Description

Technical Field

[0001] The present invention relates to the technical field of remote sensing mapping markers, and specifically to a remote sensing mapping device based on urban and rural different terrain planning. Background Art

[0002] Surveying and mapping covers two key aspects: measurement and mapping. It is firmly based on computer technology, optoelectronic technology, network communication technology, space science, and information science. At the same time, it takes the Global Navigation Satellite System (GNSS), Remote Sensing (RS), and Geographic Information System (GIS) as the core technical supports. By using these advanced technologies, surveying and mapping work can accurately select existing feature points and boundaries on the ground, and then, with the help of professional measurement means, obtain graphics, positions, and various detailed information related to them that reflect the current situation of the ground. These information are of extremely high value, can provide accurate data support for engineering construction to ensure the smooth progress of engineering projects; can provide comprehensive basic data for planning and design to make the planning more scientific and reasonable; and can also provide important decision-making basis for administrative management to help the orderly development of cities.

[0003] Aerial survey by aircraft, as a new emerging low-altitude remote sensing image acquisition technology, is a powerful supplement to traditional satellite remote sensing and aerial photography. With its unique advantages, it can quickly and efficiently obtain high-resolution orthophoto maps of small-scale areas and areas difficult to photograph. In many fields of national economic construction, such as urban planning, land resource management, disaster monitoring and assessment, etc., aerial survey by aircraft plays a crucial role and provides important technical support for promoting the development of the economic society.

[0004] In the whole process of aerial survey by aircraft, the layout of image control points is a crucial link. Whether the target selection of image control points is appropriate and the accuracy of indicating the point positions will directly affect the accuracy of the measurement results. Image control points are mainly divided into two types: target-type image control points and paint-type image control points. Target-type image control points do not require spraying operations and can be directly placed in the survey area. After the aerial survey aircraft finishes its operation, they can be recycled on the spot, which has the advantages of low carbon and environmental protection, so they are widely used.

[0005] Existing targets have been greatly improved. Compared with traditional cloth targets, they can better fit the ground and can withstand the influence of some natural environments such as wind, ensuring that the targets will not shift during the process of surveying and mapping markers. However, for projects with a large survey area, the number of required targets is huge. A large number of targets are independently set up with each other and lack connection, which is not conducive to handling and transfer, resulting in difficulties in remote sensing mapping markers. Summary of the Invention

Detailed implementation manners

[0032] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0033] As Figures 1 to 9 shown, the present invention includes the following embodiments:

[0034] Embodiment 1: A remote sensing mapping device based on different urban and rural terrains includes a base 1 and four skeletons 2 hinged to the lower surface of the base 1 through torsion springs 11; the ends of two opposite skeletons 2 away from the base 1 protrude outwardly with clamping blocks 21; adjacent two of the skeletons 2 are connected with sub-target plates 31, and the four sub-target plates 31 are combined into a whole target plate 3 after the four skeletons 2 are unfolded; the torsion springs 11 can drive the corresponding skeletons 2 to unfold; the upper surface of the base 1 is provided with a circular groove 12; the groove wall of the circular groove 12 is provided with an annular clamping groove 13; the clamping block 21 on one remote sensing mapping device can be clamped into the clamping groove 13 on another remote sensing mapping device after the skeleton 2 is folded.

[0035] In the folded state, the clamping block 21 on one of the remote sensing mapping devices can be inserted into the clamping groove 13 on the other remote sensing mapping device, so as to realize the head-to-tail connection of the remote sensing mapping devices, so that multiple remote sensing mapping devices are connected in series into a whole. Therefore, when taking one of the remote sensing mapping devices, it can drive other remote sensing mapping devices to move, which is convenient for the transfer and handling of the remote sensing mapping devices. After using the measuring instrument to measure the position to be marked, move the multiple series-connected remote sensing mapping devices to the position to be located. Then, simultaneously press the two frameworks 2 with the clamping block 21 inserted into the circular groove 12. After pressing, the two opposite frameworks 2 will approach each other and drive the two clamping blocks 21 to move out of the clamping groove 13, so that the two connected remote sensing mapping devices are unlocked. Then, pull out the unlocked framework 2 from the circular groove 12 to realize the independence of the remote sensing mapping device. Then, release the four frameworks 2, and the four frameworks 2 will expand under the torque of the corresponding torsion springs 11. One end of the framework 2 connected to the base 1 is hinged to the lower surface of the base 1 through the torsion spring 11, and there is a distance between the end of the framework 2 connected to the base 1 and the edge of the base 1. Therefore, under the action of the torsion spring 11, the four frameworks 2 are unfolded horizontally. During the unfolding process of the four frameworks 2, the four sub-target plates 31 will be unfolded. The sub-target plates 31 are made of flexible materials such as cloth. After the four sub-target plates 31 are unfolded, they will form a complete whole target plate 3. Two of the opposite target plates are red, and the other two opposite target plates are white. Place the base 1 at the center of the surveying and mapping positioning to complete the marking and positioning of the remote sensing mapping; when the remote sensing mapping device is recycled after use, only need to fold the four frameworks 2 downward against the corresponding torsion springs 11 towards the base 1, so that the four frameworks 2 are folded up, and the sub-target plates 31 are folded up with the folding of the frameworks 2. One end of the four frameworks 2 away from the base 1 has an outward expansion force brought by the torsion spring 11. After the four frameworks 2 are inserted into the circular groove 12, release the frameworks 2, and the clamping blocks 21 on the two opposite frameworks 2 will be inserted into the clamping groove 13, so that multiple remote sensing mapping devices are connected in series; a single remote sensing mapping device can also be folded up by tying with a rope; in the present invention, the clamping block 21 on one of the remote sensing mapping devices can be inserted into the clamping groove 13 on the other remote sensing mapping device after the framework 2 is folded, so that multiple remote sensing mapping devices are connected in series, which is convenient for the taking and transfer of the remote sensing mapping devices and meets the outdoor use requirements.

