Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping instruments, and in particular to a three-dimensional terrain scanner for surveying and mapping. Background Technology

[0002] As a core piece of equipment in the field of surveying and mapping, 3D terrain scanners digitize terrain coordinates by transmitting and receiving detection signals such as lasers and infrared sensors, providing crucial data support for geological exploration, engineering construction, and disaster monitoring. However, in actual field operations, the complexity of terrain (such as depressions, gullies, steep slopes, and sinkholes) often results in areas that the scanner's main field of view cannot directly cover, creating blind spots and data gaps that severely impact the integrity of the 3D model and the reliability of the data.

[0003] Existing technologies have proposed using mirror-assisted scanning. By placing mirrors around the target area, the laser beam is reflected and covers obstructed areas, thereby reducing blind spots and the number of times the equipment needs to be set up. However, because placing independent mirrors in complex terrain requires multiple complex position checks, and after placing the mirrors, it is necessary to return to the scanner to check if the position is suitable, the operation process is cumbersome and easily affected by the field environment, thus reducing the efficiency of terrain scanning. Utility Model Content

[0004] Therefore, it is necessary to provide a 3D terrain scanner for surveying and mapping to address the problem that the operation process is cumbersome and easily affected by the field environment due to the need for multiple complex position checks when additional independent mirrors are set up in complex terrain, which reduces the efficiency of terrain scanning.

[0005] A three-dimensional terrain scanner for surveying and mapping includes: a scanning mechanism, the scanning mechanism including a support frame, a laser scanner and telescopic legs, the laser scanner being rotatably disposed inside the support frame, and the telescopic legs being disposed on the lower surface of the support frame; A reflective mechanism, comprising a mirror, a connecting frame, a movable frame, and a movable plate; The movable frame and the movable plate are each provided in two sets. The two sets of movable frames are set on both sides of the support frame through a connecting frame. The movable plate is slidably set inside the corresponding movable frame. The mirror is rotatably set between the two sets of movable plates through two sets of damping shafts.

[0006] In one embodiment, a limiting plate is provided at the end of the movable plate away from the mirror surface, and both the movable plate and the limiting plate are slidably disposed inside the corresponding movable frame.

[0007] In one embodiment, the movable frame has a movable groove corresponding to the movable plate inside, and the end of the movable frame near the mirror has a limiting groove corresponding to the limiting plate.

[0008] In one embodiment, the movable plate and the limiting plate are slidably disposed inside the corresponding movable frame, and the movable groove is connected to the corresponding limiting groove.

[0009] In one embodiment, spring plungers are provided on both sides of the limiting plate, and positioning holes corresponding to the spring plungers are provided on both sides of the moving frame.

[0010] In one embodiment, a shielding frame is fixedly provided on one side of the support frame, and both the support frame and the shielding frame have shielding grooves corresponding to the mirror surface on their inner sides.

[0011] In one embodiment, the shielding frame has sliding grooves on both sides corresponding to the damping pivot, and the two sets of sliding grooves are connected to the shielding groove.

[0012] In one embodiment, a pull ring is provided on the side of the mirror away from the connecting frame, and the mirror is located above the laser scanner.

[0013] Beneficial effects 1. The aforementioned 3D terrain scanner uses a connecting frame, a moving frame, and a moving plate to set a mirror on the upper surface of the support frame. The mirror rotates between two sets of moving plates via a damping pivot. The moving plates extend and retract within the moving frame, which facilitates the adjustment of the mirror's extension length and rotation angle. This avoids the need to adjust back and forth between the laser scanner and the obstructed area when setting up the mirror, thereby simplifying the operation process and improving the efficiency of terrain scanning.

[0014] 2. The aforementioned 3D terrain scanner has a shielding groove inside the support frame and shielding frame that corresponds to the mirror surface. When the mirror is not in use, it can be stored inside the shielding frame to protect the mirror surface and prevent it from being covered by dust or damaged by foreign objects when it is not in use.

[0018] 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. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined Figures 1-5 This invention describes a three-dimensional terrain scanner for surveying and mapping.

