Description

Technical Field

[0001] This application relates to the field of military camouflage technology, and in particular to a military camouflage system, method, medium and terminal based on adaptive spectral matching. Background Technology

[0002] Traditional military camouflage primarily uses static camouflage, such as camouflage netting and coatings. The optical characteristics (such as color and pattern) and spectral characteristics (especially in the near-infrared to mid- and far-infrared bands) of this static military camouflage method are typically fixed and cannot adapt to changes in the surrounding environment. Therefore, it is difficult to dynamically adjust to changes in the surrounding environment in various complex scenarios, such as changes in light intensity from jungle to desert, from day to night, from sunny to rainy weather, the alternation of day and night, and seasonal changes.

[0003] With the rapid development of modern optoelectronic reconnaissance equipment, such as visible light cameras, low-light night vision devices, infrared thermal imagers, and spectrometers, these modern optoelectronic reconnaissance systems have evolved into multi-spectral, high-precision integrated detection systems. They integrate technologies such as high-resolution visible light imaging, low-light night vision, infrared thermal imaging, and spectral analysis, which can easily detect the spectral anomalies and spatiotemporal inconsistencies of static camouflage, making traditional military static camouflage extremely easy to detect.

[0004] Although there are some dynamic camouflage concepts based on materials such as electronic paper or liquid crystal, they still generally suffer from low refresh rates, limited spectral coverage (usually limited to visible light), lag in environmental perception response, and the inability to achieve active matching in a wide spectral range (especially in the mid- and far-infrared bands). These technical problems make it difficult to meet the urgent needs of modern complex battlefields for highly adaptable, full-spectrum stealth.

[0005] Therefore, it is necessary to provide a military camouflage system, method, medium, and terminal based on adaptive spectral matching to solve the aforementioned problems in the prior art. Summary of the Invention

[0029] Before providing a further detailed description of the present invention, the nouns and terms used in the embodiments of the present invention are explained, and the nouns and terms used in the embodiments of the present invention are subject to the following interpretations:

[0030] <1> Multi-chip LED (mc-LED): Two or more LED chips with different functions, different wavelengths or the same wavelength are integrated on the same package or substrate through precision semiconductor technology to form a single, compact optoelectronic device.

[0031] <2> Pulse Width Modulation (PWM) is a technique for digitally encoding analog signal levels. It effectively controls the average power delivered to the load by changing the pulse width (i.e., duty cycle) of a series of square waves.

[0032] To facilitate understanding of the embodiments of this application, firstly, in conjunction with Figure 1 Detailed explanation. Figure 1 A block diagram of an adaptive spectral matching-based military camouflage system according to an embodiment of the present invention is shown. The adaptive spectral matching-based military camouflage system 100 in this embodiment includes:

[0033] A data acquisition module 101 is used to acquire multispectral environmental data of the surrounding environment of the camouflage carrier; a processing and control module 102 is communicatively connected to the data acquisition module 101, used to process the received multispectral environmental data, and generate a spectrally matched control command set; a pixel driving module 103 is communicatively connected to the processing and control module 102, used to output driving signal information according to the received spectrally matched control command set; a display array module 104 is communicatively connected to the pixel driving module 103, used to emit light of different intensities according to the input driving signal information, and mix these lights to output a spectrum that matches the surrounding environment of the camouflage carrier, so as to camouflage the camouflage carrier in its surrounding environment.

[0034] The data acquisition module senses the dynamic changes of the surrounding environment of the camouflage carrier in real time and collects multispectral environmental data of the current surrounding environment of the camouflage carrier. The processing and control module processes the received multispectral environmental data to obtain a spectral matching control command set. The pixel driving module outputs driving signal information according to the received spectral matching control command set. The display array module emits light of different intensities according to the driving signal information and mixes these lights to output a composite spectrum. The spectral characteristics of the composite spectrum match the current surrounding environment of the camouflage carrier, thereby enabling the camouflage carrier to blend into the current environment. This improves the speed at which the surface of the camouflage carrier adapts to the new surrounding environment and covers a wide spectral range, realizing active matching of the spectrum of the camouflage carrier and the surrounding environment within a wide spectral range.

