RK3568+GMSL+ADAS Multi-Channel In-Vehicle Camera Low-Cost Solution

#人工智能

The RK3568, as the most widely used domestically produced low-cost, high-performance SOC currently available on the market, boasts powerful hardware configurations. In the rapidly developing smart automotive industry, with increasing demands for image data processing, efficiently collecting data or running AI applications has become a critical need.

Our newly launched 4/8-channel GMSL acquisition/edge computing box product addresses these requirements.

Rich Interface Options

All-aluminum alloy, robust heat dissipation, fanless design

Driven by innovation in a new generation of information technology and supported by national policies, the ultra-high-definition video industry is increasingly active, forming a large-scale emerging industrial cluster. Continuously creating new application scenarios, we have developed industrial control motherboards and complete industrial PC solutions based on the Rockchip RK3568 processor to meet the demands of 8K ultra-high-definition video display.

Robotics & Industrial Cameras

For robotic vision and industrial inspection vision, Xinmai independently researches and produces various camera modules such as GMSL, FPDLink, VByone, and MIPI, offering multiple field-of-view angles and lenses for different application scenarios. We have an experienced team of image algorithm and ISP (Image Signal Processor) experts, capable of providing customers with the highest quality imaging products and services through software driver layer development, ISP algorithm and FPGA algorithm integration capabilities, and ISP image tuning for various scenarios across different SOC platforms.

GMSL is a high-speed serial interface introduced by Maxim, suitable for the transmission of video, audio, and control signals over distances of up to 15m or more using 50Ω coaxial cables or 100Ω shielded twisted pair (STP) cables. Maxim's solutions are categorized into GMSL, GMSL2, and GMSL3. GMSL2 is compatible with GMSL (first generation), allowing transceivers to be freely mixed and matched in Maxim's Camera SerDes solutions. The new GMSL3 standard (12 Gbit/s) is ADI's third-generation Gigabit Multimedia Serial Link. With this interface, image sensors can operate under the full MIPI CSI-2/D-PHY v1.2 specification (4 lanes, 2.5 Gbps each), enabling vision systems to transmit uncompressed, smooth video streams at up to 15MP@36fps or 4K@60 fps, all through a single coaxial cable (PoC). This facilitates smooth and clear sensor fusion, real-time imaging, or stereo 3D imaging. Taking ADAS cameras as an example, this is a primary application area for GMSL. Generally, in addition to sending captured image data, cameras also transmit frame sync signals, line sync signals, pixel clocks, and other information, as well as power supply. This is typically a parallel bus composed of many signal lines. Parallel buses are not advantageous for high-speed data transmission, so we need to merge these parallel signals into serial signals and transmit them at higher frequencies.

The camera module is developed and designed using an ONSEMI CMOS image sensor (AR0233), an image processor (GW5200), and a Maxim GMSL2 serializer (Max9295A). It meets automotive-grade performance requirements and delivers high-quality image effects through professional image tuning; it is also equipped with an M12 automotive-grade lens, and the module as a whole achieves an IP67 protection rating.

Smart Automotive Cameras We have designed and developed a series of compact, automotive-grade camera products specifically for the smart automotive industry, including DMS (Driver Monitoring System) cameras, OMS (Occupant Monitoring System) cameras, CMS (Camera Monitoring System) cameras, BEV (Bird's Eye View) cameras, and L2 ADAS cameras. This series of camera products can be applied in scenarios such as pre-installation (OEM), assisted driving, and autonomous driving solutions for passenger vehicles, commercial vehicles, and rail transit. These camera products are compact, convenient, and easy to install, meeting various recognition distance and field-of-view application requirements, and ensuring driving safety in harsh environments such as low light, strong light, hazy weather, rain, and snow.

ADAS (Advanced Driver Assistance System) is also known as an automatic driving assistance system. As a crucial component of intelligent driving, the widespread adoption of ADAS is a prerequisite for achieving future autonomous driving. Currently, ADAS is in a period of rapid development at the L2 level. Cameras are core sensors in the ADAS perception layer; perception-based ADAS cameras are used for active safety and require accurate image capture. The front-view integrated module is independently researched and designed by Xinmai Smart, utilizing a high dynamic range automotive-grade image sensor. It offers high reliability and can provide high-quality images for visual applications in advanced autonomous driving assistance systems. This camera module has wide applicability and can be adapted to different SOC platforms.
