Description

Technical Field

[0001] This invention relates to the field of monitoring, and in particular to a method for safety management of drone aerial photography. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of structures, or the process of turning the lines on design drawings into a physical object at a designated location. It includes foundation construction, main structure construction, roofing construction, and decoration construction. The site where construction work takes place is called a "construction site" or "building site."

[0003] As construction projects become larger and more complex, and design and construction technologies become more advanced, the relevant regulations become more detailed. Currently, safety inspections at construction sites mainly rely on regular or irregular patrols by safety personnel. However, due to the reasons mentioned above, it is difficult for personnel to conduct comprehensive inspections, which can easily lead to oversights and risks. Furthermore, some parts of many buildings are difficult for people to access, which adds to the difficulty of safety inspections.

[0004] Among existing conventional monitoring methods, drone monitoring is often the preferred method due to its high flexibility and minimal impact on the monitored object. However, because drones are more susceptible to interference than stationary monitoring, drone monitoring is typically used in operational systems rather than systems under construction.

[0005] To enable lightweight monitoring of the system under construction, a drone aerial photography safety management strategy is needed to meet the characteristics of construction sites with frequent rockfalls and projectiles. Summary of the Invention

[0006] This invention addresses the problem that while drone monitoring is a highly flexible and minimally impactful method often preferred in existing technologies, its higher susceptibility to interference compared to fixed monitoring often limits its application to operational systems rather than systems under construction. This invention provides a drone aerial photography safety management method that rationally plans risk areas at construction sites, thus resolving the aforementioned issues.

[0007] This invention provides a method for safety management of drone aerial photography, comprising the following steps: Step 1: Establish a construction site model. On the exterior of the construction site model, establish a model of the dangerous area of ​​the construction site according to the level of construction hazards and a model of the drone shooting path according to the shooting distance. Step 2: After superimposing the construction site hazard zone model and the drone shooting path model, remove the overlapping area to form a drone safety shooting model; Step 3: Based on the ideal shooting distance of the drone, attach the ideal shooting distance of the drone to the surface of the construction site model, use a cone-shaped perspective as the shooting angle, and scan the surface of the construction site horizontally back and forth to form the initial path of the drone. Step 4: Overlap the initial path of the drone with the safe shooting model of the drone, and take the overlapping part to obtain the breakpoint aerial shooting path model; Step 5: All connections must be made to the breakpoints in the same continuous area of ​​the drone's safe shooting model, and the connecting lines must be within the continuous area. Step 6: Output the connected path model as a safe aerial photography path model.

[0008] In the drone aerial photography safety management method of the present invention, as a preferred method, the connecting line connecting the breakpoints in step five prioritizes the surface of the continuous area as the path.

[0009] The present invention discloses a method for safe management of drone aerial photography. As a preferred method, the specific method for setting a construction site hazard zone model is as follows: setting a safety hazard level based on the construction site model, setting a hazard distance based on the safety hazard level, and superimposing the hazard distance on the construction site model to form a construction site hazard zone model. The specific method for obtaining the drone's shooting path model is to obtain the drone's shooting distance and then attach the drone's shooting distance to the surface of the construction site model to form the drone's shooting path model.

[0010] In a preferred embodiment of the UAV aerial photography safety management method of the present invention, both the construction site hazard zone model and the drone shooting path model are shell models attached to the construction site model.

[0011] The present invention provides a preferred method for managing the safety of drone aerial photography. The danger distance was determined by performing a 45-degree parabolic simulation based on the highest point of the edge, with the initial velocity set to 0. Take the highest point of each structure as an upward parabola, with an amplitude of 5 degrees and an initial velocity of 10 m / s; The speed is selected based on the mechanical projectile motion that may occur during actual construction, often based on a single floor. Assuming the average target height for a single staircase is 3-4 meters, and ignoring air resistance, the speed is determined by... (Pick The required minimum initial velocity is approximately 7~8 m / s; due to the efficiency of the action and the coordination of the catch, the actual manual throwing speed is estimated to be 5~10 m / s. The higher value is selected to obtain the necessary margin.

[0012] Imagine a parabola at a 30-degree angle to the top plane of each structure, with an initial velocity of 5 m / s.