[0035] In some embodiments of this application, such as Figure 2 As shown, the display array module includes: a display panel disposed on the outer surface of the camouflage carrier; multiple pixel units, an array of which are distributed on the display panel; each pixel unit includes multiple LED chip sub-units, which have different emission wavelengths and are connected to the same anode and cathode via bonding wires. By mixing the light outputs of each pixel unit, a spectrum that highly matches the spectral reflectance curve of the surrounding environment of the camouflage carrier is precisely synthesized, allowing the camouflage carrier to perfectly blend into the natural environment and achieve an adaptive camouflage effect.

[0036] Leveraging the inherent advantages of LED technology, such as high brightness, high refresh rate, programmable spectrum, and wide coverage (extending from visible light to infrared), the display array module can analyze the spectral and texture features of the surrounding environment in real time and drive flexible or rigid display array modules to match, thereby achieving adaptive spectral matching for adaptive stealth in the visual, near-infrared (NIR), and even short-wave infrared (SWIR) bands. This enables the display array module to achieve intelligent adaptive camouflage technology that can perceive the environment in real time and actively and dynamically match its multispectral characteristics.

[0037] Specifically, the display panel selects either a rigid or flexible LED panel depending on the carrier to be disguised. Preferably, the display panel uses a high-density, flexible, and customizable LED panel to ensure complete coverage of the disguise carrier and achieve a better camouflage effect. Each pixel unit is not a simple RGB (red, green, blue) tri-color LED, but a multi-chip LED, meaning each pixel unit is composed of multiple LED chip sub-units. Multiple LED chip sub-units with different peak wavelengths are on the same packaging carrier, and each LED chip sub-unit has its own function and core technical parameters (peak wavelength). This physical layout is the physical basis for achieving broad spectrum coverage (from visible light to short-wave infrared light). For example, each pixel unit consists of a first LED chip sub-unit, a second LED chip sub-unit, a third LED chip sub-unit, a fourth LED chip sub-unit, a fifth LED chip sub-unit, and a sixth LED chip sub-unit. The LED chip subunit comprises the following components: a first blue chip with a peak wavelength of 450 nm; a second green chip with a peak wavelength of 530 nm; a third red chip with a peak wavelength of 630 nm; a fourth near-infrared chip with a peak wavelength of 850 nm; a fifth near-infrared chip with a different wavelength of 940 nm; and a sixth short-wave infrared chip with a peak wavelength of 1550 nm. This covers a broad spectral range from visible light to short-wave infrared light, achieving adaptive spectral matching across the wide spectrum. Furthermore, the first, second, third, fourth, fifth, and sixth LED chip subunits are connected to common anode and cathode pins via bonding wires, a common package electrical structure that simplifies external circuit design.

[0038] In some embodiments of this application, such as Figure 2 As shown, the pixel driving module includes: a chip driving subunit corresponding to the LED chip subunit; each chip driving subunit is used to independently control the luminous intensity and duty cycle of the corresponding LED chip subunit so that each LED chip subunit emits light of a specific intensity.

[0039] In terms of physical layout, although each LED chip subunit shares the same anode and cathode, each LED chip subunit can be independently controlled by the corresponding chip driver subunit. The pixel driver module connected to the LED chip subunit provides an independent driving channel (such as Channel0-Channel5) for each LED chip subunit. By precisely controlling the current injected into each LED chip subunit, the luminous intensity and duty cycle of each LED chip subunit can be independently adjusted. Finally, the desired spectrum is mixed macroscopically. The spectral reflectance curve output after mixing is highly matched with the spectral reflectance curve of the surrounding environment, realizing precise dynamic matching between the camouflage carrier and the background environment.

[0040] Specifically, the pixel driving module includes multiple high-precision, multi-channel constant current chip driving sub-units. Each chip driving sub-unit is connected to the corresponding LED chip sub-unit of the pixel unit. The chip driving sub-unit receives spectral matching control commands from the processing and control module, which are usually pulse width modulation (PWM) signals and current control signals. Each channel independently drives an LED chip sub-unit of a certain wavelength, controlling the luminous intensity and duty cycle of each LED chip sub-unit with extremely high precision and speed, thereby achieving the desired spectral and brightness output.

