Summary of the Invention

[0013] To address the technical problems existing in related technologies, this application provides a safety protection system for unmanned excavators. Please refer to [link / reference]. Figure 1 , Figure 1 This is a schematic diagram of a fiber optic side-view imaging structure provided in an embodiment of this application. The fiber optic side-view imaging structure includes: a left fiber, a right fiber, an X-direction light source, a Y-direction light source, an X-direction camera, a Y-direction camera, an X-direction lens, a Y-direction lens, an X-direction reflector, and a Y-direction reflector. The left fiber and the right fiber are placed opposite each other on both sides of the fiber coupling point sectional plane, and the X-direction light source and the Y-direction fiber are disposed on the fiber coupling point sectional plane. The X-direction optical path formed by the X-direction light source and the Y-direction optical path formed by the Y-direction light source intersect at the fiber coupling point sectional plane to form the fiber coupling point. The X-direction optical path is reflected by the X-direction reflector into the X-direction lens, forming an X-side image of the left fiber on the X-direction camera. The Y-direction optical path is reflected by the Y-direction reflector into the Y-direction lens, forming a Y-side image of the right fiber on the Y-direction camera.

[0014] In one embodiment, the provided fiber optic side imaging structure has a light source, a lens, and a camera respectively set on the left and right sides of the cross-section of the fiber coupling point. The light path formed by the light emitted by the light source is reflected by the set reflector so as to reflect the fiber optic image after the light source passes through the fiber into the lens, and then display the side image of the fiber in the camera.

[0015] For example, the light sources arranged on both sides of the cross-section of the fiber coupling point include an X-direction light source and a Y-direction light source, and the lenses include an X-direction lens and a Y-direction lens, the cameras include an X-direction camera and a Y-direction camera, and the reflectors include an X-direction reflector and a Y-direction reflector. Then, during imaging, the X-direction light path emitted by the X-direction light source passes through the left fiber and is reflected into the X-direction lens by the X-direction reflector, thereby displaying the X-side image of the fiber in the X-direction camera. Similarly, during imaging, the Y-direction light path emitted by the Y-direction light source passes through the right fiber and is reflected into the Y-direction lens by the Y-direction reflector, thereby displaying the Y-side image of the fiber in the Y-direction camera.

[0016] Meanwhile, a portion of the X-axis optical path formed by the X-axis light source and a portion of the Y-axis optical path formed by the Y-axis light source are located on the tangent plane of the fiber coupling point, and the X-axis optical path and the Y-axis optical path intersect to form the fiber coupling point.

[0017] Furthermore, the X-direction optical path formed by the X-direction light source is perpendicular to the left optical fiber, and the Y-direction optical path formed by the Y-direction light source is perpendicular to the right optical fiber.

[0018] Furthermore, the X-axis lens and the Y-axis lens are oriented in the same direction and are parallel to the tangent plane of the fiber coupling point.

[0019] Furthermore, based on the orientation of the X-axis and Y-axis lenses, in order to allow the light emitted from the X-axis and Y-axis light sources to enter the X-axis and Y-axis lenses respectively, a certain number of reflectors can be set in the X-axis and Y-axis optical paths respectively. Specifically, the X-axis reflector includes an X-axis first reflector and an X-axis second reflector, and the Y-axis reflector includes a Y-axis first reflector and a Y-axis second reflector. Thus, the direction of the light path after the action of the X-axis first reflector and the X-axis second reflector is consistent with the direction of the light path after the action of the Y-axis first reflector and the Y-axis second reflector, so as to accommodate the X-axis and Y-axis lenses with the same orientation.

[0020] Specifically, when the X-direction light source is reflected, it passes sequentially through the first X-direction reflector and the second X-image reflector to enter the X-direction lens, thus displaying the X-side image in the X-direction camera. Simultaneously, when the Y-direction light source is reflected, it passes sequentially through the first Y-direction reflector and the second Y-direction reflector to enter the Y-direction lens, thus displaying the Y-side image in the Y-direction camera. The resulting X-side and Y-side images can be applied based on practical needs. For example, in scenarios where lasers are used for fiber optic splicing, the light coupling point can be adjusted based on the analysis and processing of the X-side and Y-side images.

