“…A precise and robust distance measurement using frequency-domain analysis based on a stereo camera from the analysis of captured images was conducted in Ref. [27]. Here, distance information is calculated using the baseline of two monocular cameras, the focal length, and the pixel disparity that can be calculated directly through the phase of the frequency domain.…”

Localization has become an important aspect in a wide range of mobile services with the integration of the Internet of things and service on demand. Numerous mechanisms have been proposed for localization, most of which are based on the estimation of distances. Depending on the channel modeling, each mechanism has its advantages and limitations on deployment, exhibiting different performances in terms of error rates and implementation. With the development of technology, these limitations are rapidly overcome with hybrid systems and enhancement schemes. The successful approach depends on the achievement of a low error rate and its controllability by the integration of deployed products. In this study, we propose and analyze a new distance estimation technique employing photography and image sensor communications, also named optical camera communications (OCC). It represents one of the most important steps in the implemented trilateration localization scheme with real architectures and conditions of deployment which is the second our contribution for this article. With the advantages of the image sensor hardware integration in smart mobile devices, this technology has great potential in localization-based optical wireless communication

“…One of the biggest advantages of dealing with near-crashes is that they are much more frequent than crash events (see the classic 'safety pyramid' introduced by Hydén [6]), resulting in shorter observation times to collect enough data for statistical analysis, whereas the biggest disadvantage is that it may be difficult or expensive to gather reliable data. However, recent development in sensing and ITS technologies highly improved the availability and accuracy of traffic measures [7,8], especially in highways [9][10][11], and the so-called 'big data' can be exploited for a cleaner, more efficient, but also safer transport system [12].…”

“…It is, therefore, of interest to investigate solutions that can obviate the use of a LiDAR for ranging in real‐time driving. Stereo vision is an alternative for distance estimation [3]. Although it is cost‐effective, stereo processing is computationally very intensive and not feasible for real‐time applications.…”
