Title: Cross-source point cloud registration
Inventor: Xiaoshui Huang
IPC: G06T19/20
Filed: 2017-09-05
Abstract: Method comprising: identifying first and second structures in a scene from first and second 3D coordinates (point cloud) produced by first and second 3D scene capture devices; deriving 3D structure coordinates of each of the first structures and each of the second structures; registering the first 3D structure coordinates with the second 3D structure coordinates by: determining correspondence between the first and second 3D structure coordinates; determining and applying a geometric transformation between the first 3D structure coordinates and second 3D structure coordinates. Point cloud topology may be segmented into voxels whose centres or corner points (vertices) may form the structure coordinates. Registration may be iterative until an energy function, optimised using tensors and comprising a structural similarity score and pixel-wise refinement score, converges to an optimal value. Similarity values of co-ordinate triplets may be selected using wide baseline strategy. Transformation may be affine transformation, rotation based on matched point pairs, scale estimation, translation based on mean points. Scene scanning may be LIDAR (Light Detection and Ranging), structure from motion (SFM), simultaneous localisation and mapping (SLAM). 3D model scene may be constructed.

Title: Spectrally programmable memristor
Inventor: Samuel James Maguire-Boyle
IPC: G11C13/00
Filed: 2015-04-23
Abstract: A memristor element is used to create a spectrally programmable optical device. An electromagnetic field is applied across the memristor element in order to alter its spectral properties. In turn, the spectral properties of the electromagnetic radiation optically interacting with the memristor element are also altered. This alteration in spectral properties allows the memristor to be "programmed" to achieve a variety of transmission/reflection/absorption functions.

Title: Laser system
Inventor: GARETH THOMAS MAKER
IPC: H01S3/13
Filed: 2017-10-13
Abstract: A laser system 1 comprises two phase-locked solid-state laser sources 2, 3 for example, Ti: sapphire lasers may be may be continuously pumped at 532 nm sources 4, 5. The laser system 1 can be phase-locked at a predetermined offset between the operating frequencies of the lasers. This is achieved with high precision while exhibiting both low noise and high agility around the predetermined offset frequency. A pulse generator 14 can be employed to generate a series of optical pulses from the laser system, the number, duration and shape of which can all be selected by a user. A phase-lock feedback loop provides a means for predetermined frequency chirps and phase shifts to be introduced throughout a sequence of generated pulses. The laser system can be made highly automated. The above features render the laser system ideally suited for use within coherent control two state quantum systems, for example atomic interferometry, gyroscopes, precision gravimeters gravity gradiometers and quantum information processing and in particular the generation and control of quantum bits.
