This work is a thermometer based on face recognition. The appearance of the work is a temperature measuring gun. The work is mainly composed of the K210 kit provided by Sipeed, Hetai HT32F52352 chip, WIFI communication module, cloud server, IC card reader module and LDO power module. etc., the K210 is controlled by the HT32 chip to collect images in real time, and the collected images are processed locally. If there is facial information in the collected images, the facial features are extracted based on the face model, and then compared with the person in the image library. Compare the feature values of the face, and return the recognition results to the HT32 chip and the host computer for us to view the temperature measurement results. The following is a physical picture of the overall work and an introduction to its functions.
The LPCXpresso family of boards provides a powerful and flexible development system for NXP Cortex-M microcontrollers. The LPCXpresso4367 board was developed by NXP to enable evaluation and prototyping of the LPC4300 series MCUs, featuring the LPC4367 in a 100-pin BGA package. LPCXpresso™ is a low-cost development platform provided by NXP that supports NXP's Arm-based microcontrollers. The platform includes a simplified Eclipse-based IDE and low-cost target boards with a JTAG debugger. LPCXpresso is an end-to-end solution that supports embedded engineers through every step of application development, from initial evaluation to final production.
The full-bridge DC-DC switch mode power supply reference design is based on V-Series MCUs and is intended to provide examples of power conversion applications. A full-bridge DC-DC converter is a transformer-isolated step-down converter. The full-bridge topology consists of a full-bridge inverter module, transformer, synchronous rectifier module and filter.
