Publication number: 20240081705Abstract: The present disclosure provides a non-contact fatigue detection system and method based on rPPG. The system and method adopt multi-thread synchronous communication for real-time acquisition and processing of rPPG signal, enabling fatigue status detection. In this setup, the first thread handles real-time rPPG data capture, storage and concatenation, while the second thread conducts real-time analysis and fatigue detection of rPPG data. Through a combination of skin detection and LUV color space conversion, rPPG raw signal extraction is achieved, effectively eliminating interference from internal and external environmental facial noise; Subsequently, an adaptive 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.Type: ApplicationFiled: November 16, 2023Publication date: March 14, 2024Applicant: CENTRAL CHINA NORMAL UNIVERSITYInventors: Liang ZHAO, Sannyuya LIU, Zongkai YANG, Xiaoliang ZHU, Jianwen SUN, Qing LI, Zhicheng DAI

Patent number: 11906718Abstract: The invention provides a wide-aperture spherical primary mirror off-axis afocal optical system, including a primary mirror, a secondary mirror and an aberration compensation mirror group. The primary mirror is a spherical reflector, the secondary mirror are higher-order aspherical reflectors. The primary mirror and the secondary mirror form an off-axis two-mirror system to compress the beam aperture. The aberration compensation mirror group is a coaxial reflective system that is used off-axis. The aberration compensation mirror group has focal power to produce compensation aberrations. The incident beam passes through and is reflected by the primary mirror and secondary mirror sequentially and enters the aberration compensation mirror group thereafter.Type: GrantFiled: March 18, 2022Date of Patent: February 20, 2024Assignee: SOOCHOW UNIVERSITYInventors: Xinhua Chen, Yueping Lu, Zhicheng Zhao, Qiao Pan, Weimin Shen

Patent number: 11860379Abstract: A fast assembly method of an Offner spectral imaging optical system. The Offner spectral imaging optical system is a concentric or nearly concentric optical system, that is, its primary mirror (7), convex grating (5) and three-mirror (8) are all spherical, and respective centers of curvature coincide or basically coincide. Based on the self-collimation principle, the invention quickly determines the position of the center of curvature of the spherical mirror by observing the self-collimation image after the point light source is reflected by the spherical mirror. The assembly and adjustment method provided by the invention has the characteristics of fast assembly and adjustment speed, high precision, low requirements for assembly and adjustment environment and low required equipment cost, and can quickly and effectively complete the assembly and adjustment of the Offner spectral imaging optical system.Type: GrantFiled: May 6, 2020Date of Patent: January 2, 2024Assignee: SOOCHOW UNIVERSITYInventors: Xinhua Chen, Zhicheng Zhao, Tuotuo Yang, Jiacheng Zhu, Weimin Shen

Patent number: 9064186Abstract: An example apparatus is caused to receive a video sequence of a plurality of frames, and perform a number of operations as each of at least some of the frames is received but before all of the frames are received. The apparatus is caused to calculate a score for the frame, and compare the score for the frame to a predefined threshold. The apparatus is caused to cause output of the frame as a key frame in an instance in which the frame is received within a specified period of time and the score for the frame is above the predefined threshold. Otherwise, in an instance in which none of the scores for frames received within the specified period of time is above the predefined threshold, the apparatus is caused to cause output of one of the frames received within the specified period of time as a key frame.Type: GrantFiled: December 9, 2010Date of Patent: June 23, 2015Assignee: Nokia Technologies OyInventors: Xiaohui Xie, Xiao Zeng, Yingfei Liu, Yanming Zou, Kongqiao Wang, Zhicheng Zhao, Anni Cai
