Abstract: A distance measuring system includes a light emitting member, an optical member, an image sensing member, and a computing member. The light emitting member provides a light beam to an object. The optical member is disposed on a transmission path of the light beam reflected by the object. The image sensing member is disposed on a transmission path of the part of the light beam passing through the optical member, and the image sensing member has an image sensing area for receiving the part of the light beam passing through the optical member and receiving the part of the light beam not passing through the optical member. The computing member compares a difference between the deformation area and the non-deformation area of the object image so as to obtain a distance variation of the object.

Abstract: An image determining method for scanning an image and determining specific image pixels of a specific image. The method comprises: determining at least one pixel in a first row having brightness value larger than a threshold value as the specific image pixel; defining a leftmost pixel and a rightmost pixel of the specific image pixel in the first row as a leftmost edge and a rightmost edge of a first specific image range; and defining a second specific image range in a second row of the image, which is next to the first row. Column positions of a leftmost edge and a rightmost edge of the second specific image range are respectively the same with column positions of the leftmost edge and the rightmost edge of the first specific image range. Via this method, the determining for the specific image pixels is more accurate.

Abstract: A position detecting system with a position information providing apparatus, a transceiver, and a processor. The position information providing apparatus comprises a light emitting-out side having at least one position information region distributed on an outer surface of the light emitting-out side. The position information region comprises materials which are distributed on the outer surface and provide the position information. The light has position information from the position information region when the light emits out from at least part of the light emitting-out side. The transceiver receives the light with the position information. The processor determines a relative position between the transceiver and the position information providing apparatus according to the position information received by the transceiver.

Abstract: A distance measurement system and method are provided. The distance measurement method first projects a light beam with a speckle pattern to reference planes and an object to allow the reference planes and a surface of the object each have an image of the speckle pattern, the speckle pattern having a plurality of speckles. Next, images of the speckle pattern reflected by the reference planes are captured to generate reference image information, and an image of the speckle pattern reflected by the surface of the object is captured to generate an object image information. A processing module which may be a processing software can compare the object image information with the reference image information to obtain several similarity scores. If the most the most similarity score is greater than a threshold value, the processing module identifies the corresponding reference plane, thereby computing the position of the object.
