Description

Technical Field

[0001] This utility model belongs to the field of fire helmet technology, and in particular relates to a parallax-free infrared thermal imaging fire helmet that uses an AR screen display. Background Technology

[0002] Fire helmets are essential equipment for firefighters during firefighting and rescue operations. Fire scenes are complex, filled with smoke and low visibility, and pose a threat of high temperatures. Currently, firefighters mostly rely on handheld infrared thermal imagers for fire scene reconnaissance and heat source location. This method has significant drawbacks: firstly, it occupies the firefighter's hands, affecting their ability to perform key tasks such as demolition and rescue, thus reducing rescue efficiency; secondly, the handheld device needs to be carried separately, increasing the equipment's weight and operational complexity.

[0003] Existing technologies include solutions that integrate infrared modules into helmets. However, the image acquisition modules (infrared cameras and visible light cameras) are typically placed on the top or side of the helmet, creating a significant distance (parallax) between the helmet and the user's eyes. This results in a positional discrepancy between the image captured by the camera and the actual scene observed by the naked eye, requiring firefighters to make additional corrections. This can lead to fatigue and errors in judgment, impacting rescue efficiency in emergencies. Furthermore, the display modules often use external OLED / LCD screens connected to the helmet via flexible, twisted hoses. This method suffers from screen shake, inconvenient viewing, and the hoses being easily snagged by obstacles. Additionally, existing equipment generally lacks effective dual-light (infrared and visible light) fusion capabilities, resulting in low image contour recognition and insufficient protection in extreme high-temperature environments.

[0004] Therefore, there is an urgent need for an integrated infrared thermal imaging fire helmet that can free up hands, eliminate parallax, provide stable display, have image fusion capabilities, and withstand high temperatures. Utility Model Content

[0005] The purpose of this invention is to provide a parallax-free infrared thermal imaging fire helmet with AR screen display to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the specific technical solution of this utility model for a parallax-free infrared thermal imaging fire helmet using an AR screen display is as follows:

[0007] A parallax-free infrared thermal imaging fire helmet with AR display includes a helmet body and functional modules. The functional modules include an image acquisition and display component mounted on the front edge of the helmet body, facing the user's eyes. The image acquisition and display component includes a protective shell, which integrates a binocular AR display screen, a visible light camera, an infrared camera, and an infrared imaging module. The surface of the protective shell has a visible light window and an infrared camera window. The infrared camera window is positioned below and adjacent to the visible light window. The visible light camera is aligned with the visible light window, and the infrared camera is aligned with the infrared camera window. The infrared imaging module is fixedly connected to the infrared camera. The binocular AR display screen is mounted inside the protective shell. The optical centers of the infrared camera and the visible light camera are at the same horizontal level as the user's eyes.

[0008] Furthermore, the image acquisition and display component is mounted on the front edge of the helmet body via a damping pivot, which provides resistance to keep the protective shell stable at any tilt angle.

[0009] Furthermore, the functional modules also include an image and data processing module and a battery module. The image and data processing module and the battery module are fastened to the rear or side of the helmet body by a fixing strap. The battery module is used to power the entire device.

[0010] Furthermore, the binocular AR display screen, visible light camera, infrared camera, and infrared imaging module are connected to the image and data processing module via built-in connecting cables for power and signal transmission.

[0011] Furthermore, the image and data processing module has a built-in wireless transmission module and a Beidou positioning module. The image and data processing module is used to process the data collected by the visible light camera and the infrared camera, perform fusion processing on the infrared image and the visible light image, and transmit it to the remote control platform, and obtain the location of the firefighters through Beidou positioning.

[0012] Furthermore, the wireless transmission module is a WiFi and 4G wireless transmission module.

[0013] Furthermore, the protective shell, the outer shell of the image and data processing module, and the outer shell of the battery module are all made of fireproof, flame-retardant, high-temperature resistant, and acid and alkali resistant materials, and all adopt a double-wall structure, with a vacuum insulation layer formed between the double walls.

[0014] The parallax-free infrared thermal imaging fire helmet using AR screen display of this utility model has the following advantages:

[0015] 1. Parallax-free observation: Both image acquisition (camera) and image display (AR screen) are located on the same horizontal line directly in front of the human eye, realizing "what you see is what you capture", eliminating perspective deviation, making it intuitive and fast, and reducing the cognitive load of firefighters.

