摘要： An apparatus for detecting a pointer within a region of interest includes at least one pair of imaging devices. The imaging devices have overlapping fields of view encompassing the region of interest. At least one light source provides illumination across the region of interest and is within the field of view of at least one of the imaging device. A filter is associated with the at least one imaging device whose field of view sees the light source. The filter blocks light projected by the light source to inhibit the imaging device from being blinded by the projected light.

摘要： An interactive input system comprises a display panel; a first illumination source providing illumination across an outer surface of the display panel such that when a pointer is brought into proximity with the outer surface, the pointer reflects illumination from the first illumination source through the display panel; at least one imaging device having a field of view aimed at an opposite outer surface of the display panel, the at least one imaging device capturing images including illumination reflected by the pointer through the display panel; and processing structure in communication with the at least one imaging device, said processing structure processing the captured images to determine a location of the pointer relative to the outer surface.

摘要： A method of tracking an object of interest preferably includes (i) acquiring a first image and a second image representing different viewpoints of the object of interest; (ii) processing the first image into a first image data set and the second image into a second image data set; (iii) processing the first image data set and the second image data set to generate a background data set associated with a background; (iv) generating a first difference map by determining differences between the first image data set and the background data set and a second difference map by determining differences between the second image data set and the background data set; (v) detecting a first relative position of the object of interest in the first difference map and a second relative position of the object of interest in the second difference map; and (vi) producing an absolute position of the object of interest from the first and second relative positions of the object of interest.

摘要： A passive touch system includes a passive touch surface and at least two cameras associated with the touch surface. The at least two cameras acquire images of the touch surface from different locations and have overlapping fields of view. A processor receives and processes images acquired by the at least two cameras to detect the existence of a pointer therein and to determine the location of the pointer relative to the touch surface. Actual pointer contact with the touch surface and pointer hover above the touch surface can be determined.

摘要： A fastening system for a vehicle is provided. The fastening system includes a metal clip which is easily inserted and removed from a polymeric doghouse. The doghouse is integrally molded with a vehicle interior trim component. After the clip is inserted into the doghouse, the trim component may be snapped into place over a structural pillar by inserting the clip into an aperture and the pillar. The fastening system is designed such that it will not fail, and the trim component will remain in place, when an air bag adjacent to the trim component is deployed. If desired, the trim component can be easily removed from the support pillar by sliding the trim component, and the attached doghouse, away from the clip. The clip can then be removed from the pillar, a new one inserted into the doghouse, and the trim component can be reused.

摘要： A touch system includes a touch surface and at least two cameras associated with the touch surface. The at least two cameras acquire images of the touch surface from different locations and having overlapping fields of view. A digital signal processor is associated with each camera. The digital signal processors process pixel data acquired by selected pixel subsets of the at least two digital cameras to generate pointer characteristic data when a pointer exists in the acquired images. The pointer characteristic data identifies edges of the pointer. A master digital signal processor triangulates the edge information in the pointer characteristic data to determine a bounding area that represents a pointer perimeter.

摘要： A camera-based touch system (50) includes a passive touch surface (60) and at least two cameras (63) associated with the touch surface. The at least two cameras (63) have overlapping fields of view (FOV) encompassing the touch surface. The at least two cameras (63) acquire images of the touch surface from different locations and generate image data. A processor (54) receives and processes image data generated by the at least two cameras to determine the location of the pointer relative to the touch surface when the pointer is captured in images acquired by the at least two cameras. Actual pointer contact with the touch surface and pointer hover above the touch surface can be determined.
