Description

Technical Field

[0001] This utility model relates to the field of three-dimensional laser scanning technology, and in particular to a high-precision three-dimensional laser scanning and mapping device. Background Technology

[0002] 3D laser scanning is a non-contact measurement technology based on the principle of laser ranging. By employing advanced laser emission and reception technology, a high-precision angle measurement system, and precise data processing algorithms, it can effectively reduce measurement errors and provide high-precision 3D data. As an important auxiliary tool in 3D laser scanning mapping, the performance of the target directly affects the accuracy and quality of the scanning data.

[0003] Currently, the targets used in 3D laser scanning mapping are mostly composed of two parts: the target plate and the support frame. In order to facilitate carrying and storage after use, the support frame is usually assembled with bolts. When carrying and storing, the connecting parts of the support frame must be disassembled one by one, which is cumbersome. Moreover, the target plate is also prone to dust accumulation when used outdoors. In order to avoid affecting the scanning accuracy, the target plate needs to be wiped and cleaned manually frequently. Summary of the Invention

[0004] This invention provides a high-precision three-dimensional laser scanning and mapping device, which eliminates the need to disassemble bolts when unfolding and folding the target plate, making it more convenient to carry and store. Furthermore, it eliminates the need for manual cleaning of the target plate, making it more convenient to use.

[0005] In a first aspect, this utility model provides a high-precision three-dimensional laser scanning and mapping device, specifically comprising: a main housing; a cleaning brush fixed on the inner walls of the front and rear sides of the main housing; a support leg storage groove on the left and right sides of the main housing; two target plate fixing rods slidably installed on the inner side of the main housing, and a target plate fixed between the two target plate fixing rods; a connecting block rotatably connected to the bottom of each of the two target plate fixing rods, and a support leg rotatably connected to the bottom of each connecting block.

[0006] Each of the support legs has a rectangular protrusion on its outer side. When the support leg is rotated to a vertical position and slides upward to the top, the rectangular protrusion on its outer side will be in close contact with the bottom outer wall of the main housing.

[0007] The target plate fixing rod, connecting block and supporting leg are all rectangular in cross-section. The main housing has two vertical holes that run vertically through it, and the cross-sectional dimensions of the vertical holes are equal to the cross-sectional dimensions of the target plate fixing rod, connecting block and supporting leg.

[0008] When the target plate fixing rod, connecting block and support leg are rotated to a vertical position and slide to the top, the target plate will be completely above the main housing, and the connection position of the target plate fixing rod, connecting block and support leg will be located in the vertical hole inside the main housing.

[0009] The main housing has a rectangular groove with a top opening on its inner side. The cleaning brush is located on the front and back sides of the top of the rectangular groove. When the target plate fixing rod slides down to the bottom, the target plate will be completely embedded in the rectangular groove on the inner side of the main housing, and the cleaning brush will be in close contact with the front and back outer walls of the target plate.

[0010] The width of the support leg storage groove is equal to the width of the support leg, and a rubber protrusion is provided at the front and rear inner wall edges of the support leg storage groove.

[0011] When the target plate fixing rod slides down to the bottom and the connecting block rotates to a horizontal position, the connecting block will be in close contact with the bottom surface of the main housing. At this time, the support leg will be rotated upward to a vertical position and then embedded in the support leg storage groove.

[0012] This invention provides a high-precision three-dimensional laser scanning and mapping device, which has the following advantages: The connection positions of the target plate fixing rod, connecting block, and support leg in this utility model can be rotated and adjusted. Moreover, the target plate fixing rod, connecting block, and support leg can also slide up and down in the main housing. When unfolding and folding the target plate, there is no need to disassemble the bolts, making it more convenient to carry and store. In addition, the cleaning brush on the inside of the main housing can clean the dust on the surface of the target plate each time it is folded and unfolded, eliminating the need for manual wiping and cleaning of the target plate, making it more convenient to use.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Example 1: Please refer to Figures 1 to 6 : This invention proposes a high-precision three-dimensional laser scanning and mapping device, comprising: a main housing 1; a cleaning brush 2 fixed on the inner walls of the front and rear sides of the main housing 1, the main housing 1 being used to wrap and protect the target plate 5; when the device is finished and needs to be folded up, the main housing 1 can be pushed upwards, during which the target plate 5 will be embedded in the rectangular groove inside the main housing 1, and the cleaning brush 2 can clean the dust on the front and rear sides of the target plate 5, thus ensuring that the target plate 5 is clean after each use; a support leg storage groove 3 is provided on both the left and right sides of the main housing 1, supporting... The support leg storage groove 3 is used to limit the position of the folded support leg 7; two target plate fixing rods 4 are slidably installed on the inner side of the main housing 1, and a target plate 5 is fixed between the two target plate fixing rods 4. The target plate fixing rods 4 are used to support the target plate 5, and the target plate 5 is used to assist the laser scanner in performing three-dimensional scanning; a connecting block 6 is rotatably connected to the bottom of each of the two target plate fixing rods 4, and a support leg 7 is rotatably connected to the bottom of each connecting block 6. The connecting block 6 is used to connect the target plate fixing rods 4 and the support leg 7, and the support leg 7 is used to support the upper part of the structure of this device.

[0018] In this embodiment, as Figures 1-4 As shown, each of the support legs 7 has a rectangular protrusion on its outer side. When the support leg 7 is rotated to a vertical position and slides upward to the top, the rectangular protrusion on its outer side will be in close contact with the bottom outer wall of the main housing 1, thereby limiting the support leg 7 and preventing the support leg 7 from sliding upward too much.

