摘要:
A method of image-tracking by using an image capturing device. The method comprises: performing an image-capture of a scene by using an image capturing device; and tracking movement of the image capturing device by analyzing a set of images by using an image processing algorithm.
摘要:
Method and apparatus are provided for image based positioning comprising capturing a first image with an image capturing device. Wherein said first image includes at least one object. Moving the platform and capturing a second image with the image capturing device. The second image including the at least one object. Capturing in the first image an image of a surface; capturing in the second image a second image of the surface. Processing the plurality of images of the object and the surface using a combined feature based process and surface tracking process to track the location of the surface. Finally, determining the location of the platform by processing the combined feature based process and surface based process.

A planet gear speed reducer includes a casing having a receiving space defined therein for receiving an output shaft and an input shaft. The output shaft and the input shaft are longitudinally connected to each other. The output shaft includes a planet gear arm and a drive axle concentrically and longitudinally extending the planet gear arm. A third bearing is mounted in a bottom of the planet gear arm. The input shaft has a sun gear axle concentrically extends therefrom and engaged to the multiple planet gears on the planet gear arm. A fourth bearing is securely sleeved on a heel of the sun gear axle and an outer periphery of the fourth bearing is securely received within annular protrusion. A stub concentrically and longitudinally extends from a free end of the sun gear axle and securely received in the third bearing.

An alternating phase shift mask. The alternating phase shift mask includes a transparent substrate, a light-shielding layer disposed on the transparent substrate to define a transparent array consisting of a plurality of first phase rows and a plurality of second phase rows alternately interposed between the first phase rows. The alternating phase shift mask further comprises a phase interference enhancement feature disposed a predetermined distance from the outermost row of the transparent array, wherein the phases of the phase interference enhancement feature and the outermost row are reverse.

A phosphor device of an illumination system is provided. The illumination system emits a first waveband light and has an optical path. The phosphor device includes a first section and a first phosphor agent. The first phosphor agent is coated on the first section. After the first waveband light is received by the first phosphor agent, the first waveband light is converted into a third waveband light, and the third waveband light is directed to the optical path, so that the third waveband light is separated into at least two color lights along the optical path.

A method of image-tracking by using an image capturing device (12). The method comprises: performing an image-capture of a scene (54) by using an image capturing device; and tracking movement (62) of the image capturing device (12) by analyzing a set of images by using an image processing algorithm (64).
摘要:
Disclosed is a method of manufacturing an optical film, in which a transparent cycloolefin copolymer (COC) material is used as a raw material thereof and solved in a solvent to constitute a solution for forming the optical film. The thus formed optical film may have optical characteristics similar to those of prior-art optical film. Therefore, a retardation film or a protective film may be manufactured using cheaper and more accessible raw materials.
