Patent number: 8366003Abstract: In an illustrative implementation of this invention, an optical pattern that encodes binary data is printed on a transparency. For example, the pattern may comprise data matrix codes. A lenslet is placed at a distance equal to its focal length from the optical pattern, and thus collimates light from the optical pattern. The collimated light travels to a conventional camera. For example, the camera may be meters distant. The camera takes a photograph of the optical pattern at a time that the camera is not focused on the scene that it is imaging, but instead is focused at infinity. Because the light is collimated, however, a focused image is captured at the camera's focal plane. The binary data in the pattern may include information regarding the object to which the optical pattern is affixed and information from which the camera's pose may be calculated.Type: GrantFiled: July 16, 2010Date of Patent: February 5, 2013Assignee: Massachusetts Institute of TechnologyInventors: Ankit Mohan, Ramesh Raskar, Shinsaku Hiura, Quinn Smithwick, Grace Woo

Patent number: 6471126Abstract: An invisible symbol reading apparatus includes a heating unit for heating an invisible symbol formed on a sample and containing a material which emits infrared light when heated, a detecting unit for detecting infrared light emitted from the invisible symbol, and an arithmetic operation unit for binarizing a detection signal from the detecting unit. The arithmetic operation unit calculates a differential coefficient of the detection signal, that corresponds to a position on the sample. On the basis of upper and lower threshold values set for the differential coefficient, the arithmetic operation unit determines a maximum value of the differential coefficient in a region exceeding the upper threshold value and a minimum value of the differential coefficient in a region smaller than the lower threshold value. The arithmetic operation unit binarizes the detection signal by using the maximum or minimum value as a leading or trailing edge of a binary function.Type: GrantFiled: January 2, 2001Date of Patent: October 29, 2002Assignee: Kabushiki Kaisha ToshibaInventors: Taeko I.

Methods and apparatus for scan pattern selection and selective decode inhibition in barcode scanners
Publication number: 20020148898Abstract: Methods and apparatus for switching between scan patterns produced by a barcode scanner and for switching between allowing and inhibiting decoding of barcodes are disclosed. Depending on the position of a multiposition switch controlled by an operator, the scanner produces an omnidirectional scan pattern and immediately decodes barcodes falling within the field of view of the scanner, produces a single line scan pattern but inhibits decoding of barcodes until the switch is moved to a position to select allowing decoding of barcodes, or produces a single line scan pattern and immediately decodes barcodes falling within the field of view of the scanner. If the scanner has been set to decode barcodes using a single line scan pattern, a delay is imposed between the time the switch is set to select producing an omnidirectional scan pattern and the time at which the scanner begins to produce the omnidirectional scan pattern.Type: ApplicationFiled: April 17, 2001Publication date: October 17, 2002Applicant: NCR CorporationInventors: David Lee Gregerson, Frank Stanley Hannah, William Martin Belknap, James Brian McCord -