[0019] In this embodiment, as Figures 1-6As shown, the target plate fixing rod 4, connecting block 6, and support leg 7 all have rectangular cross-sections. The main housing 1 has two vertical holes that extend vertically through it. The cross-sectional dimensions of the vertical holes are equal to those of the target plate fixing rod 4, connecting block 6, and support leg 7. This allows the target plate fixing rod 4, connecting block 6, and support leg 7 to slide up and down in the vertical holes inside the main housing 1. Furthermore, the target plate fixing rod 4, connecting block 6, and support leg 7 cannot rotate when their connection points are located in the vertical holes inside the main housing 1, ensuring the stability of the device after deployment.

[0020] In this embodiment, as Figure 1 and Figure 3 As shown, when the target plate fixing rod 4, connecting block 6 and support leg 7 are rotated to the vertical position and slide upward to the top, the target plate 5 will be completely above the main housing 1. The connection position of the target plate fixing rod 4, connecting block 6 and support leg 7 will be located in the vertical hole inside the main housing 1. Therefore, the connection position of the target plate fixing rod 4, connecting block 6 and support leg 7 cannot rotate, ensuring the overall stability of the device. Moreover, at this time, the target plate 5 will be completely exposed upward, thus assisting the laser scanner in performing three-dimensional scanning.

[0021] In this embodiment, as Figures 1-5 As shown, the main housing 1 has a rectangular groove with a top opening on the inner side. The cleaning brush 2 is located on the front and back sides of the top of the rectangular groove. When the target plate fixing rod 4 slides down to the bottom, the target plate 5 will be completely embedded in the rectangular groove on the inner side of the main housing 1. Moreover, the cleaning brush 2 will be in close contact with the front and back outer walls of the target plate 5. When the device needs to be put away after use, the main housing 1 can be pushed upward first. During this process, the target plate 5 will be embedded in the rectangular groove on the inner side of the main housing 1. The cleaning brush 2 can clean the dust on the front and back sides of the target plate 5, so that the target plate 5 can be kept clean after each use.

[0022] In this embodiment, as Figure 2 and Figure 4 As shown, after the target plate fixing rod 4 slides down to the bottom and the connecting block 6 rotates horizontally, the connecting block 6 will be in close contact with the bottom surface of the main housing 1. At this time, the support leg 7 will rotate upward to a vertical position and then be embedded in the support leg storage groove 3. When the device needs to be folded up after use, the main housing 1 can be pushed upward first, and then the connecting block 6 can be rotated to a horizontal position. At this time, the connecting block 6 can restrict the target plate fixing rod 4 from sliding upward, thereby locking the position of the target plate 5. Finally, the support leg 7 is rotated upward to a vertical position and forcefully embedded into the support leg storage groove 3, thereby fixing the position of the support leg 7, thus completing the folding process for easy carrying and storage.

[0023] Example 2, based on Example 1, such as Figures 1-6As shown, the width of the support leg storage groove 3 is equal to the width of the support leg 7. Moreover, a rubber protrusion strip is provided on the front and rear inner wall edges of the support leg storage groove 3. When the device needs to be folded up after use, the main housing 1 can be pushed upward first, then the connecting block 6 can be rotated to a horizontal state, and finally the support leg 7 can be rotated upward to a vertical state and forcefully embedded into the support leg storage groove 3. At this time, the rubber protrusion strip on the inner wall of the support leg storage groove 3 can lock the support leg 7, thereby fixing the position of the support leg 7.

[0024] The working principle of this embodiment is as follows: When using this device for 3D laser scanning and mapping, first rotate the connecting block 6 and the support leg 7 to a vertical position, and then forcefully push the connecting block 6 and the support leg 7 upwards at the bottom of the main housing 1. During this process, the tops of the connecting block 6 and the support leg 7 will be embedded in the vertical holes inside the main housing 1 until the rectangular protrusion on the outer side of the support leg 7 is in close contact with the bottom outer wall of the main housing 1, thereby limiting the support leg 7 and preventing it from sliding upwards too much. At this time, the connection position of the target plate fixing rod 4, the connecting block 6, and the support leg 7 will be located in the vertical holes inside the main housing 1. Therefore, the connection position of the target plate fixing rod 4, the connecting block 6, and the support leg 7 cannot be rotated, ensuring the overall stability of the device. Moreover, at this time, the target plate 5 will be fully exposed upwards, and then the device can be... The support leg 7 is stably placed on the ground, allowing the target plate 5 to assist the laser scanner in 3D scanning. When the device is finished and needs to be folded up, the main housing 1 can be pushed upwards first. During this process, the target plate 5 will be embedded in the rectangular groove inside the main housing 1. The cleaning brush 2 can clean the dust on the front and back sides of the target plate 5, ensuring that the target plate 5 is clean after each use. Then, the connecting block 6 is rotated to a horizontal position. At this time, the connecting block 6 can restrict the upward sliding of the target plate fixing rod 4, thereby locking the position of the target plate 5. Finally, the support leg 7 is rotated upwards to a vertical position and forcefully embedded into the support leg storage groove 3. At this time, the rubber protrusion strip on the inner wall of the support leg storage groove 3 can clamp the support leg 7, thereby fixing the position of the support leg 7, thus completing the folding, making it easy to carry and store.

[0026] 2. Where there is no conflict, this embodiment and the features in the embodiment can be combined with each other to obtain new embodiments.
