  1. 1. Laser dazzling of CMOS imaging sensors using amplitude modulated and continuous wave lasers

    University essay from Umeå universitet/Institutionen för fysik

    Author : Johan Fjellström; [2023]
    Keywords : ;

    Abstract : Protecting sensitive information is important, especially in defence applications. As cameras become more common, developing countermeasure systems that limit the information gathering capabilities of imaging sensors would be beneficial. READ MORE

  3. 2. Review and Design of DC Electrical Field Measurement Systems and Related Developments : For Measurements Around HVDC Cable Terminations

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Emil Bergvall; [2023]
    Keywords : DC Field Probe; Measurement Systems; Electric Fields; Cable Termination; Ion Drift; Conductivity; HVDC; Field Mill; Field Simulations; Positioning System; MEMS; Electro-Optics; DC Fält Prob; Mätsystem; Elektriska Fält; Kabelavslut; Jondrift; Ledningsförmåga; HVDC; Fältkvarn; Fält Simulationer; Positioneringsystem; MEMS; Elektro-Optik;

    Abstract : With power generation and consumption placed further away from each other, with for example increased offshore power production, the need for HVDC transmission systems increases. As voltage levels in the HVDC transmission system are raised, the losses can be decreased, enabling efficient power transfer over longer distances. READ MORE

  4. 3. Rolling shutter in feature-based Visual-SLAM : Robustness through rectification in a wearable and monocular context

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Caspar Norée Palm; [2023]
    Keywords : SLAM; rolling; shutter; rectification; ORB-SLAM3; monocular; camera; compensation; visual; odometry; simultaneous; localization; mapping;

    Abstract : This thesis analyzes the impact of and implements compensation for rolling shutter distortions in the state-of-the-art feature-based visual SLAM system ORB-SLAM3. The compensation method involves rectifying the detected features, and the evaluation was conducted on the "Rolling-Shutter Visual-Inertial Odometry Dataset" from TUM, which comprises of ten sequences recorded with side-by-side synchronized global and rolling shutter cameras in a single room.

  5. 4. Verification Method for Time of Capture of a Rolling Shutter Image

    University essay from Linköpings universitet/Databas och informationsteknik

    Author : Filip Johansson; Alexander Johansson; [2023]
    Keywords : Verification method; rolling shutter; image timestamp; camera systems; mapping study; automotive;

    Abstract : Modern automotive systems increasingly depend on camera sensors to gather safetycriticaldata used in driver-assisting features of the system. These features can consist offor example, lane-keeping assist and automatic braking where the sensors register objectswithin certain distances. READ MORE

  6. 5. Automatic Calibration of Camera Parameters : A Steppingstone to Analysing Videos

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Wilma Hallén; [2022]
    Keywords : Smartphone; Video stabilisation; Calibration;

    Abstract : The smartphone is commonly used for image and video capture. Due to the lightweight of the smartphone, small handshakes are noticeable in recorded videos. The image sensors in smartphones are typically CMOS, which introduces rolling shutter artefacts. Stabilisation is introduced to minimise the effects of the camera movement and artefacts. READ MORE
