Patent number: 11010927Abstract: A method and a system for generating dynamic map information with environment information are provided, wherein the system includes a cloud server, multiple relay hosts distributed around the environment and multiple vehicle devices each installed respectively in different vehicles. Each vehicle device includes a LiDAR sensor and a camera for sensing the environment to respectively generate point cloud data and image data. When the point cloud data from different vehicles are transmitted to a neighboring relay host, the relay host performs a multi-vehicle data integration mode to merge the point cloud data and obtain 3D coordinates information of objects in the environment according to the merged data. Based on the 3D coordinates information of objects, the cloud server generates and transmits dynamic map information to the vehicles. By sharing sensing data of different vehicles, the sensing area of each vehicle is expanded to mitigate dark zones or blind zones.Type: GrantFiled: October 16, 2019Date of Patent: May 18, 2021Assignee: AUTOMOTIVE RESEARCH & TESTING CENTERInventors: Hsuan-Ta Lin, Cheng-Kai Wang, Chun-Yao Shih

Patent number: 8934093Abstract: The invention relates to a crystal fiber, a Raman spectrometer using the same and a inspection method thereof. The crystal fiber comprises a sapphire crystal is doped with two transition metals having different concentrations. An excitation light beam at a specific wavelength can propagate along the crystal fiber to generate a narrow-band light beam and a wide-band light beam to project on a specimen. Raman scattered light is emitted from the specimen. The wavelength of the Raman scattered light falls within the wavelength range of the wide-band light beam so that the wide-band light beam is enhanced at some characteristic wavelengths to facilitate Raman spectroscopy.Type: GrantFiled: February 21, 2012Date of Patent: January 13, 2015Assignee: National Taiwan UniversityInventors: Pi Ling Huang, Kuang-Yu Hsu, Cheng-Kai Wang, Edmund Sun, Sheng-Lung Huang
