A Simplified System Model for Optical Camera Communication
2021 IEEE/CIC International Conference on Communications in China (ICCC), 2021Data rate and communication distance are two important criteria for measuring the performance of optical camera communication (OCC) systems. Intensive researches have been made to find possible solutions to improve these two performance indicators. However, most existing literature either provides solutions which closely related to the experimental ...

Radiometric and geometric camera model for Optical Camera Communications
2015 Seventh International Conference on Ubiquitous and Future Networks, 2015When an object projected on a camera, the shape of the projected object image is governed by the relative position and orientation between object and camera. On the other hand, object radiance, viewing angle and distance at the time of taking picture determine the image brightness of an object.

Synchronization issue for optical camera communications
2015 Seventh International Conference on Ubiquitous and Future Networks, 2015When mentioning about camera, we just think about the picture characteristics such the quality, the resolution. Besides, it will be also the promising technique for communication issue which can be called as optical wireless communication (OWC). The research about OWC has been pushed from these years.

Experimental Characterization of Fiber Optic Lighting - Optical Camera Communications
2021 IEEE 32nd Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2021In this paper, we study the novel idea of fiber optic lighting - optical camera communications. We carry out analyses of the proposed scheme employing a light emitting diode (LED) illuminated plastic optical fiber (POF) and a rolling-shutter-based camera as the transmitter and the receiver (Rx), respectively in an indoor static environment.

Practical design of Screen-to-Camera based Optical Camera Communication
2015 International Conference on Information Networking (ICOIN), 2015This paper introduces the Optical Camera Communication (OCC) based on Computer Vision. The practical issues of implementation of the asynchronous communication based Screen-to-Camera are performed. The asynchronous scheme proposed by our previous work is modified to be simple, suitable and reliable in order to apply in case of heterogeneous frame rate ...

Invisible embedded techniques for optical camera communications
2017 International Conference on Information Networking (ICOIN), 2017Optical camera communications (OCC) is a promising technology due to the development and commercialization of camera. Similarly with visible light communication (VLC), OCC will decode the signal from light source by invisibility or visibility. The invisibility technique for OCC is based on the over frequency response or less sensitive color of human ...

Performance of rolling shutter and global shutter camera in optical camera communications
2015 International Conference on Information and Communication Technology Convergence (ICTC), 2015Optical Camera Communication (OCC) is considered as an extension of IEEE 802.15.7 specification by same communication channel. Different with another technique, Optical Camera Communication used image sensor for receiver, so the characteristic of image sensor will effect on the operation and performance.

Applying NOMA to Undersampled Optical Camera Communication for Vehicular Communication
2018 Eleventh International Conference on Mobile Computing and Ubiquitous Network (ICMU), 2018Visible Light Communications (VLC) is being developed as an alternative to radio frequency (RF) communication for vehicular applications. It has the advantages of high signal-to-noise ratio (SNR), limited interference due to line-of-sight transmission and dual use of existing hardware (LED lights and cameras) on most modern vehicles.
