Description

Technical Field

[0001] This application relates to the field of ground positioning tools for unmanned aerial vehicles (UAVs), and more specifically, to a control point structure. Background Technology

[0002] In fields such as UAV aerial photogrammetry, oblique photogrammetry modeling, and remote sensing mapping, control points (APIs) are a key infrastructure for high-precision geolocation and model geometric correction. Typically, APIs are laid out on the ground with clear and regular geometric patterns so that aerial photography equipment carried by UAVs can clearly identify and accurately locate their center points from the air.

[0003] When workers lay the control point body on the ground, they first use a level to determine if the ground is flat. If the ground is flat, the workers will lay the control point body on the ground and then use water bags to press down on the four ends of the control point to fix it. However, the water bags only cover the four corners of the control point, and the middle area of ​​the edge of the control point body is not compressed. Strong winds can easily enter between the control point and the ground from the uncompressed area, causing the water bags on the control point body to be under local pressure and roll. This eventually causes the control point body to tilt. After the control point body tilts, the workers need to use the level to measure again and lay the control point body again, which is too cumbersome. Utility Model Content

This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0008] Furthermore, the support leg is rotatably connected to the fixed base; the fixed base is provided with a receiving area for accommodating the support leg.

[0009] Furthermore, the outrigger is provided with a mounting plate; the side of the mounting plate facing the ground is provided with multiple sharp points.

[0010] Furthermore, the support leg is detachably connected to the mounting plate.

[0030] Reference Figure 1-4 ,

[0031] An image control point (AVB) structure includes: an ADB body 1, a bubble level 2, and a water bag 3. Specifically, the ADB body 1 is made of plastic, and the water bag 3 is made of TPU. The ADB body 1 has a cross-shaped pattern 11 for drone positioning and marking. The water bag 3 is positioned on the ADB body 1 around the edge of the cross-shaped pattern 11. In other embodiments, the water bag 3 is attached to the ADB body 1 with Velcro. However, considering the limited lifespan of Velcro, in this embodiment, the edge of the cross-shaped pattern 11 is provided with a groove that conforms to the outer wall of the water bag 3. The water bag 3 is directly attached to the groove and fixedly connected to the ADB body 1. The bubble level 2 is positioned at the center of the cross-shaped pattern 11. With the bubble level 2 positioned at the center of the cross-shaped pattern 11, workers can directly determine whether the ADB body 1 is level during installation using the bubble level. The water bag 3 is placed around the edge of the cross-pattern 11 to form a closed counterweight ring, completely sealing the gap between the control point body 1 and the ground. This prevents strong winds from entering the area between the control point and the ground from the un-covered area, thus preventing the control point body 1 from tilting and eliminating the need for re-laying. The operation is simple. The water bag 3 is equipped with a water inlet and a plug for sealing the water inlet.

[0032] During use, workers can first place the image control point body 1 on the ground and judge whether the ground is flat by observing the bubble level 2 on the image control point body 1. Then, fill the water bag 3 with water through the water inlet and then block the water inlet with the plug.

[0033] Specifically, refer to Figure 2 The image control point structure also includes: a fixed base 4 and support legs 5; the image control point body 1 has a protrusion 12 on the side facing away from the water bag 3; the protrusion 12 is a block structure. The fixed base 4 has a slot 41; the protrusion 12 matches the shape of the slot 41; at least three support legs 5 are provided on the fixed base 4, and in this embodiment, four support legs 5 are provided. The support legs 5 are used to contact the ground. When the image control point body 1 is laid on some wet soil roads, the wet soil sticks to the image control point body 1, which will cause the aerial photography equipment to be unable to clearly identify and accurately locate the center point from the air. Therefore, in this embodiment, the fixed base 4 and support legs 5 are set below the image control point body 1 so that the image control point body 1 can maintain a certain distance from the ground to prevent wet soil from adhering to the image control point body 1. During use, the user can first place the image control point body 1 on the fixed base 4 and make the support legs 5 on the fixed base 4 contact the ground. Users can observe the bubble level 2 on the control point body 1 to check whether the road surface where the fixing seat 4 is placed is flat, and then determine whether the position of the fixing seat 4 needs to be adjusted.

[0034] Specifically, refer to Figure 3The support leg 5 is rotatably connected to the fixed base 4; the fixed base 4 is provided with a receiving area 42 for receiving the support leg 5. During carrying, the user can rotate the support leg 5 into the receiving area 42 to make the fixed base 4 easy to carry.

[0035] Specifically, refer to Figure 4 The outrigger 5 is equipped with a mounting plate 51; the side of the mounting plate 51 facing the ground has multiple sharp points 511. The sharp points 511 are block-shaped structures with a tapered longitudinal section. The sharp points 511 are designed to give the outrigger 5 better grip. On some wet surfaces, the sharp points 511 can be directly inserted into the ground to enhance the overall stability of the mounting base 4.

[0036] Specifically, refer to Figure 4 The support leg 5 is detachably connected to the mounting plate 51. Specifically, the support leg 5 is plugged into and fixed to the mounting plate 51. In some special cases, such as when the control point body 1 is directly laid on the roof, in order to prevent the sharp part 511 from scratching the vehicle surface, the support leg 5 and the mounting plate 51 are detachably connected in this embodiment. At the same time, when the sharp part 511 is contaminated with mud, the user can remove the mounting plate 51 from the support leg 5 and then clean the mud off the sharp part 511.

[0037] Specifically, refer to Figure 4 The fixed base 4 is provided with an inclined surface 43. When the support leg 5 abuts against the inclined surface 43, the support leg 5 is inclined at 40-80° relative to the ground. Specifically, the support leg 5 is inclined at 80° relative to the ground. The inclined surface 43 is used to limit the movement of the support leg 5.

[0038] Specifically, refer to Figure 2 The fixed base 4 is provided with at least two gripping parts 44 for hand gripping, and the gripping parts 44 are located on both sides of the fixed base 4. In this embodiment, two gripping parts 44 are provided. After the user places the fixed base 4 on the ground, the user can use the bubble level 2 to determine whether the ground is level. If it is not level, the user can hold the gripping parts 44 to adjust the position of the fixed base 4.

[0039] Specifically, the accommodating area 42 is designed to reduce the overall weight of the mounting base 4. The slot 41 is located above the support leg 5. After the support leg 5 is extended relative to the mounting base 4, the protrusion 12 abuts against the support leg 5, and the support leg 5 also abuts against the inclined surface 43. In this embodiment, both the mounting base 4 and the support leg 5 are made of plastic.