[0016] 2. Free your hands: All functions are integrated into the helmet, allowing firefighters to perform rescue operations with both hands free, greatly improving work efficiency and safety.

[0017] 3. Easy to use: The integrated protective shell can be easily flipped up and folded away via a damped hinge, completely avoiding the field of view when the thermal imaging function is not needed, without affecting normal observation.

[0018] 4. Clear images: It has the function of dual light fusion of infrared and visible light, which can highlight the edge contour of heat source targets, improving image recognition and scene understanding capabilities.

[0019] 5. Information sharing: It integrates wireless transmission and Beidou positioning functions, which can realize real-time transmission of on-site images and accurate positioning of personnel, facilitating remote monitoring and dispatching by the command center.

[0020] 6. High environmental adaptability: The key modules adopt a double-layer vacuum heat insulation protection design to ensure the reliability and durability of the equipment in the extreme high temperature environment of the fire scene.

[0021] 7. Stable and safe structure: The display screen is built-in, with no exposed hoses or other parts that are easy to snag. The overall structure is compact and more suitable for use in complex and narrow fire environments. Attached Figure Description

[0026] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a parallax-free infrared thermal imaging fire helmet using an AR screen display.

[0027] like Figure 1 As shown, this utility model discloses a parallax-free infrared thermal imaging fire helmet with AR screen display, comprising a fire helmet body 1 and functional modules. The functional modules include an image acquisition and display component, an image and data processing module 8, and a battery module 9. The image acquisition and display component is mounted on the front edge of the helmet body 1 via a damping hinge 5, facing the user's eyes. The damping hinge 5 provides a certain resistance, allowing the protective shell 4 to remain stably stationary at any tilt angle, such as the horizontal use position or the folded-up position.

[0028] like Figure 2 As shown, the image acquisition and display component includes a protective housing 4, which integrates a binocular AR display 10, a visible light camera 11, an infrared camera 12, and an infrared imaging module 13. The surface of the protective housing 4 has a visible light window 2 and an infrared camera window 3, with the infrared camera window 3 positioned below and adjacent to the visible light window 2. The visible light camera 11 is aligned with the visible light window 2, and the infrared camera 12 is aligned with the infrared camera window 3. The infrared imaging module 13 is fixedly connected to the infrared camera 12, and the binocular AR display 10 is mounted inside the protective housing 4. The optical centers of the infrared camera 12 and the visible light camera 11 are at the same horizontal level as the user's eyes. The mounting positions of the visible light camera 11, the infrared camera 12, and the binocular AR display 10 are precisely designed to ensure that their optical axes are as parallel and close as possible to the wearer's line of sight, achieving parallax-free operation.

[0029] The image and data processing module 8 and the battery module 9 are securely fastened to the rear or side of the helmet body 1 via fixing straps 6 to balance the weight. The binocular AR display 10, visible light camera 11, infrared camera 12, and infrared imaging module 13 are connected to the image and data processing module 8 via built-in connecting cables 7 for power and signal transmission. The battery module 9 powers the entire device. The image and data processing module 8 incorporates a wireless transmission module and a BeiDou positioning module; the wireless transmission module supports both WiFi and 4G wireless transmission. The image and data processing module 8 processes data collected by the visible light camera 11 and the infrared camera 12, fuses the infrared and visible light images, and transmits the data to a remote control platform. BeiDou positioning is used to determine the firefighter's location, facilitating timely rescue measures.

[0030] like Figure 3As shown, the protective shell 4, the shell of the image and data processing module 8, and the shell of the battery module 9 are all made of fireproof, flame-retardant, high-temperature resistant, and acid and alkali resistant materials, and all adopt a double-wall structure 14. A vacuum insulation layer 15 is formed between the double walls, which effectively blocks the external high temperature from being conducted to the inside, ensuring that the core electronic components can still work normally in an environment of 260℃.

[0031] During operation, firefighters wear helmets when entering the fire scene. For thermal imaging observation, the image acquisition and display components are flipped down to face the firefighter. The binocular AR display screen 10 projects the infrared / visible light superimposed image, processed by the image and data processing module 8, onto the firefighter's eyes, allowing them to clearly see the real environment and perceive the distribution and outline of heat sources. Image and location information can be transmitted back to the command center in real time. When not in use, the protective shell 4 can be flipped upwards.
