Description

Technical Field

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

[0002] Surveying and mapping covers two key aspects: measurement and drawing. It has a solid foundation in computer technology, optoelectronic technology, network communication technology, space science, and information science, and is supported by the Global Navigation Satellite Positioning System (GNSS), remote sensing (RS), and geographic information system (GIS). By applying these advanced technologies, surveying and mapping work can accurately select existing feature points and boundaries on the ground, and then use professional measurement methods to obtain graphics, locations, and various related detailed information that reflect the current status of the ground. This information is extremely valuable and can provide accurate data support for engineering construction, ensuring the smooth implementation of engineering projects; provide comprehensive basic data for planning and design, making planning more scientific and reasonable; and provide important decision-making basis for administrative management, contributing to the orderly development of cities.

[0003] As an emerging low-altitude remote sensing image acquisition technology, aircraft-based aerial surveying is a powerful complement to traditional satellite remote sensing and aerial photography. Leveraging its unique advantages, it can quickly and efficiently acquire high-resolution orthophotos of small areas and areas difficult to access via aerial photography. Aerial surveying plays a vital role in numerous areas of national economic development, such as urban planning, land resource management, and disaster monitoring and assessment, providing crucial technical support for promoting economic and social development.

[0004] The placement of image control points (GCPs) is a crucial step in the entire aerial survey process. The appropriate selection of GCPs and the accuracy of their positional indications directly impact the accuracy of the measurement results. GCPs are primarily categorized as target-type and paint-type. Target-type GCPs require no painting and can be placed directly within the survey area. They can also be recovered on-site after the survey aircraft is completed, offering low-carbon and environmentally friendly advantages, leading to their widespread use.

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

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

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

[0034] Example 1: A remote sensing mapping device based on different urban and rural terrain planning includes a base 1 and four skeletons 2 hinged to the lower surface of the base 1 through a torsion spring 11; two of the skeletons 2 are provided with a card block 21 protruding outward at one end away from the base 1; two adjacent skeletons 2 are connected to sub-target pieces 31, and the four sub-target pieces 31 are combined into a whole target piece 3 after the four skeletons 2 are unfolded; the torsion spring 11 can drive the corresponding skeleton 2 to unfold; a circular groove 12 is provided on the upper surface of the base 1; the groove wall of the circular groove 12 is provided with an annular card groove 13; the card block 21 on one remote sensing mapping device can be stuck in the card slot 13 on another remote sensing mapping device after the skeleton 2 is folded.

[0035] In the folded state, the card block 21 on one of the remote sensing mapping devices can be inserted into the card slot 13 on another remote sensing mapping device, thereby realizing 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. When one of the remote sensing mapping devices is taken, the other remote sensing mapping devices can be driven to move, thereby facilitating the transfer and transportation of the remote sensing mapping devices. After the position to be marked is measured using the measuring instrument, the multiple remote sensing mapping devices in series are moved to the position to be positioned, and then the two inserted into the circular groove 12 and with the card block 21 are pressed at the same time. The two relative frames 2 will move closer to each other after being pressed and drive the two card blocks 21 to move out of the card slots 13, thereby unlocking the two connected remote sensing mapping devices. Then, the unlocked frames 2 will be pulled out from the circular slots 12 to realize the independence of the remote sensing mapping devices. Then, the four frames 2 will be loosened. The four frames 2 will be stretched open under the torsion of the corresponding torsion springs 11. The frames 2 and the lower surface of the base 1 are hinged through the torsion springs 11. The end of the frame 2 connected to the base 1 is spaced apart from the edge of the base 1. Therefore, under the action of the torsion springs 11, the four frames 2 are unfolded in a horizontal state. During the unfolding process of the four frames 2 The four sub-target pieces 31 will be unfolded. The sub-target pieces 31 are made of flexible materials such as cloth. After the four sub-target pieces 31 are unfolded, a complete target piece 3 will be formed. Two opposite target pieces are red, and the other two opposite target pieces are white. The base 1 is placed in the center of the surveying and mapping positioning to complete the marking positioning of the remote sensing mapping. When the remote sensing mapping equipment is used and recycled, it is only necessary to fold the four skeletons 2 toward the bottom of the base 1 to overcome the corresponding torsion springs 11, so that the four skeletons 2 are folded up, and the sub-target pieces 31 are folded as the skeletons 2 are folded, and the four skeletons 2 are away from the base One end of the seat 1 has an outward expansion force brought by a torsion spring 11. After the four skeletons 2 are inserted into the circular groove 12, the skeleton 2 is loosened, and the blocks 21 on the two opposite skeletons 2 will be stuck in the slots 13, so that multiple remote sensing mapping devices are connected in series; a single remote sensing mapping device can also be bundled and folded with a rope; the present invention enables the block 21 on one remote sensing mapping device to be stuck in the slot 13 on another remote sensing mapping device after the skeleton 2 is folded, thereby connecting multiple remote sensing mapping devices in series, thereby facilitating the removal and transfer of the remote sensing mapping devices, and meeting the needs of outdoor use.

