Title: Method and apparatus for optical sensing
Inventor: MAHMOUD FARHADIROUSHAN
IPC: G01H9/00
Filed: 2016-03-07
Abstract: Embodiments of the invention provide an improved optical fiber distributed acoustic sensor system that makes use of a specially designed optical fiber to improve overall sensitivity of the system, in some embodiments by a factor in excess of 10. This is achieved by inserting into the fiber weak broadband reflectors periodically along the fiber. The reflectors reflect only a small proportion of the light from the DAS incident thereon back along the fiber, typically in the region of 0.001% to 0.1%, but preferably around 0.01% reflectivity per reflector. In addition, to allow for temperate compensation to ensure that the same reflectivity is obtained if the temperature changes, the reflection bandwidth is relatively broadband i.e. in the region of +/- 3nm from the nominal laser wavelength. In some embodiments the reflectors are formed from a series of fiber Bragg gratings, each with a different center reflecting frequency, the reflecting frequencies and bandwidths of the gratings being selected to provide the broadband reflection. In other embodiments a chirped grating may also be used to provide the same effect. In preferred embodiments, the reflectors are spaced at half the gauge length i.e. the desired spatial resolution of the optical fiber DAS.

Title: Photorealistic three dimensional texturing using canonical views and a two stage approach
Inventor: Tomas Francisco Vicente
IPC: G06T15/04
Filed: 2019-02-05
Abstract: Images of various views of objects can be captured. An object mesh structure can be created based at least in part on the object images. The object mesh structure represents the three-dimensional shape of the object and includes a mesh with mesh elements. The mesh elements are assigned views first from a subset of views to texture large contiguous portions of the object from relatively few views. Portions that are not textured from the subset views are textured using the full set of views, such that all mesh elements are assigned views. The views first assigned from the subset of views and the views then assigned from the full plurality of views can be packaged into a texture atlas. These texture atlas views can be packaged with mapping data to map the texture atlas views to their corresponding mesh elements. The texture atlas and the object mesh structure can be sent to a client device to render a representation of the object. The representation can be manipulated on the client device in an augmented reality setting.

Abstract: The present invention provides a method and a system for location of a high slope collapse area. Firstly, slope images in a long time series are obtained 101, the slope images in the long time series are composed 102 into a two-dimensional slope deformation graph, and an area with the maximum deformation in the two-dimensional slope deformation graph is selected 103 as a deformation area. A deformation region is obtained and overlapping 106 in the slope images the time series data is used to create a monitoring line area. Finally, monitoring points are selected from the monitoring line area to determine the location of the high slope collapse according to a coordinate change of each monitoring point in the slope images in the long time series. The intention is to monitor accurately and reliably areas of high slope collapse, particularly to identify rapid movement of a slope.
