section to determine the effective monitoring time period for each construction monitoring point. Based on the pre-defined bridge construction monitoring requirements, it optimizes the image acquisition path planning strategy for the target bridge construction using the image acquisition distance range corresponding to the monitoring type information and the image acquisition frequency range corresponding to the monitoring risk level as constraints, and the flight distance as the optimization objective. This strategy controls the drone's flight, image acquisition, and bridge construction violation judgment. Therefore, this invention proposes a construction image acquisition scheme adapted to the different monitoring distances and frequencies required in different construction stages of bridge construction. This improves the accuracy and efficiency of monitoring bridge construction violations while maximizing the monitoring time of the drone, demonstrating good scenario adaptability.

[0071] In a preferred embodiment, the step of obtaining bridge construction plan information specifically includes:

[0072] S110: Obtain historical bridge construction progress information of the main bridge construction entity, extract the historical time consumption of each construction procedure in different reference bridge construction sections from the historical bridge construction progress information, obtain the target bridge construction task, and extract several bridge construction sections and several construction procedures of each bridge construction section from the target bridge construction task.

[0073] S120: Based on the similarity matching of the construction content characteristics of the reference bridge construction section and each bridge construction section in the target bridge, match several reference bridge construction sections whose construction content characteristics are more similar than the target value for each bridge construction section.

[0074] S130: Based on the historical time consumption of each construction procedure in several reference bridge construction sections with matching relationships for each bridge construction section, calculate the planned time consumption of each construction procedure in each bridge construction section by averaging the historical time consumption.

[0075] S140: Based on the planned time consumption of each construction procedure in each bridge construction section, determine the planned time period for each construction procedure in each bridge construction section of the target bridge, and generate bridge construction plan information using the planned time period of each construction procedure.

[0076] In this embodiment, by acquiring the historical bridge construction progress information of the main bridge construction entity, and based on the historical time consumption of each construction procedure in different reference bridge construction sections, the main bridge construction entity first uses the method of construction content feature similarity matching to match several corresponding reference bridge construction sections for each bridge construction section. Then, the average value of the historical time consumption of each construction procedure in several reference bridge construction sections is calculated, which is used as the planned time consumption of each construction procedure in each bridge construction section. Finally, based on the planned time consumption of each construction procedure, the planned time period of each construction procedure is determined according to the execution order of the bridge construction section and the construction procedure, thereby generating the final bridge construction plan information.

[0077] In a preferred embodiment, the steps of determining several construction monitoring points for the target bridge and the effective monitoring period for each construction monitoring point, based on several construction procedures for each bridge construction section and the planned time period for each construction procedure in each bridge construction section, specifically include:

[0078] S210: Utilize several construction procedures in each bridge construction section, match the construction monitoring items for each construction procedure in a pre-defined list of bridge construction monitoring items, and obtain several construction monitoring points by calling the target construction bridge drawings to query the construction monitoring location of each construction monitoring item.

[0079] S220: Based on the planned time period for each construction procedure in each bridge construction section, determine the effective monitoring period for each construction monitoring point under each construction procedure.

[0080] In this embodiment, by calling a pre-defined list of bridge construction monitoring items, and using the construction monitoring items for each construction process recorded in the list, the construction monitoring points for each construction process in each bridge construction section are determined. Then, by combining the planned time period for each construction process, the effective monitoring time period for each construction monitoring point under each construction process is determined.

[0081] In a preferred embodiment, the steps of obtaining pre-defined bridge construction monitoring requirements, extracting monitoring type information and monitoring risk level for each construction monitoring point from the bridge construction monitoring requirements, considering the effective monitoring time period for each construction monitoring point, using the image acquisition distance interval corresponding to the monitoring type information and the image acquisition frequency interval corresponding to the monitoring risk level as constraints, and using the minimum flight distance as the optimization objective, to optimize the UAV image acquisition path planning strategy for the target construction bridge, specifically include:

[0082] S310: Obtain pre-defined bridge construction monitoring requirements, and extract monitoring type information and monitoring risk level for each construction monitoring point in the bridge construction monitoring requirements; wherein, the monitoring type includes several monitoring types of construction violations corresponding to different image acquisition distance intervals, and the monitoring risk level includes several monitoring risk levels of construction violations corresponding to different image acquisition frequency intervals;

[0083] S320: Using the monitoring type information and monitoring risk level, match the image acquisition distance and image acquisition frequency of each construction monitoring point in the first mapping table of preset monitoring type and image acquisition distance range and the second mapping table of preset monitoring risk level and image acquisition frequency range, respectively.

[0084] S330: Considering the effective monitoring period of each construction monitoring point, with the image acquisition distance range and the image acquisition frequency range as constraints, and with the minimum flight distance as the optimization objective, optimize and solve the UAV image acquisition path planning strategy for the target construction bridge.