[0036] Example 2: Shielding grooves 22 are provided on both sides of the frame 2; an arc-shaped shielding plate 23 is slidably connected in the shielding groove 22; the shielding plate 23 is connected to the bottom of the shielding groove 22 via a first spring 24.

[0037] In the process of the four skeletons 2 overcoming the corresponding torsion springs 11 to fold, the sub-target pieces 31 are folded as the skeletons 2 are folded, and the sub-target pieces 31 will be folded to the inner side of the four skeletons 2. The gaps between adjacent skeletons 2 are blocked by the retractable shielding plates 23, thereby protecting the sub-target pieces 31 on the inner side of the four skeletons 2 to prevent the sub-target pieces 31 from being scratched during the transfer of remote sensing mapping equipment. The shielding plates 23 on two adjacent skeletons 2 are in contact with each other, and the shielding plates 23 on the skeletons 2 can be retracted, so that in the process of the two relative skeletons 2 getting closer, the shielding plates 23 can overcome the first spring 24 and retract into the corresponding shielding groove 22, so that the four skeletons 2 can be pinched and brought close together without affecting the skeleton 2 driving the card block 21 to unlock in the card slot 13.

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

[0039] In this embodiment, the extension groove 25 is slidingly and sealedly connected to the extension strip 4; a driving groove 14 is provided inside the base 1; the driving groove 14 is slidingly and sealedly connected to the driving plate 5; the driving plate 5 is provided with a one-way air inlet hole 51 from top to bottom; the lower surface of the driving plate 5 is connected to the lower end surface of the driving groove 14 by a third spring 52; the upper end surface of the driving groove 14 is connected to the bottom of the circular groove 12 by an air vent 15; the lower end surface of the driving groove 14 is connected to the bottom of the extension groove 25 by a one-way air outlet hole 16; the upper surface of the driving plate 5 is fixedly connected to the driving rod 53; the driving rod 53 extends upward through the base 1 to the outside; the driving rod 53 is slidingly and sealedly connected to the base 1.

[0040] In this embodiment, a pressure relief groove 26 is provided on the outer wall of the skeleton 2; a pressure relief block 6 is connected to the sliding seal inside the pressure relief groove 26; the pressure relief block 6 is connected to the bottom of the pressure relief groove 26 by a second spring 61; the groove wall of the pressure relief groove 26 and the groove bottom of the extension groove 25 are connected through a first pressure relief hole 27; the outer wall and the inner wall of the pressure relief block 6 are connected to each other and an L-shaped second pressure relief hole 62 is provided; the pressure relief block 6 is squeezed by the base 1, and the second pressure relief hole 62 is staggered with the first pressure relief hole 27; the groove bottom of the extension groove 25 and the extension bar 4 are connected by a first tension spring 41.

[0041] After the skeleton 2 is moved out of the circular groove 12, the skeleton 2 is released and flipped under the torsion of the corresponding torsion spring 11. The four skeletons 2 drive the sub-target pieces 31 to unfold. During the flipping and unfolding process of the skeleton 2, the pressure relief block 6 is driven to press against the lower surface of the base 1. The pressure relief block 6 is squeezed by the base 1 and overcomes the second spring 61 to slide along the pressure relief groove 26. The bottom of the pressure relief groove 26 is through, so the gas in the pressure relief groove 26 is squeezed out during the process of the pressure relief block 6 entering the pressure relief groove 26. After the pressure relief block 6 moves, it drives 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. The driving rod 53 will drive the driving plate 5 to move downward during the downward movement, and the driving plate 5 will separate 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 will enter the extension groove 25 along the one-way air outlet 16. After releasing the driving rod 53, the third spring 52 will drive the driving plate 5 to move upward. During the upward movement of the driving plate 5, the driving rod 53 will be driven upward. During the upward movement of the driving rod 53 and the driving plate 5, the space in the lower cavity will become larger to form a negative pressure. The boundary gas will flow into the lower cavity along the circular groove 12, the air vent 15, the upper cavity and the one-way air inlet 51, thereby replenishing the gas in the lower cavity. As the driving plate 5 moves downward again, the gas in the lower cavity will flow into 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 from the extension groove 25 and extend. After the extension bar 4 extends out of the extension groove 25, the length of the frame 2 is extended, thereby expanding the placement range of the frame 2 on the ground, thereby improving The entire target piece 3 is placed more stably and is less likely to shift, 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 bar 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] Example 4: The side of the extension strip 4 that contacts the ground is provided with a puncture hole 42 ; a puncture rod 43 is slidably and sealedly connected in the puncture hole 42 ; the bottom of the puncture hole 42 is connected to the interior of the extension groove 25 via a diversion hole 44 .

