1. 1. 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.

3. 2. 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

4. 3. 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

5. 4. Evaluation of Monocular Visual SLAM Methods on UAV Imagery to Reconstruct 3D Terrain

   University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

   Author : Fredrik Johansson; Samuel Svensson; [2021]
   Keywords : Computer vision; Simultaneous Localization and Mapping; SLAM; Visual SLAM; V-SLAM; Monocular; UAV; Drone mapping; D reconstruction of terrain; Point cloud;

   Abstract : When reconstructing the Earth in 3D, the imagery can come from various mediums, including satellites, planes, and drones. One significant benefit of utilizing drones in combination with a Visual Simultaneous Localization and Mapping (V-SLAM) system is that specific areas of the world can be accurately mapped in real-time at a low cost.

6. 5. Simulation of Optical Aberrations for Comet Interceptor’s OPIC Instrument

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Maximilian Bührer; [2020]
   Keywords : simulation; camera; lens effects; optical aberrations; optics; ray tracing; sensor noise; coma; astigmatism; chromatic aberration; motion blur; rolling shutter; CMOS; CCD;

   Abstract : In space exploration optical imaging is one of the key measurements conducted, with a vast majority of missions heavily relying on optical data acquisition to examine alien worlds. One such endeavor is ESA’s F-class mission Comet Interceptor, a multi-element spacecraft expected to be launched in 2028. READ MORE
