Description

Technical Field

[0001] The utility model relates to the technical field of aerial photography equipment, in particular to an unmanned aerial vehicle (UAV) aerial photography ground target for measurement. Background Technique

[0002] With the rapid development of economic construction, the landforms of various regions have undergone great changes, and new features have emerged on some maps. Accurate and complete geographical data plays a promoting role in the economic construction of regions. Therefore, it is necessary to update the old geographical data. However, the existing aerial photography technical means can no longer meet the needs of economic development. Therefore, the technology with the UAV as the aerial remote sensing platform is a new type of applied technology developed to meet this need, which can better meet the current demand for aerial remote sensing services in China.

[0003] When measuring the ground by UAV aerial photography, the staff controls the UAV to perform triangulation on the ground, and then processes the data obtained from the aerial photography in the later stage. However, the accuracy of the later processing is not high. One of the main reasons is the lack of ground control points. Especially in deserts, fields, and grasslands, there are no obvious targets, which will lead to low data accuracy of aerial photography. Therefore, it is necessary to place targets at corresponding positions on the ground.

[0004] The existing ground target is generally placed on the ground through a tripod. Due to the low stability of the tripod on the ground, it is easily affected by the external environment, resulting in the inclination of the target or even the collapse of the target. Content of the Utility Model

[0005] The purpose of the utility model is to provide an unmanned aerial vehicle (UAV) aerial photography ground target for measurement, so as to solve the problem that the existing ground target has low stability, resulting in easy inclination or even collapse of the target.

[0006] To achieve the above object, the basic scheme provided by the utility model is: including a base and a first anti-collapse component. A support rod is fixedly connected to the base. The end of the support rod away from the base is detachably connected with a target board. The first anti-collapse component includes two telescopic rods. Two connecting blocks are arranged on the base. A collar is movably sleeved on the outer wall of the support rod. The two ends of each telescopic rod are respectively hinged to the collar and the connecting block. A second anti-collapse component for fixing the base to the ground is arranged on the base.

[0007] The working principle of the utility model: When the target is needed, first place the device on the ground so that the base contacts the ground, and then slide the collar upward along the support rod to stretch the telescopic rod hinged to the surface of the collar to the limit, and the installation of the target can be completed; when the target is not needed, slide the collar downward along the support rod until the telescopic rod is compressed to the limit.

[0008] Beneficial effects: By setting up the first anti - tipping component to form a triangular fixed base, it changes the previous support method with a single support rod, avoiding the equipment from being prone to tilting under the influence of bad weather and improving the stability of the target; by setting up the second anti - tipping component, it further guarantees the stability of the target.

[0009] Solution two, which is the preference of the basic solution. The second anti - tipping component includes two chains and steel pins. There are bumps on both sides of the base, and both ends of each chain are respectively connected to the bump and the steel pin; setting up the second anti - tipping component on the base is to further optimize the stability of the target.

[0010] Solution three, which is the preference of solution two. There is a hole for embedding the steel pin on the side of the base, and the hole and the bump are on the same side; setting up the hole on the base is to facilitate the collection of the steel pins.

[0011] Solution four, which is the preference of solution two. There is a magnetic ring at the port of the hole; setting up the magnetic ring at the port of the hole is to prevent the steel pin from falling.

[0012] Solution five, which is the preference of the basic solution. There is a screw at the bottom of the target board, and there is a square block at the end of the support rod away from the base. There is a threaded hole for threaded connection with the screw on the square block; setting the target board and the support rod to be detachable is to facilitate the replacement of the target board.

[0013] Solution six, which is the preference of the basic solution. The surface of the target board is coated with a corrosion - resistant layer, the surface of the corrosion - resistant layer is coated with a waterproof layer, and the surface of the waterproof layer is coated with a reflective layer; setting up the corrosion - resistant layer and the waterproof layer on the target board is to protect the surface of the target board 401, and setting up the reflective layer is to reflect the target board, which is used to improve the reflective intensity of the ground target, so as to improve the accuracy of aerial photogrammetry data.