[0043] In this embodiment, the pricking rod 43 is connected to the bottom of the pricking 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 side of the extension bar 4 that contacts the ground; the piercing 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 tying rod 43; the unfolding tilt direction of the 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 of the gas in the driving groove 14 entering 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 the extension bar 4 is pushed by the air pressure, and the puncture rod 43 will move away from the bottom of the puncture hole 42. Due to the obstruction of the embedded plate 47 in the embedded groove 46, the puncture rod 43 will not extend from 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 to move 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 fall off the piercing hole 42. The sliding connection means that it can slide but will not fall off. During the process of the tying rod 43 extending from 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 tilted. As the extension bar 4 As the extension bar 4 continues to move outward, it will drive the lower surface inclined embedded plate 47 away from the base 1. The inclined embedded 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 embedded plate 47 to be inserted into the ground in an outward tilt. In this way, the remote sensing mapping device needs to overcome the resistance of the embedded 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, which makes the force required for the displacement of the remote sensing mapping device greater. In this way, the extension bar 4 can be expanded outward and the embedded plate 47 can be inserted into the ground by repeatedly pressing the driving rod 53 intermittently, thereby improving the remote sensing mapping device. 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 world 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] Example 5: The driving rod 53 is fixedly connected to the pedal plate 7 at one end away from the driving plate 5; the outer wall of the pedal plate 7 is symmetrically provided with two first slots 71 and two second slots 72; the line connecting the two first slots 71 is perpendicular to the line connecting the two second slots 72; the cross-section of the first slot 71 is adapted to the cross-section of the skeleton 2; the depth of the second slot 72 is greater than that of the first slot 71.

[0047] After the two remote sensing mapping devices are folded, the ends of the two skeletons 2 without the block 21 in one of the remote sensing mapping devices are inserted into the first slot 71, and the ends of the two skeletons 2 with the block 21 in the remote sensing mapping device are inserted into the second slot 72. Then, the two skeletons 2 with the block 21 are pinched until the ends of the skeleton 2 are completely entered into the circular groove 12, and then the skeleton 2 is released. Under the torsion of the torsion spring 11, the skeleton 2 drives the block 21 to be clamped into the slot 13, thereby realizing the end-to-end connection of the two independent remote sensing mapping devices. The first slot 71 restricts the other two skeletons 2 without the block 21, so that the ends of the skeleton 2 cannot shift in the circular groove 12, thereby making the connection between adjacent remote sensing mapping devices more stable. An annular rope can be set on the outside of the four skeletons 2, so that the annular rope can be moved around the block 21 during the folding process, so that the folding of a single remote sensing mapping device can be realized independently. When the skeleton 2 is unfolded, the annular sleeve is moved to the lower surface position of the base 1 without hindering the unfolding of the skeleton 2.

[0048] Example 6: The extension strip 4 is composed of a near spring strip 48 and a far spring strip 49; the near spring strip 48 is connected to the first tension spring 41; the far spring strip 49 is rotatably sealed with the near spring strip 48; the diverter hole 44 is eccentrically arranged in the extension strip 4; the puncture hole 42 and the embedding groove 46 are arranged on the far spring strip 49.

[0049] In the case of outdoor fields, it is only necessary to keep the embedding groove 46 facing the ground. At this time, the diverter holes 44 on the near spring bar 48 and the far spring bar 49 are aligned and kept connected, so that the piercing hole 42 is kept connected with the extension groove 25, so that the piercing rod 43 and the embedding plate 47 are driven to realize the insertion of the embedding plate 47 into the ground; when used on hard ground such as urban cement, after the far spring bar 49 is moved out of the extension groove 25, the embedding plate 47 is pinched and pressed against the embedding groove 46, and the far spring bar 49 is rotated so that the diverter hole 44 on the far spring bar 49 is staggered with the diverter hole 44 on the near spring bar 48 until the embedding groove 46 is away from the ground, so that the piercing hole 42 is disconnected from the extension groove 25, so that the embedding plate 47 cannot be moved out of the embedding groove 46, making the surface of the extension bar 4 flat, so that the sub-target piece 31, the skeleton 2 and the extension bar 4 are better attached to the ground, thereby meeting the surveying and mapping marking of different urban and rural terrains.