[0036] Embodiment 2: Shading grooves 22 are arranged on both sides of the framework 2; an arc-shaped shading plate 23 is slidably connected in the shading grooves 22; the shading plate 23 is connected to the bottom of the shading grooves 22 through a first spring 24.

[0037] During the folding process of the four frameworks 2 against the corresponding torsion springs 11, the sub-target plates 31 are folded as the frameworks 2 are folded. The sub-target plates 31 will be folded to the inner sides of the four frameworks 2. The gaps between adjacent frameworks 2 are blocked by the retractable baffle plates 23, thereby protecting the sub-target plates 31 inside the four frameworks 2 and preventing the sub-target plates 31 from being scratched during the transfer of the remote sensing mapping device. The baffle plates 23 on adjacent two frameworks 2 are in contact with each other. The baffle plates 23 on the frameworks 2 can be retracted, so that during the further approaching process of the two opposite frameworks 2, the baffle plates 23 can be retracted into the corresponding blocking grooves 22 against the first springs 24, enabling the four frameworks 2 to be pinched and approached without affecting the unlocking of the clamping blocks 21 on the frameworks 2 in the clamping grooves 13.

[0038] Embodiment 3: An extension groove 25 is provided at one end of the framework 2 away from the base 1; an extension bar 4 is slidably connected in the extension groove 25.

[0039] In this embodiment, the extension groove 25 is slidably and sealingly connected to the extension bar 4; a driving groove 14 is provided inside the base 1; a driving plate 5 is slidably and sealingly connected in the driving groove 14; a one-way air inlet hole 51 is vertically penetrated through the driving plate 5; a third spring 52 is connected between the lower surface of the driving plate 5 and the lower end surface of the driving groove 14; the upper end surface of the driving groove 14 is communicated with the bottom of the circular groove 12 through a ventilation hole 15; the lower end surface of the driving groove 14 is communicated with the bottom of the extension groove 25 through a one-way air outlet hole 16; a driving rod 53 is fixedly connected to the upper surface of the driving plate 5; the driving rod 53 extends upward through the base 1 to the outside; the driving rod 53 is slidably and sealingly connected to the base 1.

[0040] In this embodiment, a pressure relief groove 26 is provided on the outer wall of the framework 2; a pressure relief block 6 is slidably and sealingly connected in the pressure relief groove 26; a second spring 61 is connected between the pressure relief block 6 and the bottom of the pressure relief groove 26; the groove wall of the pressure relief groove 26 is communicated with the bottom of the extension groove 25 through a first pressure relief hole 27; an L-shaped second pressure relief hole 62 is provided for communicating the outer wall and the inner wall of the pressure relief block 6; when the pressure relief block 6 is extruded by the base 1, the second pressure relief hole 62 is offset from the first pressure relief hole 27; a first tension spring 41 is connected between the bottom of the extension groove 25 and the extension bar 4.

