Description

Technical Field

[0001] This invention relates to the field of optical detection, and in particular to a dynamic multi-view imaging system. Background Technology

[0002] Multi-view imaging technology plays a significant role in fields such as stereo imaging, visual measurement, and 3D reconstruction. The flexible and free adjustment of the number and angle of viewpoints has always been a crucial research topic in multi-view imaging technology.

[0003] In existing technologies, multi-view imaging technology usually utilizes a combination of a bisecting prism or a trisecting prism with a camera to achieve multi-view imaging. For example, Chinese patent CN116466472A discloses a single-detector multi-view compound eye optical imaging system, as well as existing technologies such as "Prism position estimation of monocular stereo vision system [J]. Journal of Northeastern University (Natural Science Edition), 2015, 36(06):765-768" and "Research on stereo image correction based on geometric method [J]. Acta Graphica Sinica, 2014, 35(06):883-888".

[0004] Such existing technologies are limited in the number of viewpoints and visual angles, making it difficult to flexibly change the number of viewpoints and angles according to different imaging or measurement requirements. Summary of the Invention

[0025] In some embodiments, such as Figure 6 As shown, the telescopic adjustment rod assembly 16 includes an outer sleeve 16-1, a telescopic shaft 16-4, and a guide tube 16-6. The telescopic shaft 16-4 is inserted into the outer sleeve 16-1 and slides along the outer sleeve 16-1, forming a cavity between the telescopic shaft 16-4 and the outer sleeve 16-1 arranged along the axial direction of the telescopic shaft 16-4.

[0027] The outer casing 16-1 is hinged to the busbar 15.

[0028] A drive ball 18 is provided inside the annular drive pipe 17. There are two main pipes 13. One end of each main pipe is connected to both ends of the manifold 12, and the other end is connected to the annular drive pipe 17. The connection point with the annular drive pipe 17 is set at an angle of 150 to 180 degrees relative to the center of the annular drive pipe 17.

One end of the swing arm 11-9 is inserted into the swing arm adjustment unit, and the other end is connected to the rear end face of the mounting plate 11-6. The angle of the swing arm 11-9 is changed by the swing arm adjustment unit to adjust the angle of the detector 11-5.

[0033] like Figure 5 As shown, the rocker arm adjustment unit includes a sleeve 11-10 and multiple diaphragm chambers 11-11 disposed within the sleeve 11-10. After the rocker arm 11-9 is inserted into the sleeve 11-10, it is surrounded by the multiple diaphragm chambers 11-11. The diaphragm chambers 11-11 are connected to the manifold 12 through the throttle valve 11-12. The angle of the rocker arm 11-9 is adjusted by adjusting the volume of the fluid medium in each diaphragm chamber 11-11.

[0034] Furthermore, in some embodiments, such as Figure 1 As shown, the fluid supply unit includes: Pump 1 provides the main power source; The first overflow valve 2 and the main solenoid valve 5 are connected to the pump 1 via pipe 1 6. The main solenoid valve 5 is connected to one end of the manifold 12 via pipe 3 8 and to the other end of the manifold 12 via pipe 2 7. The flowing medium passes through the main solenoid valve 5, pipe 3 8, manifold 12, first main pipe 13, annular drive pipe 17, second main pipe 13, manifold 12, pipe 2 7, solenoid valve 5 and oil tank in sequence from the pump 1 to form a circulation loop. The flow direction of the flowing medium can be switched by the solenoid valve 5. Second relief valve 3, third relief valve 4 The second overflow valve 3 and the third overflow valve 4 are connected by pipe 19. The second overflow valve 3 is connected to the manifold 15, and the third overflow valve 4 is connected to the transparent membrane 14.

[0035] In some embodiments, the driving medium of pump 1 is either a transparent liquid or a transparent gas whose refractive index is not equal to that of air.

[0036] Detector 11-5 is an optical transmitter or optical receiver, wherein the optical transmitter includes a searchlight and a laser, and the optical receiver includes a camera, etc.

[0037] How this application works: Pump 1 provides driving medium to manifold 12 and manifold block 15. Multiple telescopic adjustment rod assemblies 16 and annular drive pipe 17 form a polygonal frame. A transparent film bag 14 is placed inside the polygonal frame. The flow direction of the medium in manifold 12 is adjusted by the main solenoid valve 5, and the pressure of the medium in the transparent film bag 14 is kept constant by the first overflow valve 2, the second overflow valve 3, and the third overflow valve 4. The driving ball 18 can circulate and roll in the annular drive pipe 17 with the medium output by pump 1, and the rolling direction of the driving ball 18 is adjusted according to the flow direction of the medium. The telescopic adjustment rod assembly 16 attracts a certain driving ball 18 through electromagnets 16-9. The driving ball 18 drives the telescopic adjustment rod assembly 16 to slide on the annular drive pipe 17. Multiple telescopic adjustment rod assemblies 16 and annular drive pipe 17 form a polygonal frame with different combinations of surface numbers. The transparent film bag 14 placed inside the polygonal frame is filled with medium, thus forming a deformable prism. In addition, the tilt angle of the outer surface of the deformable prism can be further adjusted by the extension and retraction of the telescopic adjustment rod assembly 16. The detector component 11, combined with the deformable prism, enables dynamic multi-viewpoint imaging.

[0038] The working principle of the detection component 11 is as follows: The spatial universal structure formed by the first bracket 11-1, the first bearing 11-2, the first rotating shaft 11-3, the second bracket 11-4, the mounting plate 11-6, the second rotating shaft 11-7, and the second bearing 11-8 allows the detector 11-5 to be in a free state in space. The swing arm 11-9 is wrapped by at least three diaphragm cavities 11-11. By adjusting the pressure in the diaphragm cavity 11-11 through the throttle valve, the expansion degree of each diaphragm cavity 11-11 can be controlled, thereby adjusting the swing angle of the swing arm 11-9, and finally realizing the spatial pose adjustment of the detector 11-5.