[0013] The beneficial effects of this invention are as follows: By setting building hazard zones and standard drone aerial photography routes, an effective and safe monitoring area for drone surveillance is identified. Lateral scanning serves as the monitoring foundation. Hazard zone settings comprehensively consider the possibility of objects being thrown during construction, using the area covered by such objects as the basic hazard zone to prevent drones from being hit. Simultaneously, drones are kept as far away from the construction surface as possible to avoid interfering with construction. Considering these factors, this technical solution successfully enables drone monitoring to be implemented during system setup. Attached Figure Description

[0014] Figure 1 This is a flowchart of a method for safety management of drone aerial photography. Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0016] Example 1: like Figure 1 As shown, a method for safe management of drone aerial photography, when the method prioritizes data collection, i.e., when the drone can be discarded, Includes the following steps: Step 1: Establish a construction site model. On the exterior of the construction site model, establish a model of the dangerous area of ​​the construction site according to the level of construction hazards and a model of the drone shooting path according to the shooting distance. Step 2: After superimposing the construction site hazard zone model and the drone shooting path model, remove the overlapping area to form a drone safety shooting model; Step 3: Based on the ideal shooting distance of the drone, attach the ideal shooting distance of the drone to the surface of the construction site model, use a cone-shaped perspective as the shooting angle, and scan the surface of the construction site horizontally back and forth to form the initial path of the drone. Step 4: Overlap the initial path of the drone with the safe shooting model of the drone, and take the overlapping part to obtain the breakpoint aerial shooting path model; Step 5: All connections must be made to the breakpoints in the same continuous area of ​​the drone's safe shooting model, and the connecting lines must be within the continuous area. Step 6: Output the connected path model as a safe aerial photography path model.

[0017] This method uses the shortest connection method for routes that are still broken in the final route, ignoring the potential damage to the drone on site.

[0018] In step five, the connecting lines that connect the breakpoints prioritize the surface of the continuous region as the path.

[0019] The specific method for setting up a hazardous area model of a construction site is as follows: set the safety hazard level according to the construction site model, and set the hazardous area based on the safety hazard level. The specific method for obtaining the drone's shooting path model is to obtain the drone's shooting distance and then attach the drone's shooting distance to the surface of the construction site model to form the drone's shooting path model.

[0020] Both the construction site hazard zone model and the drone shooting path model are shell models attached to the construction site model.

[0021] Example 2 When the method prioritizes drone safety, drone safety is taken first, and other supplementary data collection methods are used for missed locations. This method includes the following steps: Step 1: Establish a construction site model. On the exterior of the construction site model, establish a model of the dangerous area of ​​the construction site according to the level of construction hazards and a model of the drone shooting path according to the shooting distance. Step 2: After superimposing the construction site hazard zone model and the drone shooting path model, remove the overlapping area to form a drone safety shooting model; Step 3: Based on the ideal shooting distance of the drone, attach the ideal shooting distance of the drone to the surface of the construction site model, use a cone-shaped perspective as the shooting angle, and scan the surface of the construction site horizontally back and forth to form the initial path of the drone. Step 4: Overlap the initial path of the drone with the safe shooting model of the drone, and take the overlapping part to obtain the breakpoint aerial shooting path model; Step 5: All connections must be made to the breakpoints in the same continuous area of ​​the drone's safe shooting model, and the connecting lines must be within the continuous area. Step 6: Output the connected path model as a safe aerial photography path model.

[0022] In this method, for routes that are still at a breakpoint in the final path, the drone avoids the danger zone and flies around its boundary to ensure drone safety. However, since the danger zone covers the entire shooting area, the lateral scanning process is interrupted, and the drone uses the same strategy to redeploy at the next breakpoint.

[0023] In step five, the connecting lines that connect the breakpoints prioritize the surface of the continuous region as the path.

[0024] The specific method for setting up a hazardous area model of a construction site is as follows: set the safety hazard level according to the construction site model, and set the hazardous area based on the safety hazard level. The specific method for obtaining the drone's shooting path model is to obtain the drone's shooting distance and then attach the drone's shooting distance to the surface of the construction site model to form the drone's shooting path model.

[0025] Both the construction site hazard zone model and the drone shooting path model are shell models attached to the construction site model.

[0026] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
