Description

Technical Field

[0001] This utility model relates to the field of photogrammetry technology, and more specifically, to a multi-angle photogrammetry device with supplementary lighting function. Background Technology

[0002] Photogrammetry is the process of acquiring images using optical cameras, which are then processed to obtain the shape, size, location, characteristics, and interrelationships of the photographed objects. Its main task is to produce topographic maps of various scales, establish topographic databases, and provide spatial foundation data for various geographic information systems, land information systems, and various engineering applications. It also serves non-topographic fields such as industry, architecture, biology, medicine, and archaeology. In use, existing photogrammetric equipment is usually equipped with supplementary lighting components to meet the needs of photogrammetric work in environments with poor lighting conditions.

[0003] However, there are various types of photogrammetric devices in the existing technology. For example, utility model patent CN210833533U involves a multi-angle photogrammetric device with supplementary lighting function. This utility model includes a measuring base plate, and a measuring mounting plate is rotatably connected to the top of the measuring base plate. The top of the measuring mounting plate is fixedly mounted with a photogrammetric camera body. This utility model has a scientific and reasonable structure and is safe and convenient to use. By setting a fixing screw, telescopic support rod, fixing soft plug, disassembly base and conical foot, the position and distance between the telescopic support rod and the rotating support rod can be adjusted. The telescopic support rod can be stably supported by the conical foot, so that the photogrammetric device can be stably placed. By setting a supplementary light, condenser, diffuser, supplementary lighting mounting base and supplementary lighting placement base, the supplementary light can be operated to provide supplementary lighting for photogrammetry. The condenser or diffuser can be installed at one end of the supplementary light to adjust the supplementary lighting effect of the supplementary light, which is convenient for supplementary lighting during photogrammetry, and the supplementary lighting effect is adjustable.

[0004] Although this measuring device can provide supplementary lighting for photogrammetry in low light conditions and the supplementary lighting effect is adjustable, the structure of the supplementary light inside the device is fixed and the position of the supplementary light cannot be adjusted according to the actual needs of the staff. This results in a limited supplementary lighting range and may affect photogrammetry work due to improper supplementary lighting effect. In order to avoid this phenomenon, it is necessary to design a multi-angle photogrammetry device with supplementary lighting function. Utility Model Content

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0027] like Figure 1 as well as Figure 2 As shown, this is a schematic diagram of the structure of the multi-angle photogrammetry device with supplementary lighting function in this embodiment. The multi-angle photogrammetry device in this embodiment includes a support rod 1, a connecting plate 2 fixedly connected to the top of the support rod 1, a rotating column 3 set on the connecting plate 2 through a bearing, a turntable 4 fixedly connected to the top of the rotating column 3, a camera measuring camera 5 mounted on the top of the turntable 4, a rotation damper 6 set on the top of the camera measuring camera 5, a rotating rod 7 fixedly connected to the top of the rotation damper 6, and a supplementary light 13 mounted above the rotating rod 7. During the process of adjusting the position of the supplementary lighting, the camera measuring camera 5 can rotate under the action of the rotating column 3 to adjust the angle of the camera measurement. After the camera position is adjusted, the direction of the supplementary light 13 can be adjusted by setting the rotation damper 6 and using the rotating rod 7.

[0028] like Figure 3 As shown, in this embodiment, the top of the rotating rod 7 is provided with a mounting base 8, the front of the mounting base 8 is provided with a guide rail 9, a movable frame 10 is slidably mounted on the guide rail 9, a threaded sleeve 14 is provided on the movable frame 10, and a threaded limiting rod 15 is threadedly connected to the inner surface of the threaded sleeve 14. One end of the threaded limiting rod 15 is fixedly connected to an adjusting plate 16, and the adjusting plate 16 is located above the movable frame 10. By utilizing the sliding cooperation between the guide rail 9 and the movable frame 10, the movable frame 10 is slid on the guide rail 9 to move the movable frame 10 to a designated position. Then, the adjusting plate 16 is rotated to drive the threaded limiting rod 15 to rotate. The threaded limiting rod 15 is tightened so that its end is pressed against the guide rail 9. The movable frame 10 is positioned by the threaded limiting rod 15, thereby adjusting the irradiation position of the supplementary light 13 laterally.

[0029] like Figure 4As shown, in this embodiment, a mounting frame 11 is fixedly connected to the top of the movable frame 10. Two drive shafts 12 are arranged inside the mounting frame 11 via bearings. A positioning plate 17 is fixedly connected to the surface of one of the drive shafts 12. The positioning plate 17 has multiple insertion holes, which are evenly spaced. A cylinder 18 is provided on the mounting frame 11. A connecting rod 19 is inserted through the cylinder 18, and one end of the connecting rod 19 can be inserted into the insertion hole. A connecting ring is coaxially provided on the surface of the connecting rod 19. A return spring 20 is provided inside the cylinder 18, and one end of the return spring 20 is fixed to the connecting ring. The connector 19 passes through the return spring 20. The return spring 20 is compressed, and the connector 19 is pulled so that its end is withdrawn from the socket. This releases the fixing effect of the connector 19 on the positioning plate 17, allowing the drive shaft 12 to rotate freely and drive the supplementary light 13 to deflect at an angle. This adjusts the illumination position of the supplementary light 13 longitudinally. After the angle adjustment, the connector 19 is aligned with the corresponding socket. The elasticity of the return spring 20 is used to reset the return spring 20 and push the connecting ring to move, allowing the end of the connector 19 to be reinserted into the corresponding socket to complete the positioning.

[0030] It is worth noting that the supplementary light 13 in the device can be freely adjusted. The staff can adjust the illumination direction and position of the supplementary light 13 according to actual needs, thereby increasing the supplementary lighting range to ensure the supplementary lighting effect and avoid affecting photogrammetry operations.

[0031] like Figure 6 As shown, in this embodiment, a movable sleeve 23 is slidably mounted on the surface of the support rod 1. Multiple support feet 25 are provided on the outer surface of the movable sleeve 23 through the bearing seat 24, and the multiple support feet 25 are distributed at equal intervals. Each support foot 25 is fitted with a plate buckle seat 26. A connecting sleeve 27 is coaxially provided on the surface of the support rod 1. A connecting rod 28 is provided between the connecting sleeve 27 and the multiple plate buckle seats 26 through the bearing seat 24. During the operation of the video measuring camera 5, the multiple plate buckle seats 26 are fixed, and the movable sleeve 23 is slid down. Through the setting of the support feet 25 and the connecting rod 28, and under the linkage of the bearing seat 24, the three support feet 25 are respectively pushed outward. Thus, the three support feet 25 are used to support and fix the entire video measuring device, so that the entire device is stably placed on the ground to facilitate the completion of the video measuring operation.

[0032] It is worth noting that, such as Figure 2 as well as Figure 5 As shown, in this embodiment, the top of the connecting plate 2 is provided with scale lines 21; the surface of the turntable 4 is fixedly connected with a handle 22. By using the handle 22 and rotating the rotating column 3, the turntable 4 is rotated through the handle 22 to adjust the shooting position of the camera measuring camera 5.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
