The UHD fusion camera system outlined in this design is engineered to facilitate the real-time acquisition of both visible and infrared light image information. The system not only performs real-time fusion of these images but also encodes them using the H.265 standard for efficient transmission. The camera is designed to transmit the processed data via the RTP (Real-time Transport Protocol), ensuring timely delivery of video streams. Below are the specific functional requirements of the system:

(1) Camera Mode Configuration

The camera system is equipped with configurable parameters that allow for adaptability to diverse acquisition scenarios. Key parameters include:

Image Sensor Resolution: The resolution of the image sensors can be adjusted to meet specific application needs.
Exposure Time: This parameter can be modified to optimize image quality under varying lighting conditions.
Frame Rate: The camera supports different frame rates, which can be configured through low-speed serial interfaces such as SPI (Serial Peripheral Interface), IIC (Inter-Integrated Circuit), and UART (Universal Asynchronous Receiver-Transmitter).

These configurations enable the camera to dynamically respond to changes in the environment, ensuring optimal performance.

(2) Image Acquisition Function

The system is capable of receiving and processing pixel data from both visible and infrared light sensors in real time. This dual capability allows for a comprehensive capture of the scene, enhancing the overall quality of the output images.

(3) Image Fusion Function

One of the core functionalities of the UHD fusion camera is its ability to perform real-time fusion of the acquired visible and infrared light images. This is achieved through sophisticated image fusion algorithms that integrate the data from both sensors, resulting in a single, high-fidelity image that retains the strengths of both imaging modalities.

(4) Video Stream Encoding and Transmission Function

To facilitate efficient data handling and transmission, the system incorporates advanced video encoding capabilities. It supports both H.264 and H.265 encoding standards, with H.265 offering improved compression efficiency and quality. This allows for the transmission of high-definition video streams over networks, making it suitable for applications that require real-time video feeds.

In summary, the UHD fusion camera system represents a significant advancement in imaging technology, combining the strengths of visible and infrared imaging through sophisticated hardware design and functional capabilities. By addressing the limitations of single-sensor systems, this camera design opens up new possibilities for enhanced imaging in various applications, from surveillance to industrial monitoring.
