[0044] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0045] Tunnel lighting refers to the lighting system installed inside the tunnel to ensure traffic safety, improve visibility and enhance driver comfort. In the prior art, mining lamps are used to provide lighting. The mining lamps are installed on the top of the tunnel to illuminate the inside of the tunnel. Installing mining lamps on the top of the tunnel is costly, and the light of the mining lamps will produce glare, affecting the visual comfort of the driver.

[0046] Due to the space limitations inside the tunnel and the changes in external light, the existing mining lamp illumination method cannot completely solve the lighting problem in the tunnel, especially in some complex tunnel environments. The light of the mining lamp may not cover all areas, resulting in insufficient light in some areas or glare due to light design defects, which reduces the lighting effect and affects the visual comfort of the human eye.

[0047] Based on this, the embodiments of the present application provide a tunnel lighting method, a tunnel lighting system and a tunnel, which ensure that the lighting effect in the tunnel can meet the visual comfort requirements of the driver and passengers and improve the lighting effect.

[0048] The tunnel lighting method, tunnel lighting system and tunnel provided in the embodiments of the present application are specifically described through the following embodiments.

The network 104 is used to provide a medium for communication links between the terminal devices 101, 102, 103 and the server 105. The network 104 may include various connection types, such as wired, wireless communication links or optical fiber cables, etc.

[0050] Users can use terminal devices 101, 102, 103 to interact with server 105 through network 104 to receive or send messages, etc. Various communication client applications can be installed on terminal devices 101, 102, 103, such as web browser applications, shopping applications, search applications, instant messaging tools, email clients, social online platform software, etc.

[0051] Terminal devices 101, 102, 103 can be various electronic devices with display screens and supporting web browsing, including but not limited to smart phones, tablet computers, e-book readers, MP3 players (Moving Picture Experts Group Audio Layer III), MP4 (Moving Picture Experts Group Audio Layer IV) players, laptop computers, desktop computers, etc.

[0052] The server 105 may be a server that provides various services, such as a background server that provides support for web pages displayed on the terminal devices 101 , 102 , and 103 .

[0053] It should be noted that, optionally, the tunnel lighting method provided in the embodiment of the present application can be executed by a server / terminal device, and accordingly, the tunnel lighting method is generally set in the server / terminal device.

[0054] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is only for illustration. According to the implementation requirements, there may be any number of terminal devices, networks and servers, or the tunnel lighting system may be composed of any number of terminal devices, networks and servers.

[0055] refer to Figure 2 , shows a flow chart of an embodiment of the tunnel lighting method proposed in the present application.

[0056] It should be noted that the tunnel lighting method provided by the embodiment of the present invention is applied to the tunnel. Through the visual simulation technology, the visual adaptation process in the tunnel environment is calculated, and the response characteristics of the human eye in bright vision, dark vision and intermediate vision under different lighting conditions are analyzed, which is helpful to improve the accuracy and rationality of the lighting design, thereby improving the lighting effect and visual comfort. By arranging the mining lamp illumination in the current tunnel, the installation position and number of the mining lamps can be optimized, the cost can be reduced, and the influence of glare can be reduced, and the visual comfort can be further improved. The tunnel can be an urban traffic tunnel to improve the visibility and comfort of the driver inside the tunnel; it can also be a highway tunnel. The highway tunnel is usually longer and the lighting requirements are more stringent. The present invention ensures the continuity and uniformity of the lighting inside the long tunnel by optimizing the lighting design, and improves driving safety; it can also be a mountain tunnel. Mountain tunnels are often accompanied by complex terrain and climate changes. The present invention can adapt to the lighting changes caused by terrain and climate by simulating the visual adaptation process of the human eye under different lighting conditions, provide stable and reliable lighting, and reduce visual discomfort caused by environmental changes.

[0057] It should be understood that the tunnel lighting method provided by the embodiment of the present invention can also be applied in other scenarios, which are not specifically limited here. For example, in the scenario of autonomous driving, by accurately simulating the visual adaptation process of the human eye under different lighting conditions, the environmental perception and decision-making capabilities of the autonomous driving system can be improved, thereby improving driving safety.

[0058] See also Figure 2 ,like Figure 2 As shown, the tunnel lighting method provided by the embodiment of the present invention includes the following steps:

[0059] S210, modeling the environment in the tunnel based on visual simulation technology to obtain a virtual tunnel environment model.

[0060] Optionally, actual geometric data of the tunnel, including the length, width, height and internal structure of the tunnel, are obtained through field measurements or based on existing design drawings, and then an initial three-dimensional geometric model of the tunnel is established using computer-aided design (CAD) software based on the obtained tunnel geometric data.

