Description

Technical Field

[0001] This utility model relates to cameras, specifically to a dual-light camera for evaluating the quality of visible light and infrared image fusion. Background Technology

[0002] With the rapid development of multimodal fusion algorithms, visible light and infrared image fusion technology is widely used in security, remote sensing, and medical fields. The quality of the fused image has a decisive impact on the effectiveness of subsequent analysis and recognition. Therefore, obtaining a high-quality fused image is a crucial step in the entire algorithm process. Capturing and fusing images of a scene from different poses, and then using quality evaluation techniques to select high-quality fused images, is an effective method to solve this problem. As the core component for acquiring dual-band images, the performance of a dual-light camera lays the foundation for the quality of the fused image.

[0003] However, cameras on the market today are usually fixed in place and can only cover a fixed angle range. This greatly limits their field of view and makes it difficult to capture images from multiple angles. Consequently, it is difficult to obtain high-quality fused images, which is a significant shortcoming in practice. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the above-mentioned background technology and provide a dual-light camera for evaluating the quality of visible light and infrared image fusion, which can realize the adjustment of the vertical and horizontal angles of the dual-light camera, and the angle adjustment is precise and stable.

[0005] The technical solution adopted by this utility model to solve its technical problem is a dual-light camera for evaluating the quality of visible light and infrared image fusion, including a device body. The device body includes a dual-light camera body, a horizontal angle adjustment mechanism, and a vertical angle adjustment mechanism. The vertical angle adjustment mechanism includes a U-shaped base, a rotating column, and a motor. The dual-light camera body is located in the U-shaped groove of the U-shaped base. The dual-light camera body is connected to the U-shaped base through the rotating column and rotates around the rotating column as an axis. The motor is externally mounted on the U-shaped base, and the output shaft of the motor is rigidly connected to the connecting column. The horizontal angle adjustment mechanism includes a base, a connecting column, a gear, an electric telescopic rod, and a rack. The base is located below the U-shaped base. The upper end of the connecting column is connected to the U-shaped base, and the lower end is connected to the base. The gear is fixed to the outer surface of the lower end of the connecting column. The electric telescopic rod is installed on the upper surface of the base, and the rack is installed on the electric telescopic rod. The extension and retraction of the electric telescopic rod drives the rack to move linearly, and the rack and gear mesh with each other.

[0006] Furthermore, a guide seat is fixedly installed on the upper surface of the base, and a linear guide mechanism is provided inside the guide seat, which is slidably connected to the rack.

[0007] Furthermore, the base is provided with a fixing mechanism, which includes a clamping plate. The base has a U-shaped structure, and the clamping plate is located in the U-shaped groove of the base. A slot is formed between the clamping plate and the lower side plate of the base.

[0008] Furthermore, the fixing mechanism also includes a threaded rod. The lower side plate of the base is connected to the clamping plate through the threaded rod. The threaded rod is screwed into a pre-set threaded hole in the lower side plate of the base. The top end of the threaded rod is connected to the clamping plate. Rotating the threaded rod can drive the clamping plate to move up and down.

[0009] Furthermore, a handwheel is installed at the bottom end of the threaded rod, which can be rotated to drive the threaded rod to rotate, thereby causing the clamping plate to move up and down.

[0010] Furthermore, the electric telescopic rod is equipped with a travel limit switch.

[0011] Furthermore, protective covers can be detachably installed at both the top and bottom of the dual-light camera body.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] Reference Figure 1-5 The dual-light camera for evaluating the quality of visible light and infrared image fusion in this embodiment includes a device body 100, which includes a dual-light camera body 110, a horizontal angle adjustment mechanism 111, and a vertical angle adjustment mechanism 112.

[0024] The vertical angle adjustment mechanism 112 is used to control the vertical orientation of the dual-light camera body 110. The vertical angle adjustment mechanism 112 includes a U-shaped base 119, a rotating column 120, and a motor 121. The dual-light camera body 110 is located within the U-shaped groove of the U-shaped base 119 and is connected to the U-shaped base 119 via the rotating column 120. The dual-light camera body 110 rotates around the rotating column 120 as its axis. The motor 121 is externally mounted on the U-shaped base 119, and its output shaft is rigidly connected to the connecting column 115. The motor 121 is a high-precision stepper motor with microstepping drive function, enabling precise adjustment of minute angles, with a minimum adjustment accuracy of 1 degree.

[0025] The horizontal angle adjustment mechanism 111 is used to realize the horizontal orientation change of the dual-light camera body 110. The horizontal angle adjustment mechanism 111 includes a base 114, a connecting column 115, a gear 116, an electric telescopic rod 117, and a rack 118. The base 114 is located below the U-shaped base 119, forming a stable underlying support platform. The upper end of the connecting column 115 is connected to the U-shaped base 119, and the lower end is connected to the base 114. The lower end of the connecting column 115 is connected to the base 114 through a bearing, ensuring that the connecting column 115 can rotate flexibly relative to the base 114. The bearing adopts a ball bearing, which has the characteristics of low friction and high load-bearing capacity, ensuring that the connecting column 115 can rotate flexibly and smoothly relative to the base 114. Its structural design has been optimized through mechanical simulation to meet the high strength load-bearing requirements and withstand the stress impact caused by frequent angle adjustment. Gear 116 is fixed to the lower outer surface of connecting column 115; electric telescopic rod 117 is installed on the upper surface of base 114, and rack 118 is installed on electric telescopic rod 117. The telescopic movement of electric telescopic rod 117 drives rack 118 to move linearly. Rack 118 and gear 116 mesh with each other, thereby driving U-shaped base 119 and the dual-light camera body 110 above to achieve horizontal angle adjustment. Gear 116 is made of high-quality alloy steel, precision forged and then machined, with high tooth surface hardness and strong wear resistance. It fits tightly with rack 118, with a transmission efficiency of over 98%. Electric telescopic rod 117 is equipped with a travel limit switch, which can effectively prevent damage to the mechanism due to excessive extension and retraction. Its extension speed can be adjusted as needed by an external controller to adapt to the needs of rapid or fine adjustment in different scenarios.

