Patent CA-2707176-A1 (CA)
Inventor: ARIAS ESTRADA MIGUEL OCTAVIO
IPC: G06T11/00
Filed: 2007-11-28
Abstract: The present invention comprises a method and an apparatus for three-dimensional modelling using the principle of stereo vision with an integrated lighting system used for restoring depth without prior data on the surface reflection.  The method includes several initial steps using stereo and radiometric calibration and processes of rectification with a view to obtaining precise results. In addition, an active stereo technique is applied in order to restore dense depth maps from a simple pair of stereo images. This technique is a combination of conventional approaches and stereo photometry and is based on the reflection reciprocity property which considers an arbitrary surface distribution of the reflection. This particular property is achieved if the object to be restored is acquired in the specific lighting conditions provided by the invention. The active stereo technique is followed by a process of in-depth map calibration. The method also includes a procedure for image acquisition for obtaining the sets of images required for calibration, rectification and three-dimensional restoration processes.  The apparatus for stereo acquisition of images comprises internal light sources which are automatically communicated by a lighting control to ensure the reciprocity property, a stereo camera head made up of the optics required for acquiring reciprocal stereo images and a PC compatible interface. Positions of external light sources can be considered as an extension of this apparatus. The method and apparatus can be extended to other cameras or light source configurations for acquiring large objects and/or multiple points for view acquisition. This invention is potentially quicker than other 3-D scanners or 3-D restoration systems since it requires only two images in order to obtain deep models of objects with an arbitrary distribution of surface reflection such that, the system is useful in a wide range of applications such as metrology, quality control and medical and dynamic three-dimensional modelling.

Abstract: A method for manufacturing a one-piece shoe shell of a skate with different widths having acts of forming a shoe shell 10 with a rudimentary mold assembly, ejecting the shoe shell 10 from the rudimentary mold assembly and adjusting a width of the sole 11 of the shoe shell 10 before the shoe shell hardens. The sole 11 of the shoe shell 10 has at least one adjusting portion 14 to allow the sole 11 to expand or be compressed. With the acts, each size of the shoe shell 10 needs only one rudimentary mold assembly that has complex structure and high cost to substantially form a basic shape of the shoe shell and multiple shaping molds of different widths that have simple structure and low cost are prepared to further adjust widths of the shoe shell 10.  Consequently, total cost for manufacturing the shoe shell 10 with different widths is effectively lowered.

Abstract: Methods and devices for use in gathering and analyzing data from a corpus of documents. A corpus of documents is initially scanned for words that qualify as entities according to user defined criteria. Multiple counters track the number of documents which mention specific entities. A database of entities mentioned in the documents is maintained and an entry for each entity in the corpus is placed in the entity database.  The results are then presented to a user in a spiral form with the most important entity at the center of the spiral. The importance of an entity may be determined by either how many entities it is connected to or how many documents mention that entity. A connection exists between two entities if they are both mentioned in at least one document and the more documents mention two specific entities at the same time, the stronger the connection between those two specific entities. The result presentation to the user is capable of also visually representing connections between entities by connecting connected entities with lines. The strength of a connection can also be represented with the width of the line connecting two entities.