[0085] Furthermore, considering the effective monitoring period for each construction monitoring point, and taking the image acquisition distance range and the image acquisition frequency range as constraints, with the minimum flight distance as the optimization objective, the optimization steps for solving the UAV image acquisition path planning strategy for the target construction bridge specifically include:

[0086] S331: Construct a three-dimensional model map of the target construction bridge, and generate the effective monitoring area of ​​each construction monitoring point in the three-dimensional model map based on the image acquisition distance range of each construction monitoring point;

[0087] S332: Obtain the flight speed range of the violation monitoring drone. Consider the effective monitoring period and effective monitoring area of ​​each construction monitoring point. Select several drone acquisition points within the effective monitoring period and effective monitoring area. Take the actual flight speed determined by the image acquisition interval time and image acquisition position of the two adjacent drone acquisition points in each drone image acquisition path as the first constraint condition. Take the image acquisition interval time of the two adjacent drone acquisition points of each construction monitoring point as the second constraint condition. Take the minimum sum of the flight distances of the violation monitoring drone in the generated drone image acquisition paths as the optimization objective. Optimize the solution of the image acquisition time and image acquisition position of each drone acquisition point in the several drone image acquisition paths.

[0088] S333: Based on the image acquisition time and location of each UAV acquisition point in several UAV image acquisition paths, generate a UAV image acquisition path planning strategy for the target construction bridge.

[0089] In this embodiment, after determining the effective monitoring period for each construction monitoring point, based on the monitoring type information and monitoring risk level of each construction monitoring point in the pre-defined bridge construction monitoring requirements, and considering the monitoring type information and monitoring risk level, the image acquisition distance range corresponding to the monitoring type information and the image acquisition frequency range corresponding to the monitoring risk level are used as constraints, and the flight distance is used as the optimization objective. The UAV image acquisition path planning strategy for the target construction bridge is optimized and solved. Finally, several UAV acquisition points used for UAV flight and image acquisition when monitoring bridge construction violations on the target construction bridge, as well as the image acquisition time and image acquisition location of each UAV acquisition point, are obtained. In this way, a construction image acquisition scheme with different monitoring distances and different monitoring frequencies that are suitable for different construction stages in the bridge construction process is obtained.

[0090] In a preferred embodiment, based on the UAV image acquisition path planning strategy, flight and image acquisition control commands are generated to drive the violation monitoring UAV to perform corresponding flight and image acquisition actions, and a bridge construction violation judgment step is performed based on the acquired bridge construction images, specifically including:

[0091] S410: Extract the image acquisition time and image acquisition position of each UAV acquisition point in each UAV image acquisition path in the UAV image acquisition path planning strategy, and calculate the flight speed between two adjacent UAV acquisition points in each UAV image acquisition path.

[0092] S420: Based on the image acquisition position of each UAV acquisition point and the flight speed between two adjacent UAV acquisition points, generate UAV flight control commands; based on the image acquisition time of each UAV acquisition point, generate UAV image acquisition commands; and obtain UAV flight and image acquisition control commands.

[0093] S430: Send the UAV flight and image acquisition control command to the violation monitoring UAV, drive the violation monitoring UAV to perform the corresponding flight and image acquisition actions, and perform a judgment on the bridge construction violation based on the acquired bridge construction images.

[0094] Based on this, after the violation monitoring drone completes each flight and image acquisition action, it obtains the bridge construction progress, updates the bridge construction plan information based on the bridge construction progress, and regenerates the drone image acquisition path planning strategy using the updated bridge construction plan information. Specifically, this includes:

[0095] S510: After the violation monitoring drone completes each flight and image acquisition action, it obtains the bridge construction progress of the target construction bridge and extracts the actual time period of the current construction procedure for each bridge construction section in the bridge construction progress.

[0096] S520: Based on the planned time period for executing each construction procedure in each bridge construction section in the bridge construction plan information and the actual time period for executing the construction procedure in each bridge construction section in the bridge construction progress, determine whether the time overlap ratio between the actual time period and the planned time period for executing the corresponding construction procedure is lower than the preset target ratio. If so, define the construction procedure corresponding to the actual time period as the error procedure.

[0097] S530: Determine whether the number of error procedures in the current construction process of each bridge construction section exceeds the preset target number. If so, update the bridge construction plan information based on the bridge construction progress, and regenerate the UAV image acquisition path planning strategy using the updated bridge construction plan information.

[0098] In this embodiment, after obtaining the UAV image acquisition path planning strategy for the target construction bridge, the flight speed between two adjacent UAV acquisition points in each acquisition path is calculated based on the image acquisition time and location of each acquisition point. This guides the UAV to perform corresponding flight and image acquisition actions. Simultaneously, considering the randomness of accidents during bridge construction, to avoid the impact of early or delayed completion of a construction procedure on subsequent UAV monitoring of bridge construction violations, this embodiment, after each flight and image acquisition action, needs to determine the difference between the actual time period of the current construction procedure in each bridge construction section and the planned time period for each construction procedure in each bridge construction section.
