Title (up) A preliminary investigation of Luojia-1 night-time light imagery Type Journal Article
Year 2019 Publication Remote Sensing Letters Abbreviated Journal Remote Sensing Letters
Volume 10 Issue 6 Pages 526-535
Keywords Remote Sensing; Instrumentation
Abstract Launched on 2 June 2018, Luojia-1 satellite records night-time light imagery at 130 m resolution, which is higher than most of the existing night-time light images to date. This study evaluated radiometric and spatial properties of the Luojia-1 satellite imagery for cities of Los Angeles, Wuhan and Rome as well as the change detection capability for Zunyi city. For the radiometric property, the analysis shows that the Luojia-1 images correlate well with the radiance of the Visible Infrared Imaging Radiometer Suite (VIIRS)’s Day and Night Band (DNB), and that the Luojia-1 images have a wider range of radiance values, as well as higher radiance values (e.g., 40%–90% higher) than the VIIRS DNB images. Using wavelet decomposition and change detection analysis to evaluate spatial property and change detection capability, it was found that the Luojia-1 images provide abundant spatial detail information, with about 20%–54% energy of wavelet component of the images stored in 100–400 m resolutions, and they can help to track the electrification of new roads and buildings at a fine resolution. This study shows that the Luojia-1 images are an effective data source for analysing spatiotemporal distribution of night-time light and its associated socioeconomic attributes.

Title (up) A Research on the Improvement of Visibility Using Low Deck Lighting in Bad Weather Type Journal Article
Year 2020 Publication Journal of the Korean Institute of Electrical and Electronic Material Engineers Abbreviated Journal
Volume 33 Issue 3 Pages 186-193
Keywords Lighting
Abstract We investigate a fog-detection CCT control system using low deck lighting as a solution to the forward visibility of pole-type street lamps employed on existing roads. The lighting standards were met with a light source that has less compared with those of pole-type street lamps. The results show that the transmission rate was increased by changing the color temperature by automatically recognizing fog in bad weather and minimizing the phenomenon of lighting. In addition, it was allowed to create a safer and more comfortable driving environment for drivers owing to flicker or light pollution of existing pole-type street lamps. As a result, if lighting is used at a lower level than pole-type street lamps, the accident rate caused by securing the driver's forward visibility can be reduced sharply and existing problems can be resolved.

Title (up) A Research on Visual Performance at Different Ages Depending on Color Temperature of Headlights Type Journal Article
Year 2017 Publication Journal of the Korean Institute of Illuminating and Electrical Installation Engineers Abbreviated Journal
Volume 31 Issue 8 Pages 40-48
Keywords Lighting
Abstract Under night-time driving conditions, both cones and rods in eye’s retina simultaneously act to influence mesopic vision in two areas: central and peripheral visions. However, as people age, the amount of light received as well as the color temperature perceived by the human eyes also change. This research, through simulations and scaled down experiments with various headlight color temperatures and two levels of fixed brightness, deals with differences in ability to detect and identify obstacles by the subjects in their 20’s and 50’s.

According to the results obtained from the experiments on peripheral vision, subjects in their 20’s detected the obstacles more quickly at the combined color temperature of 3,000K+4,500K than at the single color temperature of 4,500K, and likewise at 3,000K+5,500K than at 5,500K; this tendency was significantly more noticeable for the subjects in their 50’s. As for the central vision, the results showed that there were no significant differences due to color temperature between the subjects in their 20’s and those in their 50’s. Moreover, the landolt ring experiment conducted under low luminance yielded higher percentage of correct answers at combined color temperatures.
