I. The individual soldier image transmission system is a device used to enhance the combat capability of a single soldier or meet the specific needs of relevant personnel. It mainly provides communication support for tracking, investigation, evidence collection, and other work, and can transmit real-time video, audio, data, and positioning information from the scene back to the command center. Due to its lightweight, real-time, and anti-interference characteristics, it has become a core equipment in modern military, emergency, and security fields, and is widely used in:

Military field:

In combat, single soldier image transmission can help soldiers transmit real-time battlefield images, enemy troop deployment, terrain and other information back to the command center in a timely manner, providing a basis for command decisions and also facilitating coordinated combat among soldiers. In military training, it can be used for training evaluation and guidance, allowing instructors to real-time understand the training situation of soldiers and provide timely guidance and correction.

Emergency rescue field:

In natural disaster relief such as earthquakes, fires, floods, as well as emergency events such as urban counter-terrorism and hostage rescue, rescue personnel wear individual image transmission devices, which can transmit the real-time situation of the disaster area or site to the rear command center, facilitating the command center to reasonably allocate rescue forces, formulate rescue plans, improve rescue efficiency, and ensure the safety of rescue personnel and affected people.

Law enforcement field:

When law enforcement personnel such as public security and armed police are carrying out tasks, they can use individual image transmission devices to record the law enforcement process in real time, transmit the on-site situation to the command center or law enforcement supervision department, which not only helps the command center to command and dispatch law enforcement actions in real time, but also serves as law enforcement evidence, regulates law enforcement behavior, and ensures the fairness and transparency of law enforcement.

II. Specification Parameters

In this field, Shiyao Electronics has rich experience in project mass production and implementation, and the specifications and parameters can be referred to as follows:

III. Key Technologies:

1 Digital Image Encoding Technology:

H. 265/H.264 encoding: capable of efficiently compressing and encoding captured video images, reducing data volume while ensuring image quality, facilitating wireless transmission, and saving network bandwidth.

2 AI driven image processing algorithms

Deep learning denoising (such as 3D NR): Suppressing noise in low light environments and preserving details through AI models.

Wide Dynamic Range (WDR): solves the problem of overexposure or underexposure in high contrast scenes at night, such as car lights and dark backgrounds.

Color restoration algorithm: Using intelligent complementary color technology to restore colors close to daytime in extremely dark environments.

3 high-performance image sensors

Large size sensors (such as 1/1.8 inch or larger): a larger single pixel area captures more photons and improves signal-to-noise ratio.

Back illuminated (BSI) or stacked sensors: optimize photosensitive efficiency and reduce circuit layer obstruction of light.

High sensitivity (such as starlight/black light level sensors): supports operation in extremely dark environments below 0.0001 lux.

4 Image stabilization techniques

Optical Image Stabilization (OIS): compensates for jitter by moving the lens group or sensor, with strong real-time performance and lossless image quality, suitable for high-frequency and small jitter

Electronic Image Stabilization (EIS): Using gyroscope data to calculate the direction of shaking, cropping and dynamically adjusting the boundaries of the image through algorithms, low cost, no additional hardware required, suitable for mid to low frequency shaking, with cropping loss (redundant pixels need to be reserved), and may introduce jelly effect.

Hybrid OIS+EIS: Combining the advantages of OIS and EIS, high-frequency jitter is first processed through OIS, and then residual jitter is processed through EIS

5 large aperture lens technology

Ultra large aperture (such as F1.0 or lower): By increasing the amount of light entering the lens, the imaging brightness in low light environments is significantly improved.

Multi lens coating: reduces light reflection loss and improves transmittance

6 Multispectral Fusion Technologies

Visible light+near-infrared (NIR) fusion: Traditional infrared cameras switch to black and white mode at night, while full-color black light cameras use both visible light and near-infrared light (wavelength 700-1000nm) to synthesize color images through algorithms.

Dual spectrum or tri spectrum sensors: Some high-end models use multiple sensors to capture light in different bands and then fuse them for output.

7 Active fill light technology (optional)

No red exposure fill light: Use special wavelengths of invisible light (such as 850nm/940nm infrared) or low-intensity white light fill light to avoid detection by the human eye.

Intelligent dimming: dynamically adjust the fill light intensity according to the ambient light to avoid overexposure.

8 Network communication technology:

Utilizing mobile communication networks such as 4G and 5G, as well as technologies such as WiFi and satellite communication, to achieve long-distance data transmission between individual soldier image transmission equipment and command centers, ensuring real-time and reliable information.

IV. Product Requirements:

High definition picture quality:Equipped with top-notch image acquisition and processing chips, it can accurately capture subtle image details, achieve ultra high definition picture quality transmission, and enable the rear command center to have a clear and comprehensive understanding of the on-site situation..

Strong anti-interference ability: Adopting industry-leading anti-interference technology and built-in precision multiple signal filtering and enhancement modules, it can effectively resist various types of electromagnetic interference, ensuring stable and smooth signal transmission in complex environments.

Quick response:Equipped with a high-speed start system, soldiers can quickly complete initialization settings and establish connections upon arrival at the scene, transmitting the scene screen back to the command center in the first time, and buying precious time for commanders to timely grasp the dynamic changes of the situation and make decisions..

Good portability:The device has a small size and light weight, and its design fully considers the convenience of soldiers' wearing and operation. For example, lightweight materials are used to make helmets and backrests, which will not bring too much burden to soldiers and will not affect their combat operations..

Waterproof, dustproof and anti drop:Adopting industrial grade design and materials, it has certain waterproof, dustproof and anti drop performance, such as reaching IP67, IP68 and other waterproof and dustproof levels, and can withstand a certain height of free fall, ensuring normal operation in harsh working environments.