[0061] Optionally, visual simulation technology refers to the use of computer graphics and image processing technology to simulate and reproduce the visual experience of the human eye in a specific environment. Based on visual simulation technology, the real environmental conditions of the tunnel are simulated in a three-dimensional geometric model, such as setting the natural lighting conditions at the entrance and exit of the tunnel, and simulating different natural light intensities according to time and weather conditions; setting artificial lighting sources inside the tunnel, including main lighting fixtures and auxiliary mining lamps, simulating different lamp layouts, light intensity distribution and light color characteristics; setting different reflectivities and materials for the tunnel road surface to simulate the reflection and absorption of light by the real road; and comprehensively simulating the above-mentioned various environmental factors in a three-dimensional virtual tunnel environment to obtain a virtual tunnel environment model that can truly reproduce the lighting distribution and visual perception state in the tunnel.

[0062] S220, simulating a visual adaptation process of a human eye under lighting conditions in a virtual tunnel environment model, and obtaining visual response characteristics of the human eye under lighting conditions.

[0063] It should be understood that the visual adaptation process refers to the process in which the human eye changes its physiological mechanisms such as pupil size, cone and rod sensitivity to adapt to the ambient brightness under different light intensities. Visual response characteristics refer to the visual perception and physiological response of the human eye to different wavelengths, intensities, distributions and other lighting conditions during the adaptation process, such as visual comfort and resolution.

[0064] Optionally, a physiological vision model is established to simulate the physical and physiological response process of the human eye to light, such as pupil adjustment, cone and rod activation, etc., and then the physiological vision model is integrated into the virtual tunnel environment model so that it can simulate the adaptation state of the real human eye visual system in the environment, set different entrance brightness, tunnel internal lighting and other lighting conditions, and simulate the dynamic process of visual adaptation from bright vision to dark vision and then to intermediate vision. During the adaptation process, the visual response data of the human eye to different light sources, light intensity distribution, light color and other factors, including visual comfort score, contrast resolution, etc., are collected and recorded in real time, and the collected data are analyzed and modeled to obtain a quantitative visual response curve or response function to describe the visual response characteristics of the human eye under various lighting conditions.

[0065] S230: Determine lighting design parameters of the tunnel according to the visual response characteristics.

[0066] It should be understood that lighting design parameters are key parameters that affect tunnel lighting effects and visual comfort, mainly including light source type, light intensity distribution and light color. Light source refers to a light-emitting device that produces visible light, such as LED lamps, fluorescent lamps, etc. Light intensity distribution refers to the intensity distribution of light in space. Light color refers to the wavelength distribution characteristics of light, which can be described by indicators such as correlated color temperature and color rendering index.

[0067] Optionally, by analyzing the visual response characteristics of the human eye, the effects of different light source types, light intensity distribution, and light color on visual comfort, recognition ability, etc. are studied. According to the visual response requirements for the spectrum, the appropriate light source type is selected, and other parameters of the light source such as power, life, energy efficiency ratio and other practical indicators are evaluated.

[0068] Optionally, the requirements of the human eye for light intensity gradient and uniformity can be analyzed based on visual response characteristics, and a light intensity distribution curve along the length of the tunnel can be designed, or lighting facilities can be arranged to achieve an ideal distribution in combination with the tunnel geometry. It is also possible to analyze the excitation efficiency of different light colors on cones or rods, evaluate the visual comfort of various light colors in the light and dark vision and intermediate vision states, and select appropriate light color combinations that can meet various adaptation states.

[0069] S240, optimizing and adjusting the comfort of the mining lamp according to the lighting design parameters, so that the mining lamp provides lighting for the tunnel according to the lighting design parameters.

[0070] It should be understood that a mining lamp refers to a lighting fixture installed on the top or side wall of a tunnel as an auxiliary lighting device. Comfort optimization adjustment is to optimize the layout position, light parameters, etc. of the mining lamp based on the principle of visual comfort to improve the overall lighting effect and visual comfort.

[0071] Optionally, the optimal arrangement position and number of miner's lamps on the top or both sides of the tunnel are determined according to the lighting design parameters, and symmetrical distribution is adopted to ensure that the light from the miner's lamps can cover the entire tunnel, and the luminous intensity, luminous flux and other parameters of the miner's lamps are adjusted to avoid excessive brightness or sudden changes in light intensity in local areas.

[0072] In an embodiment of the present invention, the environment in the tunnel is modeled based on visual simulation technology to obtain a virtual tunnel environment model; in the virtual tunnel environment model, the visual adaptation process of the human eye under lighting conditions is simulated to obtain the visual response characteristics of the human eye under lighting conditions; according to the visual response characteristics, the lighting design parameters of the tunnel are determined; according to the lighting design parameters, the comfort optimization adjustment of the miner's lamp is performed so that the miner's lamp provides lighting for the tunnel according to the lighting design parameters. In an embodiment of the present application, the visual adaptation process in the tunnel environment can be accurately calculated by visual simulation technology, thereby more accurately simulating the visual response characteristics of the human eye under different lighting conditions, ensuring that the lighting effect in the tunnel can meet the visual comfort requirements of the driver and passengers, and improving the lighting effect.

