Abstract: NXP MCU level face recognition solution can add face recognition function to IoT products more quickly. The solution provides hardware reference design and software integration services with outstanding advantages, which is convenient for rapid evaluation and verification development, and meets the application needs of face recognition in various industries.
The NXP MCU-level face recognition solution is implemented using the i.MX RT106F, enabling developers to easily and conveniently add face recognition functionality to their MCU-based IoT products. This ultra-small, integrated software algorithm and hardware solution , which facilitates rapid evaluation and proof-of-concept development for developers. The SLN-VIZN-IOT development kit can create your own facial models offline without the need for cloud connectivity, reducing overall cost and design complexity.
This solution minimizes time to market, reduces risk, and reduces development effort, making it easier for many OEMs to add facial recognition capabilities, providing advanced user interfaces for smart homes, smart appliances, smart toys, and smart industries and access control features without the need for Wi-Fi and cloud connectivity, addressing many consumer privacy concerns
The i.MX RT106F is a member of the i.MX RT1060 series and will be mass-produced in April 2020, mainly for low-cost face recognition applications. In addition to the face recognition function, the i.MX RT106F has a large number of available peripherals, which can be used as the main chip for a variety of applications. The i.MX RT106F is licensed to run the NXP OASIS runtime for face recognition, which includes:
camera driver;
Image capture and preprocessing;
Face Detection;
face tracking;
face comparison
face recognition;
anti-spoofing;
face configuration;
Confidence;
face recognition authentication result;
emotion recognition;
Built-in security bootloader, application verification;
Connectivity: MQTT, lwIP, TLS; search and registration; all drivers (including wifi and bluetooth);
RTOS OTW client: OTW signature script, OTW rollback, image redundancy;
USD MSD update;
automatic verification script;
Supports MCUXpresso SDK, IDE and configuration tools.
1. The key value of the i.MX RT106F solution is reflected:
i.MX RT106F is i.MXRT1060 MCU (Arm Cortex-M7 core, 1MB SRAM): contains face recognition algorithm engine, local recognition eliminates cloud cost, latency and privacy issues;
lThe higher-end MPU solution of the MCU BOM can reduce the cost by nearly 50%: reduce the production cost of SDRAM, eMMC, PMIC, and 6-layer board;
Simpler and easier MCU platform, which is convenient for R&D personnel to develop: R&D personnel of Linux and high-end MPU are not required, and they are only required to be familiar with the real-time operating system RTOS;
NXP turnkey solution to reduce time to market: a full set of reference designs, software, schematics, layout and BOM, from design to market in less than 6 months.
