Experimental Demonstration of 32‐PAM Optical Camera Communication Using a Low Cost and a High Cost Camera

IET Optoelectronics
This work demonstrates experimentally the feasibility of using up to 32‐PAM in rolling shutter based optical camera communication (OCC). Two different cameras have been used for OCC performance comparison, namely, a low‐cost Pi Camera V2.1 and a higher ...

Demonstration of symbol timing synchronization for rolling shutter-based optical camera communication.

Optics Express
Optical camera communication (OCC) provides license-free communication channels without radio waves. The rolling shutter mechanism is expected to enhance the capacity of wireless links in OCC.

Water-to-air unmanned aerial vehicle (UAV) based rolling shutter optical camera communication (OCC) system with gated recurrent unit neural network (GRU-NN).

Optics Express
Underwater sensors and autonomous underwater vehicles (AUVs) are widely adopted in oceanic research activities. As the number of underwater sensors and AUVs is growing quickly, the bandwidth requirements are increasing accordingly.

Calibration and In-flight Performance of DART’s Didymos Reconnaissance and Asteroid Camera for OpNav (DRACO)

The Planetary Science Journal
The Didymos Reconnaissance and Asteroid Camera for OpNav (DRACO) was the only instrument on board NASA’s Double Asteroid Redirection Test spacecraft. DRACO had a 2628.326 mm focal length Ritchey–Chrétien telescope with a 208.28 mm aperture and a 0.29 ...

3D Vision Geometry for Rolling Shutter Cameras

, 2019
De nombreuses caméras CMOS modernes sont équipées de capteurs Rolling Shutter (RS). Ces caméras à bas coût et basse consommation permettent d’atteindre de très hautes fréquences d’acquisition. Dans ce mode d’acquisition, les lignes de pixels sont exposées séquentiellement du haut vers le bas de l'image. Par conséquent, les images capturées alors que la

Multiview Varieties of rolling Shutter Cameras

This study looks at the rolling shutter camera model and how pictures taken by moving cameras of this model can be used in 3D reconstruction. Unlike how the widely used pinhole camera model takes the entire picture in one go, a rolling shutter camera takes a picture by scanning each pixel line individually.