[0073] Optionally, the environment in the tunnel is modeled based on visual simulation technology to obtain a virtual tunnel environment model, including:

[0074] Determine geometric parameters of the tunnel, including tunnel length, tunnel width, tunnel height and tunnel curvature;

[0075] Determine the fixed structural facilities and spatial distribution of fixed structural facilities in the tunnel, and simulate the material properties in the tunnel;

[0076] According to geometric parameters, fixed structural facilities, spatial distribution and material characteristics, modeling is performed based on the human eye vision model to obtain a virtual tunnel environment model.

[0077] In this embodiment, geometric parameters refer to parameters that describe the basic shape and size of the tunnel, including tunnel length, tunnel width, tunnel height and tunnel curvature, etc., which have a direct impact on the lighting distribution and visual effects inside the tunnel. Fixed structural facilities refer to various facilities that are fixed in the tunnel, such as supports, guardrails, traffic signs, lighting equipment, etc. Spatial distribution refers to the relative position and layout of fixed structural facilities inside the tunnel, which will affect the propagation and reflection of light. The material properties of the materials inside the tunnel have certain optical properties, such as reflectivity, transmittance and absorptivity, which have a certain impact on light.

[0078] It should be understood that the environment inside the tunnel is modeled based on visual simulation technology, the human eye's photosensitivity to light is simulated, the tunnel geometry model, facility model, material property model, and visual model are integrated, the precise length, width, height, and curvature of the tunnel are measured and recorded, and the specific spatial distribution of fixed structure facilities in the tunnel is recorded to ensure that the layout in the model is consistent with the actual situation. Through ray tracing, rendering and other technologies, according to the optical properties of the material, the interaction between light and the inner surface of the tunnel, including reflection, refraction and scattering, is simulated, and finally a virtual tunnel environment model is generated. The virtual environment model can truly reproduce the visual effects under tunnel lighting conditions, laying the foundation for subsequent visual response simulation and design parameter optimization.

[0079] Optionally, the lighting conditions include photopic visual conditions, mesopic visual conditions, and scotopic visual conditions. In the virtual tunnel environment model, the visual adaptation process of the human eye under the lighting conditions is simulated to obtain the visual response characteristics of the human eye under the lighting conditions, including:

[0080] Determine lighting conditions based on ambient light information;

[0081] In the virtual tunnel environment model, the visual adaptation process of the human eye under different lighting conditions is simulated to obtain the visual response characteristics of the human eye under different lighting conditions.

[0082] It should be understood that lighting conditions are the state of the light environment that affects human vision, which is mainly divided into three situations: photopic vision, mesopic vision, and scotopic vision. In photopic vision conditions, the ambient brightness is high, and the human eye mainly relies on cones for visual perception. At this time, the human eye is most sensitive to blue light. In mesopic vision conditions, the ambient brightness is between light and dark, and the cones and rods of the human eye work together. In scotopic vision conditions, the ambient brightness is low, and the human eye mainly relies on rods for visual perception. The visual adaptation process is the process in which the physiological indicators of the human eye, such as the sensitivity of photoreceptor cells and pupil size, change to adapt to the new environment when the lighting conditions change.

[0083] It should be understood that a photometer or other measuring tools can be used to collect ambient light information in the tunnel, including brightness, color temperature and light distribution, and based on the collected ambient light information, the lighting conditions inside the tunnel, such as photopic, mesopic or scotopic conditions, can be determined.

[0084] Optionally, during the adaptation process, the visual response indicators such as contrast resolution, brightness perception, and color recognition ability of the human eye are recorded in real time, and the changing patterns and differences of these indicators under different lighting conditions are analyzed. A visual response model can also be established to quantitatively describe the mapping relationship between various visual response characteristics and lighting conditions. Through the above simulation and data collection, the visual response characteristics of the human eye in different adaptation states under the tunnel lighting environment can be fully obtained.

[0085] Optionally, determining the lighting condition according to the ambient light information includes:

[0086] When the light intensity average of the ambient light information is greater than a first preset light intensity threshold, determining that the lighting condition is a photopic vision condition;

[0087] When the light intensity mean value of the ambient light information is less than the first preset light intensity threshold and greater than the second preset light intensity threshold, determining that the lighting condition is a mesopic vision condition, and the first preset light intensity threshold is greater than the second preset light intensity threshold;

[0088] When the light intensity average of the ambient light information is less than the second preset light intensity threshold, it is determined that the lighting condition is a dark vision condition.