[0041] After the skeleton 2 is moved out of the circular groove 12, the skeleton 2 is released, and the skeleton 2 will flip under the torsion of the corresponding torsion spring 11, and the four skeletons 2 will drive the sub-target pieces 31 to unfold. During the flipping and unfolding process of the skeleton 2, the pressure relief block 6 will be driven to press against the lower surface of the base 1. The pressure relief block 6 will overcome the second spring 61 and slide along the pressure relief groove 26 under the compression of the base 1. The bottom of the pressure relief groove 26 is connected, so the gas in the pressure relief groove 26 will be squeezed out during the pressure relief block 6 entering the pressure relief groove 26. After the pressure relief block 6 moves, it will drive the second pressure relief hole 62 to stagger with the first pressure relief hole 27, so that the gas in the extension groove 25 cannot be depressurized. After the sub-target sheet 31 is fully unfolded, the base 1 is placed at the surveying and positioning point, and the driving rod 53 is stepped on intermittently repeatedly. During the downward movement of the driving rod 53, the driving plate 5 is driven to move downward, and the driving plate 5 divides the driving groove 14 into an upper cavity and a lower cavity. During the downward movement of the driving plate 5, the space in the lower cavity becomes smaller and the air pressure increases. The gas in the lower cavity enters the extension groove 25 along the one-way air outlet 16. After the driving rod 53 is released, the third spring 52 drives the driving plate 5 to move upward. During the upward movement of the driving plate 5, the driving rod 53 is driven upward. During the upward movement of the driving plate 5, the space in the lower cavity becomes larger to form a negative pressure. The boundary gas will enter the lower cavity along the circular groove 12, the air vent 15, the upper cavity and the one-way air inlet 51, so that the gas in the lower cavity is replenished. As the driving plate 5 moves downward again, the gas in the lower cavity will enter the extension groove 25 along the one-way air outlet 16. The amount of gas in the extension groove 25 increases, and the air pressure increases. In this way, the extension bar 4 is pushed by the air pressure to slide along the extension groove 25. The extension bar 4 will overcome the tension of the first tension spring 41 in the extension groove 25 and extend out. After the extension bar 4 extends out of the extension groove 25, the length of the frame 2 is extended, so that the placement range of the frame 2 on the ground is expanded, thereby improving The entire target piece 3 is placed more stably and is not prone to displacement, making remote sensing mapping more accurate; when the skeleton 2 overcomes the corresponding torsion spring 11 to fold, the skeleton 2 will drive the pressure relief block 6 to break away from contact with the base 1, and the pressure relief block 6 will slide outward along the pressure relief groove 26 under the elastic force of the second spring 61. After the pressure relief block 6 moves, the second pressure relief hole 62 will be aligned with the first pressure relief hole 27, so that the gas in the extension groove 25 is connected to the outside world, so that the first tension spring 41 will pull the extension strip 4 back to the extension groove 25, and the gas in the extension groove 25 will be discharged along the first pressure relief hole 27 and the second pressure relief hole 62.

[0042] Embodiment 4: A piercing hole 42 is provided on the side of the extension strip 4 that contacts the ground; a piercing rod 43 is slidably and sealedly connected inside the piercing hole 42; and the bottom of the piercing hole 42 is connected to the inside of the extension groove 25 via a diversion hole 44.

[0043] In this embodiment, the piercing rod 43 is connected to the bottom of the piercing hole 42 via a second tension spring 45 ; the tension of the second tension spring 45 is smaller than the tension of the first tension spring 41 .

[0044] In this embodiment, an embedding groove 46 is provided on the surface of the extension bar 4 in contact with the ground; the punching hole 42 is provided at the bottom of the embedding groove 46; an embedding plate 47 is hinged in the embedding groove 46; the embedding plate 47 can be tilted and unfolded under the push of the punching rod 43; the tilting direction of the unfolded embedding plate 47 is away from the base 1; the embedding groove 46 is provided at one end of the extension bar 4 away from the first tension spring 41.

