Patent number: 11694337Abstract: A processing path generating method includes the following steps. An image-capturing device is moved to the first position of the region of interest to perform an image-capture on a workpiece, so as to obtain a first image. The image-capturing device is moved to a second position to perform the image-capture on the workpiece, so as to obtain a second image. A first edge characteristic and a second edge characteristic of the workpiece are obtained according to the first image and the second image. Three-dimensional edge information of the workpiece is fitted according to the first edge characteristic and the second edge characteristic. A processing path is generated according to the three-dimensional edge information.Type: GrantFiled: March 31, 2022Date of Patent: July 4, 2023Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Meng-Chiou Liao, Chang-Lin Wang, Chin-Ming Chen, Chien-Yi Lee, Po-Hsun Wu

Patent number: 10274342Abstract: A rotating sensing device includes a base, a rotating element, at least one magnetic element set, at least one magnetic sensing element set, and a processing unit. The magnetic element set is arranged on the rotating element and includes an axial magnetic element and a radial magnetic element. The magnetic sensing element set is arranged on the base and includes an axial magnetic sensing element and a radial magnetic sensing element. When the rotating element is rotated relatively to the base, a magnetic variation relative to the axial magnetic element and a magnetic variation relative to the radial magnetic element are respectively sensed by the axial magnetic sensing element and the radial magnetic sensing element, so as to generate a sensing signal. The processing unit is adapted to obtain a rotation speed, a loading value, and a deflection value. In addition, a rotating sensing method is also provided.Type: GrantFiled: December 29, 2016Date of Patent: April 30, 2019Assignee: Industrial Technology Research InstituteInventors: Chin-Ming Chen, Po-Hsiu Ko, Szu-Chia Lin, Meng-Chiou Liao

Patent number: 8752967Abstract: A projection system and an image processing method thereof are provided. The system includes a projector module, a photography module and a processing module. The projector module projects a first image frame to an object surface. The photography module photographs the object surface to derive a second image frame including the first image frame and an indication point, wherein the indication point is formed by light projected on the object surface by an external device. The processing module analyzes the second image frame to derive coordinate of the indication point in the second image frame, derives coordinate of at least a feature point of the first image frame in the second image frame according to a linear-approximation method, and transforms the coordinates of the indication point in the second image frame to the coordinates in the first image frame by using two-dimensional coordinate transformation equations.Type: GrantFiled: October 13, 2011Date of Patent: June 17, 2014Assignee: Aptos Technology Inc.Inventors: Yung-Ching Hung, Meng-Chiou Liao
