Publication number: 20240176093Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.Type: ApplicationFiled: February 5, 2024Publication date: May 30, 2024Inventors: Chao-Chang HU, Chih-Wei WENG, Chia-Che WU, Chien-Yu KAO, Hsiao-Hsin HU, He-Ling CHANG, Chao-Hsi WANG, Chen-Hsien FAN, Che-Wei CHANG, Mao-Gen JIAN, Sung-Mao TSAI, Wei-Jhe SHEN, Yung-Ping YANG, Sin-Hong LIN, Tzu-Yu CHANG, Sin-Jhong SONG, Shang-Yu HSU, Meng-Ting LIN, Shih-Wei HUNG, Yu-Huai LIAO, Mao-Kuo HSU, Hsueh-Ju LU, Ching-Chieh HUANG, Chih-Wen CHIANG, Yu-Chiao LO, Ying-Jen WANG, Shu-Shan CHEN, Che-Hsiang CHIU

Patent number: 8688274Abstract: A robot positioning method includes the following steps. A optical sensing device is configured at a front end of a robot. Then, the optical sensing device captures a calibration plate image, and a relative position of the optical sensing device with respective to a calibration plate is calculated according to a Bundle Adjustment. A robot calibration method includes the following steps. An optical sensing device is driven to rotate around a reference axis of a calibration plate, so as to calculate a translation matrix between the calibration plate and the robot, and the optical sensing device is driven to translate along three orthogonal reference axes of the calibration plate, so as to calculate a rotation matrix between the calibration plate and the robot.Type: GrantFiled: January 25, 2011Date of Patent: April 1, 2014Assignee: Industrial Technology Research InstituteInventors: Po-Huang Shieh, Shang-Chieh Lu, Bor-Tung Jiang, Kuo-Tang Huang, Chin-Kuei Chang

Patent number: 8553971Abstract: A method and system for measuring three-dimensional coordinates of an object are provided. The method includes: capturing images from a calibration point of known three-dimensional coordinates by two image-capturing devices disposed in a non-parallel manner, so as for a processing module connected to the image-capturing devices to calculate a beam confluence collinear function of the image-capturing devices; calibrating the image-capturing devices to calculate intrinsic parameters and extrinsic parameters of the image-capturing devices and calculate the beam confluence collinear function corresponding to the image-capturing devices; and capturing images from a target object by the image-capturing devices so as for the processing module to calculate three-dimensional coordinates of the object according to the beam confluence collinear function. In so doing, the method and system enable the three-dimensional coordinates and bearings of a target object to be calculated quickly, precisely, and conveniently.Type: GrantFiled: June 23, 2010Date of Patent: October 8, 2013Assignee: Industrial Technology Research InstituteInventors: Kuo-Tang Huang, Bor-Tung Jiang, Shang-Chieh Lu, Po-Huang Shieh