[0045] In the process that the gas in the driving groove 14 enters the extension groove 25 along the one-way air outlet 16, the gas in the extension groove 25 will enter the puncture hole 42 along the diverter hole 44. The air pressure in the puncture hole 42 increases as the air pressure in the extension groove 25 increases. The tension of the second tension spring 45 is less than the tension of the first tension spring 41, so that when the extension bar 4 is pushed by the air pressure, the puncture rod 43 will move away from the bottom of the puncture hole 42. Due to the blocking of the embedded plate 47 in the embedded groove 46, the puncture rod 43 will not extend out of the puncture hole 42, thereby protecting the inner wall of the extension groove 25 and preventing the inner wall of the extension groove 25 from being scratched by the puncture rod 43. As the air pressure in the extension groove 25 increases, the extension bar 4 is compressed to overcome the tension of the first tension spring 41 and move along As the extension groove 25 slides, the extension bar 4 can slide in the extension groove 25 but will not fall off the connection. During the outward expansion of the extension bar 4, the tying rod 43 and the embedding groove 46 will be driven out of the extension groove 25. After the embedding groove 46 is exposed from the extension groove 25, the tying rod 43 will be affected by the air pressure and overcome the tension of the second tension spring 45 to slide outward along the tying rod 43. The tying rod 43 can slide in the piercing hole 42 but will not be separated from the piercing hole 42. The sliding connection means that it can slide but will not be separated. During the process of the tying rod 43 extending out of the piercing hole 42, the embedding plate 47 will be squeezed. The inner side of the embedding plate 47 will be pressed and turned over. The inner side of the embedding plate 47 is squeezed by the tying rod 43 and turned over to be inclined. As the extension bar 4 As the extension bar 4 continues to move outward, the extension bar 4 will drive the lower surface inclined embedding plate 47 away from the base 1. The inclined embedding plate 47 will penetrate into the soft ground, such as soil or grass, etc., as the extension bar 4 expands outward, thereby achieving the locking of the extension bar 4 and the ground. The four extension bars 4 all drive the embedding plate 47 to be tilted outward and inserted into the ground. In this way, the remote sensing and mapping equipment needs to overcome the resistance of the embedding plate 47 no matter which direction it moves. The fixing effect of the inclined insertion into the ground is better than that of the vertical insertion into the ground, so that the force required for the displacement of the remote sensing and mapping equipment is greater. In this way, the extension bar 4 can be expanded outward and the embedding plate 47 can be inserted into the ground by repeatedly and intermittently pressing the driving rod 53, thereby improving the remote sensing and mapping equipment. Stability of connection with the ground; when the remote sensing mapping equipment is recovered, it is only necessary to remove the soil or grass around the embedded strip, lift the base 1, and flip the frame 2, so that the extension groove 25 is connected to the outside through the first pressure relief hole 27 and the second pressure relief hole 62. As the air pressure in the extension groove 25 and the piercing hole 42 decreases, the second tension spring 45 will pull the piercing rod 43 back into the piercing hole 42, and the first tension spring 41 will pull the extension strip 4 back into the extension groove 25. The extension strip 4 will drive the embedded plate 47 to enter the extension groove 25. The embedded plate 47 is squeezed by the notch of the extension groove 25 and enters the embedded groove 46 for avoidance until the extension strip 4 is completely retracted into the extension groove 25, completing the folding of the extension strip 4.

[0046] Embodiment 5: One end of the driving rod 53 away from the driving plate 5 is fixedly connected to the pedal 7; two first slots 71 and two second slots 72 are symmetrically arranged on the outer wall of the pedal 7; the connection line of the two first slots 71 is perpendicular to the connection line of the two second slots 72; the cross-section of the first slot 71 is adapted to the cross-section of the framework 2; the depth of the second slot 72 is greater than that of the first slot 71.

[0047] After both remote sensing mapping devices are folded, insert the ends of the two frameworks 2 without the clamping blocks 21 in one of the remote sensing mapping devices into the first slots 71, and insert the ends of the two frameworks 2 with the clamping blocks 21 in this remote sensing mapping device into the second slots 72. Then, pinch the two frameworks 2 with the clamping blocks 21 until the ends of the frameworks 2 completely enter the circular grooves 12, and then release the frameworks 2. The frameworks 2 drive the clamping blocks 21 to be stuck into the clamping grooves 13 under the torsion of the torsion springs 11, realizing the head-to-tail connection of the two independent remote sensing mapping devices. The first slots 71 limit the other two frameworks 2 without the clamping blocks 21, so that the ends of the frameworks 2 cannot be displaced in the circular grooves 12, making the connection of adjacent remote sensing mapping devices more stable. An annular rope can be sleeved outside the four frameworks 2, so that the annular rope can be moved around the clamping blocks 21 during the folding process, so that a single remote sensing mapping device can be folded independently. During the unfolding process of the frameworks 2, the annular sleeve is moved to the lower surface position of the base 1, which does not prevent the unfolding of the frameworks 2.

[0048] Embodiment 6: The extension bar 4 is composed of a near spring bar 48 and a far spring bar 49; the near spring bar 48 is connected to the first tension spring 41; the far spring bar 49 is rotationally and sealingly connected to the near spring bar 48; the shunt hole 44 is eccentrically arranged in the extension bar 4; the punching hole 42 and the embedding groove 46 are arranged on the far spring bar 49.

[0049] In the case of outdoor wilderness, just keep the embedding groove 46 facing the ground. At this time, the shunt holes 44 on the near spring bar 48 and the far spring bar 49 are aligned and kept communicating, so that the punching hole 42 is kept communicating with the extension groove 25, driving the punching rod 43 and the embedding plate 47, and realizing the insertion of the embedding plate 47 into the ground. In the case of using on hard ground such as urban cement, after the far spring bar 49 moves out of the extension groove 25, pinch the embedding plate 47 and press it into the embedding groove 46, and then rotate the far spring bar 49 to stagger the shunt hole 44 on the far spring bar 49 from the shunt hole 44 on the near spring bar 48 until the embedding groove 46 faces away from the ground, so that the punching hole 42 is disconnected from the extension groove 25. In this way, the embedding plate 47 cannot be removed from the embedding groove 46, making the surface of the extension bar 4 flat, and making the sub-target pieces 31, the frameworks 2 and the extension bar 4 better adhere to the ground, thus meeting the mapping markings of different terrains in urban and rural areas.
