摘要： The present invention provides a multi-touch position tracking technique and an interactive system and a multi-touch interactive image processing method using the same. In the present invention, a light guide element is designed to comprise frustrating structures to frustrate total internal reflection (TIR) so that the light beam therein can be dispersed to form a dispersed optical field distribution. The dispersed optical field is used to respond a physical relation between an object and the light guide element.

摘要： A three-dimensional scanning system, that scans a three-dimensional object and calculates a three-dimensional coordinate data from a surface of the object. The three-dimensional scanning system has a photoelectron detector, a rotational scanning device, a drive device, an image processing circuit, and an operational control device. The photoelectron detector projects a light plane onto the object and then receives a reflected light stripe. The rotational scanning device couples with the photoelectron detector that rotates on a fixed pivot and allows the light stripe to scan on the object's surface. The drive device couples to and operates the photoelectron detector and the rotational scanning device. The image processing circuit can grab the light stripe instantly. The operational control device couples with the rotational scanning device and the photoelectron detector. The operational control device controls the motion of the rotational scanning device and the scanning position of the photoelectron detector, and then calculates the three-dimensional coordinates of the object.

摘要： A 3D shape-measuring apparatus using biaxial anamorphic magnification comprises a light source that projects a light onto an object surface to be sensed. Via an electrical image-grabbing device, such as CCD camera, the light reflected from the object is grabbed to determine the coordinate locations sensed on the object. Before the electrical image-grabbing device, the light reflected from the object passes respectively through a curved reflecting mirror or an assembly of telecentric cylindrical lenses to adjust an image magnification along the light projection direction, and an assembly of cylindrical lenses to adjust an image magnification along a direction perpendicular to the light projection direction. Thereby, resolution nonuniformity with respect to near and far distance is resolved while the observable range of the CCD camera can further be efficiently changed into a measurable field.