[0026] The dual-light camera body 110 is a key component for capturing high-quality visible light images. It meticulously integrates a high-resolution image sensor manufactured using cutting-edge semiconductor technology, boasting excellent photoelectric conversion efficiency. This sensor can sensitively capture subtle changes in light, ensuring rich detail and lifelike colors in the acquired visible light images, providing a solid data foundation for subsequent image fusion quality evaluation. The optical lens of the dual-light camera body 110 is made of special optical glass, processed with fine grinding and coating techniques. This not only achieves a light transmittance of over 95%, effectively reducing light loss, but also controls chromatic aberration within a minimal range, resulting in clear, sharp images that faithfully reproduce the captured scene.

[0027] A guide seat 125 is fixedly mounted on the upper surface of the base 114. The guide seat 125 contains a precision linear guide mechanism, which is slidably connected to the rack 118, forming a precise sliding engagement. This mechanism provides accurate guidance for the extension and retraction of the rack 118, ensuring that the rack 118 maintains linear motion during extension and retraction, preventing misalignment that could lead to poor gear meshing and affect adjustment accuracy and equipment lifespan. The guide seat 125 also features a self-lubricating coating made from advanced nano-lubricating materials, reducing the sliding friction resistance of the rack 118 by more than 60%, reducing wear, extending service life, and improving adjustment efficiency.

[0028] The base 114 is provided with a fixing mechanism 113, which includes a threaded rod 123 and a clamping plate 124. The base 114 has a U-shaped structure, and the clamping plate 124 is located in the U-shaped groove of the base 114. A slot 122 is formed between the clamping plate 124 and the lower side plate of the base 114. The lower side plate of the base 114 and the clamping plate 124 are connected by the threaded rod 123. The threaded rod 123 is screwed into the threaded hole of the lower side plate of the base 114 in a threaded manner. The top end of the threaded rod 123 is connected to the clamping plate 124 via a bearing. The bearing ensures that the clamping plate 124 rotates flexibly and can closely fit the surface of the object being clamped. A handwheel for easy manual operation is installed at the bottom of the threaded rod 123. The handwheel is ergonomically designed with an anti-slip texture. Turning the handwheel drives the threaded rod 123 to rotate, causing the clamping plate 124 to move up and down, thereby firmly clamping and fixing the dual-light camera body 110 to a desktop or tablet, meeting temporary or portable installation needs. The contact area between the clamping plate 124 and the dual-light camera body 110 is made of soft rubber to avoid scratching the device surface. The inner wall of the slot 122 is lined with a rubber anti-slip layer to enhance friction with the bearing surface and prevent displacement.

[0029] The dual-light camera body 110 has removable protective covers 126 at both its top and bottom, providing dustproof, splashproof, and impact-resistant protection. The protective covers 126 are injection molded from high-strength engineering plastic and undergo special impact-resistant modification treatment, resulting in excellent dustproof, splashproof, and impact-resistant capabilities, achieving an IP54 protection rating. The installation structure uses a convenient snap-on design with elastic plastic clips for quick and easy installation and removal without the need for additional tools. Simultaneously, the surface of the protective cover 126 features an array of heat dissipation holes. These holes are optimized for fluid dynamics, ensuring protection without compromising the heat dissipation performance of the dual-light camera body, guaranteeing a stable operating environment for internal components and ensuring stable operation over extended periods.

[0030] The working principle of this utility model is as follows:

[0031] The U-shaped base 119 of the vertical angle adjustment mechanism 112 provides stable support for the vertical rotation of the dual-light camera body 110. The rotating column 120 serves as a connecting hub, rotatably mounting the dual-light camera body 110 onto the U-shaped base 119. The drive motor rotates, causing the rotating column 120 to rotate, thereby rotating the dual-light camera body 110 around the rotating column 120 as its axis, thus achieving adjustment of the vertical angle of the dual-light camera 110. The motor 121 uses a high-precision stepper motor with a minimum adjustment accuracy of 1 degree, enabling precise adjustment of minute angles.

[0032] The horizontal angle adjustment mechanism 111 drives the rack 118 to move linearly via the extension and retraction of the electric telescopic rod 117. The rack 118 drives the gear 116 to rotate, thereby rotating the U-shaped base 119 and the dual-light camera body 110 above it, thus achieving the adjustment of the horizontal angle of the dual-light camera 110. The guide seat 125 guides the extension and retraction of the rack 118, ensuring the linear movement of the rack 118, avoiding poor meshing between the gear 116 and the rack 118, improving adjustment accuracy and efficiency, and achieving precise and stable adjustment of the horizontal angle of the dual-light camera 110. The fixing mechanism 113 drives the threaded rod 123 to rotate by rotating the handwheel, causing the clamping plate 124 to move up and down, thereby firmly clamping and fixing the dual-light camera body 110 to a desktop or tablet, meeting temporary or portable installation needs.

[0033] Those skilled in the art can make various modifications and variations to this utility model. If such modifications and variations are within the scope of the claims of this utility model and their equivalents, then such modifications and variations are also within the protection scope of this utility model.

[0034] The contents not described in detail in the specification are prior art known to those skilled in the art.
