Description

Technical Field

[0001] The utility model relates to the technical field of remote sensing mapping, in particular to a remote sensing mapping device. Background Art

[0002] Remote sensing mapping is a technology that uses various sensors on the ground, aviation, and aerospace platforms to draw topographic maps or other thematic maps of the earth or other celestial bodies. Remote sensing mapping technology mainly refers to mapping using electromagnetic wave signals reflected, scattered, or emitted by ground objects received by sensors. The images obtained by remote sensing mapping are mainly frame cameras and CCD cameras. By obtaining overlapping stereo images in the heading or sideways along the flight direction or different orbits, the elevation of ground points and the topography are measured.

[0003] In the prior art, when low-altitude remote sensing mapping is performed by an aircraft, in order to improve the flight accuracy of the aircraft during mapping, image control points need to be deployed near the flight path, and the image control points are used as markers to guide and control the movement path of the aircraft. When deploying image control points in the field, the geological and geomorphological environment of the aerial survey area needs to be visually identified, and then the image control points are deployed in the aerial survey area using paint, target boards and other equipment. During the deployment process, it is best to deploy the target boards on a platform and horizontally.

[0004] According to a Chinese patent application number 202310455897.6, a remote sensing mapping device discloses a variety of installation methods when in use. However, after the installation is completed, there is no way to ensure that the target plate is level, that is, the marking surface is vertical up and down. Therefore, fine-tuning is still required during installation, which is more troublesome to operate. Therefore, an improved remote sensing mapping device is needed to address this problem. Utility Model Content

[0005] The purpose of the utility model is to provide a remote sensing mapping device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a remote sensing mapping device, comprising a column, a target plate is arranged on the upper end of the column, a mounting mechanism for packaging the target plate horizontally is arranged between the column and the target plate, the mounting mechanism comprises a connecting rod, a cross rod, a fixed sleeve, a movable sphere, and an extension rod, a connecting rod is fixedly arranged on the upper end of the column, a cross rod is fixedly arranged on the upper end of the connecting rod, a fixed sleeve is fixedly arranged on one end of the cross rod away from the connecting rod, a movable sphere is movably engaged with the interior of the fixed sleeve, an extension rod is fixedly arranged on the lower end of the movable sphere, and a connecting block is fixedly arranged between the movable sphere and the target plate.

[0007] Preferably, a foot is fixedly provided at the lower end of the column, which can provide a stable supporting force for the device, and the device can be installed regardless of whether the predetermined installation position is horizontal, because whether the column is vertical does not affect the horizontal state of the subsequent target plate.

[0008] Preferably, the upper and lower ends of the fixing sleeve are fixedly provided with limiting rings, and the limiting rings can be used to limit the movable ball so that the movable ball can only rotate in universal directions inside the fixing sleeve but cannot be separated.

[0009] Preferably, a first counterweight is fixedly provided at the lower end of the extension rod, and the weight of the first counterweight is greater than the weight of the target plate, and the weight is more than 20 times, so that under the action of gravity, the first counterweight can drive the target plate to always remain horizontal.

[0010] Preferably, a second counterweight is fixedly provided at the lower end of the column, and the second counterweight can ensure the overall center of gravity of the entire device to prevent the device from being unable to stand up normally. As long as the device can stand up normally, even if the column is tilted, the target plate of the device will remain horizontal and upward under the action of the first counterweight and the movable sphere that can rotate in all directions.

[0011] Preferably, a locking screw is provided on one side of the interior of the fixing sleeve through a threaded engagement, and the locking screw can be tightened after the target plate is stable and immobile, thereby squeezing the movable sphere, thereby locking the movable sphere so that the movable sphere no longer rotates.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The target plate of the device of the utility model can be kept horizontally upward under the action of the first counterweight block and the movable sphere that can be universally rotated. In this way, the device can automatically make the target plate vertically upward by using gravity, so that manual debugging is unnecessary. Even if the device is installed on a slope, the target plate of the device can still be upward, which is more convenient to install.

[0014] 1. The utility model can automatically drive the target plate vertically, so the requirements for the installation position are small, which can facilitate the planning of the installation point, so as to facilitate the identification of the aerial survey area during the remote sensing mapping of the UAV.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model provides a technical solution: a remote sensing mapping device, including a column 1, a target plate 2 is arranged on the upper end of the column 1, a mounting mechanism for packaging the target plate 2 horizontally is arranged between the column 1 and the target plate 2, the mounting mechanism includes a connecting rod 3, a cross bar 4, a fixed sleeve 5, a movable sphere 6, and an extension rod 7, the connecting rod 3 is fixedly arranged on the upper end of the column 1, the cross bar 4 is fixedly arranged on the upper end of the connecting rod 3, a fixed sleeve 5 is fixedly arranged on the end of the cross bar 4 away from the connecting rod 3, a movable sphere 6 is movably engaged with the inside of the fixed sleeve 5, an extension rod 7 is fixedly arranged on the lower end of the movable sphere 6, and a connecting block 13 is fixedly arranged between the movable sphere 6 and the target plate 2.

[0022] The lower end of the column 1 is fixedly provided with a support foot 11, which can provide a stable support force for the device, and the device can be installed regardless of whether the predetermined installation position is horizontal, because whether the column 1 is vertical does not affect the horizontal state of the subsequent target plate 2;

[0023] The upper and lower ends of the fixed sleeve 5 are fixedly provided with limit rings 8, and the limit rings 8 can be used to limit the movable ball 6 so that the movable ball 6 can only rotate in universal directions inside the fixed sleeve 5, but cannot be separated;

[0024] A first counterweight 9 is fixedly disposed at the lower end of the extension rod 7. The weight of the first counterweight 9 is greater than the weight of the target plate 2, and the weight is more than 20 times greater. In this way, under the action of gravity, the first counterweight 9 can drive the target plate 2 to always remain horizontal.

[0025] A second counterweight 10 is fixedly provided at the lower end of the column 1, and the second counterweight 10 can ensure the overall center of gravity of the entire device, preventing the device from being unable to stand up normally. As long as the device can stand up normally, even if the column 1 is tilted, the target plate 2 of the device will remain horizontal and upward under the action of the first counterweight 9 and the movable ball 6 that can be universally rotated;

[0026] A locking screw 12 is provided on one side of the interior of the fixing sleeve 5 through a threaded engagement. The locking screw 12 can be tightened after the target plate 2 is stable and immobile, thereby squeezing the movable sphere 6, thereby locking the movable sphere 6 so that the movable sphere 6 no longer rotates.

[0027] Working principle: When using the device, the support feet 11 can be used to fix the device at the target position. Subsequently, no matter whether the installation position is horizontal or whether there are holes in the installation position, the target plate 2 of the device can always be horizontally upward under the action of the installation mechanism; the target plate 2 of the device will remain horizontally upward under the action of the first counterweight block 9 and the movable ball 6 that can be universally rotated; the principle is that the weight of the first counterweight block 9 is much larger than the target plate 2, and it is a regular shape, and it can automatically tend to be vertically downward under the action of its own gravity; in this way, the weight of the target plate 2 is much smaller than the target plate 2, and its weight has little effect on the automatic vertical downward tendency of the first counterweight block 9. In this way, the device can automatically make the target plate 2 vertically upward by gravity, so that there is no need for manual debugging. Even if the device is installed on a slope, the target plate 2 of the device can still be upward, so it is more convenient to install.

[0028] Furthermore, since the device can automatically drive the target plate 2 to be vertical, the requirements for the installation position are relatively small, and it is easy to plan the installation point to facilitate the identification of the aerial survey area during the remote sensing mapping of the unmanned aerial vehicle.