[0041] For example, a first chip driver subunit is connected to a first LED chip subunit (blue chip), providing an independent Channel 0 driving channel to drive the first LED chip subunit (blue chip) to emit blue light of a specific intensity; a second chip driver subunit is connected to a second LED chip subunit (green chip), providing an independent Channel 1 driving channel to drive the second LED chip subunit (green chip) to emit green light of a specific intensity; a third chip driver subunit is connected to a third LED chip subunit (red chip), providing an independent Channel 2 driving channel to drive the third LED chip subunit (red chip) to emit red light of a specific intensity; a fourth chip driver subunit is connected to a fourth LED chip subunit (nearly 850nm peak wavelength). The display array module is connected to a fourth LED chip subunit (a near-infrared chip with a peak wavelength of 850nm) via a Channel 3 driving channel, providing an independent Channel 3 driving channel to drive the fifth LED chip subunit (a near-infrared chip with a peak wavelength of 940nm) to emit near-infrared light with a peak wavelength of 940nm. A sixth chip driving subunit is connected to a sixth LED chip subunit (a short-wave infrared chip), providing an independent Channel 5 driving channel to drive the sixth LED chip subunit (a short-wave infrared chip) to emit short-wave infrared light of a specific intensity. These lights are mixed and output to create a spectrum that matches the surrounding environment of the camouflage carrier, ensuring that the optical pattern presented by the display array module is consistent with the environment surrounding the camouflage carrier, thereby enabling the camouflage carrier to blend into its surroundings.

[0042] Traditional RGB LED technology is limited by its inherent technical characteristics, offering only limited coverage in the visible light spectrum (400nm-700nm). It lacks output in the near-infrared (NIR) and short-wave infrared (SWIR) bands, creating a noticeable "black hole" under infrared reconnaissance equipment, resulting in the absence of these bands. Furthermore, its wide-band emission makes it unable to accurately simulate the complex spectral reflectance curves of natural objects, resulting in coarse control and easy exposure to the surrounding environment, making it easily identifiable by reconnaissance equipment. In contrast to traditional RGB LED technology, this application's military camouflage system based on adaptive spectral matching incorporates a display array module integrating LED chip sub-units of multiple wavelengths, covering the complete reconnaissance bands from visible light to near-infrared and short-wave infrared. By independently driving multiple corresponding narrowband LED chip sub-units and mixing their light, a complex spectrum that highly matches the measured curve of the background environment can be synthesized, allowing for precise control and achieving highly efficient stealth. Meanwhile, the military camouflage system based on adaptive spectral matching proposed in this application can not only achieve pixel-level fusion in the visible light band, but more importantly, it can also achieve perfect stealth in the infrared band through spectral matching.

[0043] In some embodiments of this application, such as Figure 3 As shown, the data acquisition module includes multiple sensor units, which are evenly arranged on the surface of the camouflage carrier to synchronously or alternately acquire multispectral environmental data of the surrounding environment. The data acquisition module is designed to sense the surrounding environment of the camouflage carrier. After the distributed sensor units are activated, they synchronously or alternately acquire multispectral raw data of the surrounding environment from all directions of the camouflage carrier, including but not limited to images and spectral information in the visible light, near-infrared, and short-wave infrared bands.

[0044] Specifically, multiple sensor units are evenly arranged on the outer surface of the camouflage carrier, enabling them to acquire multispectral environmental data from all directions without blind spots. These multiple sensor units can simultaneously acquire multispectral environmental data, providing complete environmental information around the camouflage carrier, and can also operate in a time-sharing manner, reducing system power consumption and data processing load. The multispectral environmental data includes multispectral images and spectral data. Exemplarily, the sensor units may employ multispectral imagers, hyperspectral imagers, etc., but this application does not specifically limit their use.

[0045] In some embodiments of this application, such as Figure 3As shown, the processing and control module includes: a data fusion unit, used to fuse the multispectral environmental data collected by each of the sensor units to obtain panoramic multispectral environmental image data; a feature extraction unit, used to extract key features of the surrounding environment of the camouflage carrier from the fused panoramic multispectral environmental image data; the key features include one or more of spectral features, spatial features, and brightness level features; and a matching decision unit, used to calculate a set of control instructions for spectral matching based on one or more of the extracted spectral features, spatial features, and brightness level features.