[0020] In one embodiment, a three-dimensional terrain scanner for surveying and mapping includes: a scanning mechanism 100, which includes a support frame 101, a laser scanner 102, and a telescopic leg 103. The laser scanner 102 is rotatably disposed inside the support frame 101, and the telescopic leg 103 is disposed on the lower surface of the support frame 101; and a reflection mechanism 200, which includes a mirror 201, a connecting frame 202, a moving frame 203, and a moving plate 205. Two sets of moving frames 203 and moving plates 205 are provided. The two sets of moving frames 203 are disposed on both sides of the support frame 101 via the connecting frame 202, and the moving plates 205 are slidably disposed inside the corresponding moving frames 203. The mirror 201 is rotatably disposed between the two sets of moving plates 205 via two sets of damping shafts 209. A pull ring 210 is provided on the side of the mirror 201 away from the connecting frame 202, and the mirror 201 is located above the laser scanner 102. In this embodiment, the laser scanner 102 can be a FaroFocus series model; the support frame 101 is a U-shaped frame, and the inner side of the frame is provided with a bearing for mounting the laser scanner 102. The pitch angle of the laser scanner 102 is adjustable to meet the scanning needs of terrains at different heights; and a telescopic leg 103 is provided connected to the lower surface of the support frame 101 to facilitate adjustment of the scanning height of the laser scanner 102. The movable plate 205 is slidably disposed inside the movable frame 203, thereby facilitating adjustment of the extension length of the mirror 201. The mirror 201 is connected to the movable plate 205 through a damping pivot 209, thereby ensuring that the mirror 201 can be adjusted according to the position of the obstructed area, avoiding the need to adjust back and forth between the laser scanner 102 and the obstructed area when setting up the mirror 201, thus simplifying the operation process and improving the efficiency of terrain scanning.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, a limiting plate 206 is provided at the end of the movable plate 205 away from the mirror surface 201. The movable plate 205 and the limiting plate 206 are slidably disposed inside the corresponding movable frame 203. The movable frame 203 has a movable groove 207 corresponding to the movable plate 205 inside, and a limiting groove 208 corresponding to the limiting plate 206 is provided at the end of the movable frame 203 near the mirror surface 201. The movable plate 205 and the limiting plate 206 are slidably disposed inside the corresponding movable frame 203, and the movable groove 207 is connected to the corresponding limiting groove 208. In this embodiment, the size of the limiting plate 206 is larger than that of the moving plate 205. Both the moving plate 205 and the limiting plate 206 slide inside the moving groove 207. The limiting groove 208 is provided to ensure that the moving plate 205 can extend out of the moving frame 203. At the same time, the limiting plate 206 cannot extend out of the moving frame 203 through the limiting groove 208. Thus, the limiting plate 206 prevents the moving plate 205 from leaving the moving frame 203, thereby ensuring the stability of the moving frame 203 and the moving plate 205 when supporting the mirror 201, and also ensuring the stability when adjusting the extension length of the mirror 201.

[0022] like Figure 3 , Figure 4 and Figure 5 As shown, spring plungers 211 are provided on both sides of the limiting plate 206, and positioning holes 212 corresponding to the spring plungers 211 are provided on both sides of the moving frame 203; a shielding frame 204 is fixedly provided on one side of the support frame 101, and shielding grooves corresponding to the mirror surface 201 are provided on the inner sides of both the support frame 101 and the shielding frame 204; sliding grooves corresponding to the damping shaft 209 are provided on both sides of the shielding frame 204, and the two sets of sliding grooves are connected to the shielding grooves; In this embodiment, several sets of positioning holes 212 are provided on the side of the movable frame 203. When the movable plate 205 extends out of the movable frame 203, the spring plunger 211 will engage with the corresponding positioning hole 212, thereby fixing the extension length of the movable plate 205 and preventing the mirror 201 from shaking or shifting during use, ensuring the stability of the mirror 201 during use, and thus ensuring the accuracy of the laser scanner 102 during scanning. Furthermore, when the mirror 201 is not in use, it is stored inside the shielding frame 204 to protect it from dust accumulation or damage from external objects.

[0023] Working principle: When the mirror 201 is not in use, it is stored inside the shielding frame 204 to protect it. When scanning the shielded area is required, the pull ring 210 is operated to pull the mirror 201 out of the shielding frame 204. At this time, the moving plate 205 extends from the moving frame 203, and the spring plunger 211 is engaged in the corresponding positioning hole 212. Then, the extension length and rotation angle of the mirror 201 are adjusted according to the shielded area, so that the mirror 201 can be adjusted next to the laser scanner 102 until the laser scanner 102 can scan the shielded area through the reflection of the mirror 201. This avoids the need to walk back and forth between the laser scanner 102 and the shielded area to adjust the mirror 201 when it is deployed, thus simplifying the operation process and improving the efficiency of terrain scanning.

[0024] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
