1. 1. PTZ Camera Tampering Correction Using IMUs

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Ludvig Hansson; Måns Lindeberg; [2022]
   Keywords : Technology and Engineering;

   Abstract : The Pan-Tilt-Zoom (PTZ) camera is a type of camera that covers large areas, up to 360°, in addition to zoom. Some of these cameras are susceptible to tampering, which means that an additional angle measurement feedback is necessary to detect such attempts. This thesis has evaluated the possibility of using MEMS-based IMUs to solve this problem. READ MORE

3. 2. Modelling the Shuttle Movement of a Seismic Airgun

   University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

   Author : Ludvig Lindeberg; [2019]
   Keywords : seismic airgun; euler equations; finite difference; numerical analysis;

   Abstract : A provably stable and high-order accurate semi-discrete finite difference scheme modeling the shuttle movement of a seismic airgun is derived using the SBP-SAT method. The one dimensional airgun model studied consists of two pressurized compartments separated by a moving shuttle. READ MORE