[0046] The design of the processing and control module is used for real-time fusion analysis of multispectral environmental data. The processing and control module receives multispectral environmental data collected by multiple sensor units, extracts key features from the multispectral environmental data, and generates optimal control commands to drive each LED chip subunit of the display array module, thereby achieving precise spectral and spatial camouflage.

[0047] Specifically, due to differences in physical location, viewing angle, and resolution among different sensor units, the data fusion unit first aligns the multispectral environmental data of different bands collected by different sensor units, and then integrates these aligned data to generate a coherent panoramic multispectral environmental image. For the fused panoramic multispectral environmental image, the feature extraction unit analyzes the key environmental features in real time from the fused data, including: spectral features (spectral reflectance curve), spatial features (texture, contour), and brightness level features. Based on the extracted key features, the matching decision unit calls the built-in database or intelligent algorithm to calculate the optimal camouflage scheme and generates a detailed spectral matching control instruction set. The pixel driving module converts the spectral matching control instruction set into driving signal information. This driving signal information includes the spectrum, intensity, and timing that each LED chip subunit of each pixel unit on the display array module needs to emit. This ensures that each LED chip subunit emits light according to the calculated spectrum, intensity, and timing, and these lights are mixed to output the required spectrum. That is, the mixed output spectral reflectance curve is consistent with the spectral reflectance curve of the surrounding environment, allowing the camouflage carrier to blend into the surrounding environment and achieve an adaptive intelligent camouflage effect.

[0048] In some embodiments of this application, the military camouflage system based on adaptive spectral matching further includes an auxiliary support module for providing power, heat dissipation, and communication for the data acquisition module, the processing and control module, the pixel driving module, and the display array module. Through the design of the auxiliary support module, the military camouflage system based on adaptive spectral matching of this application is supported, providing stable power supply, effective heat dissipation, reliable communication, and robust protection for the entire camouflage platform, ensuring that the military camouflage system based on adaptive spectral matching of this application operates continuously, covertly, and reliably in complex battlefield environments.

[0049] In some embodiments of this application, the auxiliary support module includes: a power supply unit for supplying power to the data acquisition module, the processing and control module, the pixel driving module, and the display array module; a thermal management unit for dissipating heat from the data acquisition module, the processing and control module, the pixel driving module, and the display array module; and a communication interface for transmitting data between the data acquisition module, the processing and control module, the pixel driving module, and the display array module.

[0050] The workflow of the military camouflage system based on adaptive spectral matching in this application is as follows: A display array module is set on the outer surface of the camouflage carrier, and a distributed sensor unit set on the surface of the camouflage carrier is activated to synchronously or alternately collect multispectral raw environmental data of the current surrounding environment from all directions of the camouflage carrier; the processing and control module fuses and analyzes the multispectral environmental data in real time, extracts key features from the multispectral environmental data, and generates optimal control instructions for each LED chip subunit of each pixel unit of the display array module to achieve precise spectral and spatial camouflage. At the same time, the spectral matching control instruction set generated by the processing and control module is sent to the pixel driving module; the pixel driving module converts the digital instructions into precise high-precision current signals and PWM signals; the display array module receives the electrical signals and drives the corresponding LED chip subunit of the pixel unit to emit light, and finally dynamically generates a camouflage pattern that is highly integrated with the surrounding environment in terms of spectrum and texture on the surface of the display panel, thereby making the camouflage carrier camouflaged in the current surrounding environment.

[0051] To achieve optimal and sustained camouflage, the adaptive spectral matching-based military camouflage system of this application can activate a display effect feedback loop. The data acquisition module will again acquire a comprehensive image of the current display panel and its surrounding environment, and send this data back to the processing and control module. The processing and control module compares the "display effect" with the "ideal environmental target." If there is a deviation, the drive commands are fine-tuned, thereby realizing the self-calibration and continuous optimization of the adaptive spectral matching-based military camouflage system of this application, forming an intelligent closed loop.

