Abstract: A displacement sensing system is disclosed. Two image capturing devices are settled at to opposite ends of a coordinate axis of the planar area, respectively, for capturing images of the planar area and an object placed thereon. Four pre-established LUT databases and an interactive four-matrix lookup table process are implemented to determine actual coordinates of the object on in the planar area.

Abstract: An image password lock system by tracing the position information of the organism or article feature is provided. In this embodiment, a photographic device photographs a movable target object to read a dynamic image data. Moreover, the dynamic image data has a predetermined shooting range set to be a whole-region image, and the whole-region image has a central region and a plurality of specific password regions. A target object image is displayed by a display device, and then processed by an image processing device, thereby calculating a center coordinate point of the target object image in the dynamic image data, compiling a password constituted by a movement position of the target object image, displaying the password, and validating the password. Therefore, benefits of a novel password input mode without any contact, an efficient anti-theft function and the like are provided.

Abstract: The present invention is a measurement method of three-dimensional profiles and a reconstruction system thereof using subpixel localization with color gratings and picture-in-picture switching on a single display, wherein the measurement method includes: 1. Preparation step; 2. Projection step; 3. Image extraction step; 4. Image fine-tuning step; 5. Image processing step; and 6. Reconstruction step. The system includes: a projection apparatus, emitting a grating towards a workpiece under measurement, and forming a grating image on the workpiece under measurement, the contrast values of the plurality of grating stripes of the grating image being identical; a central processing unit, using the grating image and picture-in-picture of a display thereof to fine tune and reconstruct three-dimensional profiles of the workpiece under measurement. Thereby, the grating stripes have equal contrast for easier identification; the display has switchable picture-in-picture; and an adjustment module can adjust the grating.

Abstract: This invention relates to an eye-tracking driving system, especially to an eye-tracking system controlled by the user's eye. It not only utilizes the unique eye-controlled method, but also avoids contacting with the user's eyes or skin. It is suitable for the disabled persons or the elderly so that they can drive a powered vehicle easily. The system mainly includes a display device, an eye-tracking device, a calculating device, a controller and a powered vehicle. This system can effectively capture the image around the user's eye and then precisely determine the pupil center. Based on the position of the pupil center, the power vehicle can be controlled.
