   Nyckelord :Infrared imagery; VIS; NIR; LWIR; geoprocessor; geolocation; quaternions; Aistech Space; image processing; ORB; RANSAC; Sentinel; Landsat; Infraröda bilder; VIS; NIR; LWIR; geoprocessor; geolokalisering; kvarternioner; Aistech Space; bildbehandling; ORB; RANSAC; Sentinel; Landsat;

   Sammanfattning : This thesis presented an overview of the development of a geolocating algorithm as part of a geoprocessor for raw satellite imagery. This algorithm was devised for and limited by the specifications of a state-of-the-art multispectral telescope designed by Aistech Space, hosted onboard the Guardian spacecraft, which will observe Earth through the visible, near infrared, and thermal infrared bands of the electromagnetic spectrum.

3. 2. Branching Avoidance in Kinematic Image Space for Linkage Synthesis

   M1-uppsats, Lunds universitet/Matematik LTH

   Författare :Adam Nilsson; [2013]
   Nyckelord :Linkage Synthesis; Quaternion; Dual Quaternion; Constraint Manifold; Four-Bar Linkage; Technology and Engineering; Mathematics and Statistics;

   Sammanfattning : We consider a finite position synthesis and branching avoidance of four-bar linkages based on kinematic theory derived from dual quaternions. The branching defect is defined as a situation where all specified task positions are not connected by a continuous motion of the linkage end effector. LÄS MER