[0052] This application presents a military camouflage system based on adaptive spectral matching, which is an innovative systemic solution that organically integrates multiple cutting-edge technologies such as spectroscopy, semiconductor display, image processing, and automatic control, and applies them to the special scenario of military camouflage. The system acquires spectral and image information of the surrounding background in real time through a data acquisition module; analyzes and extracts key features (average spectrum, texture, edge, brightness distribution) through a high-speed data processing and control module; then generates the optimal camouflage display scheme through an intelligent matching algorithm; finally, the pixel driving module controls each pixel on the display panel, causing the display array module to emit light that is highly matched to the background environment in terms of spectrum and space, allowing the camouflage carrier to blend into the surrounding environment and evade enemy electro-optical reconnaissance. This system begins by sensing the surrounding environment, generating camouflage commands through processing and decision-making, and finally executing the display. It can also be optimized through feedback. The entire process is high-speed and automatically loops, ensuring that moving military targets (camouflage carriers) can continuously remain hidden in the dynamically changing background environment.

[0053] Furthermore, such as Figure 4 As shown, a tank serves as a specific example using camouflage as the carrier: a flexible display panel is attached to the outer surface of the tank, and six sensor units are installed around the hull and on the top. Specifically, with the tank as the center, serving as the carrier for all sensor units, the distributed sensors are as follows: front and rear sensors, used to sense the environment in the front and rear directions of the tank; left and right sensors, used to sense the environment on the left and right sides of the tank, typically symmetrically distributed to ensure no blind spots; and a top sensor, used to sense the environment above, such as the sky and the tops of buildings, to achieve a complete, all-around, no-blind-spot perception network around the tank. As the tank moves from the asphalt road into the jungle, the sensor units on its top and sides immediately capture the highly reflective green light of the vegetation, specific near-infrared "red edge" features, and complex leaf textures. The processing and control module quickly analyzes the main spectral characteristics of the background environment: a 550nm green peak, a 720nm NIR high reflectivity area, and a texture feature of small, irregular spots. The system described in this application retrieves the "temperate jungle" mode from the database and fine-tunes it using real-time data. After the command is issued, the drive chip subunit controls the green and NIR chips in each pixel to emit brightly, while the blue and red chips emit at low intensity, to accurately match the vegetation spectrum and generate a jungle camouflage texture pattern in space. Within seconds, the tank's appearance changes from a gray road mode to a green jungle mode, not only blending into the jungle to the naked eye but also appearing as a natural vegetation background under enemy night vision devices and infrared reconnaissance equipment, thus achieving efficient stealth.

[0054] This application's military camouflage system based on adaptive spectral matching achieves full-spectrum, dynamic adaptive stealth of military targets across the visible, near-infrared, and short-wave infrared bands by real-time sensing of the surrounding environment's spectrum and texture, driving the display array module to perform high-precision matching. This significantly improves the reliability and battlefield survivability of the camouflage system. Furthermore, through innovative system architecture and algorithm integration, it can be industrialized and is applicable not only to military equipment camouflage but also to police concealment, field scientific research observation, and high-end architectural landscape integration, demonstrating broad market prospects.

[0056] Step S51: Collect multispectral environmental data of the surrounding environment of the camouflage carrier;

[0057] Step S52: Process the received multispectral environmental data and generate a set of control instructions for spectral matching;

[0058] Step S53: Output drive signal information according to the received spectral matching control command set;

[0059] Step S54: Based on the input driving signal information, emit light of different intensities, and mix these lights to output a spectrum that matches the surrounding environment of the camouflage carrier, so as to camouflage the camouflage carrier in its surrounding environment.

[0077] In summary, addressing the technical problems of low refresh rate, limited spectral coverage, delayed environmental perception response, and inability to achieve active matching across a wide spectral range in existing technologies, this application provides a military camouflage system, method, medium, and terminal based on adaptive spectral matching. The system utilizes a data acquisition module to perceive the dynamic changes in the environment surrounding the camouflage carrier in real time and collect multispectral environmental data. A processing and control module processes the received multispectral environmental data to obtain a spectral matching control command set. A pixel driving module outputs driving signal information based on the received spectral matching control command set. A display array module emits light of different intensities based on the driving signal information and mixes these lights to output a composite spectrum. The spectral characteristics of this composite spectrum match the current environment of the camouflage carrier, thereby enabling the camouflage carrier to blend into the current environment. This improves the speed at which the camouflage carrier surface adapts to new surrounding environments and covers a wide spectral range, achieving active matching of the camouflage carrier's spectrum with the surrounding environment across a broad spectral range. Therefore, this application effectively overcomes the various shortcomings of existing technologies and has high industrial applicability.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application.