[0021] For example, in the fiber optic side imaging structure, the positions of the first X-axis reflector and the second X-axis reflector in the X-axis reflector and the positions of the first Y-axis reflector and the second Y-axis reflector in the Y-axis reflector can be set, and it is necessary to ensure that after the action of the X-axis reflector and the Y-axis reflector, the X-axis optical path enters the X-axis lens and the Y-axis optical path enters the Y-axis lens.

[0022] For example, the plane formed by the X-direction light source, the X-direction first reflector, and the X-image second reflector is called the first plane, and the plane formed by the Y-direction light source, the Y-direction first reflector, and the Y-direction second reflector is called the second plane. When setting the positions of the X-direction first reflector, the X-direction second reflector, the Y-direction first reflector, and the Y-direction second reflector, the first plane and the second plane can be kept parallel. At the same time, the distance between the X-direction light source and the X-direction first reflector is the same as the distance between the Y-direction light source and the Y-direction first reflector, and the distance is greater than 50 mm. The distance between the X-direction first reflector and the X-direction second reflector is the same as the distance between the Y-direction first reflector and the Y-direction second reflector.

[0023] It should be noted that, in addition to the above-mentioned method, there are other ways to set the positions of the X-direction first reflector, X-direction second reflector, Y-direction first reflector, and Y-direction second reflector. As long as the orientation of the X-direction light path after reflection by the X-direction light source through the X-direction second reflector is consistent with that of the Y-direction light path after reflection by the Y-direction light source through the Y-direction second reflector, it is sufficient to ensure that the orientation of the X-direction light path is consistent with that of the Y-direction light path after reflection by the Y-direction second reflector.

[0024] Furthermore, in order to improve the imaging effect and reduce the influence of the external environment on the imaging, the light-side imaging structure also includes an X-axis protective mirror and a Y-axis protective mirror. The X-axis protective mirror is set in the X-axis optical path and between the X-axis light source and the X-axis first reflector. The Y-axis protective mirror is set in the Y-axis optical path and between the Y-axis light source and the Y-axis first reflector.

[0025] For example, the protective mirror is used to filter light, specifically for lasers. That is, the laser light is filtered out when it passes through the protective mirror, and only the light formed by the X-axis light source and the Y-axis light source is allowed to pass through.

[0026] Furthermore, both the X-axis and Y-axis light sources used are set to red light sources.

[0027] Furthermore, for the X-direction light source and the Y-direction light source, they can be set as divergent light sources, and the divergence angle can be any angle between 0 and 15°.

[0028] Furthermore, the X-axis and Y-axis protective mirrors used are designed to allow visible light wavelengths to pass through, but not laser wavelengths of 10.6 μm.

[0029] Furthermore, the X-axis and Y-axis reflectors are designed to reflect more than 99.5% of visible light.

[0030] Furthermore, both the X-axis and Y-axis lenses are telecentric magnifying lenses, and the magnification can be designed to be between 3 and 8 times depending on the usage requirements.

[0031] Furthermore, both the X-axis and Y-axis cameras are ordinary industrial monochrome cameras. The camera detector target surface matching lens can be matched with a target surface (slightly larger). The camera resolution is designed to be between 5 million and 20 million depending on the usage requirements.

[0032] In summary, this application discloses a fiber optic side-view imaging structure, comprising: a left fiber, a right fiber, an X-axis light source, a Y-axis light source, an X-axis camera, a Y-axis camera, an X-axis lens, a Y-axis lens, an X-axis reflector, and a Y-axis reflector. The left and right fibers are placed opposite each other on opposite sides of the fiber coupling point sectional plane, and the X-axis light source and the Y-axis fiber are positioned on the fiber coupling point sectional plane. The X-axis light path formed by the X-axis light source is reflected by the X-axis reflector into the X-axis lens and displays an X-side image in the X-axis camera; similarly, the Y-axis light path formed by the Y-axis light source is reflected by the Y-axis reflector into the Y-axis lens and displays a Y-side image in the Y-axis camera. This provides a more reasonable layout for the imaging structure, avoiding interference between the fiber optic imaging path and the laser path, and ensuring that fiber optic imaging is unaffected.
