Title: Jianwen Sun: A Pioneer in Non-Contact Fatigue Detection and Educational Big Data Analysis
Introduction
Jianwen Sun is an accomplished inventor based in Hubei, China, recognized for his significant contributions to the fields of fatigue detection systems and educational big data analysis. With a portfolio of two patents, he has made strides in leveraging technology to enhance both health monitoring and educational experiences.
Latest Patents
One of Jianwen Sun's notable patents is the "Non-contact fatigue detection system and method based on RPPG." This innovative system employs multi-thread synchronous communication for the real-time acquisition and processing of remote photoplethysmography (rPPG) signals, enabling effective fatigue status detection. The method utilizes two threads; the first manages real-time data capture, storage, and concatenation, while the second conducts the analysis and fatigue detection. By integrating skin detection and LUV color space conversion, the system effectively extracts rPPG raw signals, minimizing interference from environmental noise. An advanced multi-stage filtering process enhances the signal-to-noise ratio, and a multi-dimensional fusion CNN model ensures accurate detection of respiration and heart rate. Ultimately, this system achieves early fatigue detection with remarkable accuracy.
Additionally, Sun holds a patent for a "Method and system for analyzing educational big data on the basis of maps." This method involves acquiring educational resource data, organizing it into structured databases, and constructing thematic map layers for analysis. By classifying and indexing data according to various themes, the system superimposes these thematic layers onto base maps, enabling comprehensive data analysis and results extraction. This approach not only illustrates user learning preferences but also organizes region analysis results based on specific user inquiries.