[0089] It should be understood that ambient light information refers to a collection of light intensity data at various locations in the environment, reflecting the overall light level. The light intensity mean is the average light intensity value obtained by averaging all light intensity values ​​in the ambient light information. The first preset light intensity threshold and the second preset light intensity threshold refer to two pre-set light intensity critical values, which are used to compare with the light intensity mean to divide different lighting condition ranges.

[0090] Optionally, multiple light intensity measurement points are set in the tunnel environment, and the light intensity value of each measurement point is calculated based on ray tracing and rendering technology, and the light intensity values ​​of all measurement points are collected to form a complete set of ambient light information. By comparing the light intensity mean with the threshold, it is possible to efficiently distinguish which of the three visual adaptation states the current environment belongs to, thereby providing key prerequisite criteria for the subsequent simulation calculation of visual response. The specific values ​​of the first preset light intensity threshold and the second preset light intensity threshold can be adjusted according to actual needs.

[0091] Optionally, according to the visual response characteristics, the lighting design parameters of the tunnel are determined, including:

[0092] Determine the light intensity adaptation process of the human eye under different light intensity changes based on visual response characteristics;

[0093] The light intensity distribution curve is determined according to the light intensity adaptation process and the geometric parameters of the tunnel.

[0094] It should be understood that the light intensity distribution curve refers to the light intensity change curve along the direction of the tunnel, and the change law of visual indicators under different light intensities is extracted from the visual response characteristic data. By establishing a mapping model between visual indicators and light intensity, the light intensity range of the visual comfort zone can be described, and the ideal light intensity range that allows the human eye to obtain a good visual experience can be determined based on the mapping model. Then, based on parameters such as tunnel length and curvature, the movement trajectory of the driver's line of sight in the tunnel is estimated, and optical factors such as the incident angle and distance between the line of sight and light sources at different positions are analyzed to ensure that the light intensity distribution curve along the entire tunnel is maintained within the ideal range to avoid sudden changes. At the same time, the light intensity can be smoothly transitioned by using adjustment methods such as lighting points and lamp parameters. For the curvature section, the light intensity is appropriately increased to compensate for the visual dark area.

[0095] Optionally, the mining lamp is adjusted for comfort optimization according to the lighting design parameters, so that the mining lamp provides lighting for the tunnel according to the lighting design parameters, including:

[0096] Determine the location and layout of the mining lamps according to the geometric parameters of the tunnel so that the lighting range of the mining lamps covers the tunnel;

[0097] Adjust the light intensity of the mining lamp according to the location layout and light intensity distribution curve.

[0098] It should be understood that the location layout refers to the arrangement of the miner's lamps in the tunnel, including the installation position and spacing of the miner's lamps. Designing the location layout of the miner's lamps based on the geometric parameters of the tunnel involves calculating the optimal installation position and spacing of the miner's lamps to ensure uniform lighting coverage throughout the tunnel. Computer-aided design software or professional lighting simulation software can be used to simulate the lighting range and intensity of the miner's lamps to ensure that there are no blind spots in the tunnel.

[0099] Optionally, the light intensity of the mining lamp can be adjusted according to the light intensity distribution curve to achieve uniformity and comfort of lighting. During the design process, glare control is also considered, such as using an anti-glare cover or adjusting the angle of the mining lamp to reduce direct or reflected glare, and dynamically adjusting the brightness of the mining lamp according to the light conditions and traffic flow inside and outside the tunnel.

[0100] Optionally, feedback from drivers and passengers is collected to assess lighting comfort and adjustments are made based on the feedback to enhance the visual experience for drivers and passengers while ensuring the lighting system operates efficiently and meets safety standards.

[0101] Optionally, according to the visual response characteristics, the lighting design parameters of the tunnel are determined, including:

[0102] Analyze the photosensitivity and visual comfort of human eyes at different light wavelengths based on visual response characteristics;

[0103] The light color design of the tunnel is determined based on the photosensitivity and visual comfort.

[0104] It should be understood that the color of light is determined by its wavelength, and the wavelength range of light that the human eye can perceive is approximately between 380 nanometers and 750 nanometers. Photosensitive characteristics refer to the sensitivity of the human eye to light of different wavelengths, which is related to the wavelength of light and the physiological structure of the human eye. According to the visual response characteristics and photosensitive characteristics of the human eye, the appropriate light source color is selected to improve visual comfort and work efficiency.

[0105] Optionally, according to the photosensitivity and visual comfort, a light color suitable for tunnel lighting is selected, and warm colors (such as yellow or orange light) are more comfortable under low brightness conditions.

[0106] Further references Figure 3 , as a response to the above Figure 2 In order to realize the method shown in the figure, the present application provides an embodiment of a tunnel lighting system 300, and the device embodiment is similar to Figure 2 Corresponding to the method embodiment shown, the device can be specifically applied to various electronic devices.
