UVR Lab. was formed in Feb. 2001 at GIST to study and develop “Virtual Reality in Smart computing environments” that process multimodal input, perceive user’s intention and emotion, and respond to user’s request through Augmented Reality. Since 2012, UVR Lab moved to KAIST GSCT and restarted with a theme of “FUN in Ubiquitous VR.”

■ 주제: Illuminant Analysis for Plausible Lighting in Augmented Reality


■ 연사: Seokjun Lee, Senior Researcher, Daegu Digital Promotion Agency


■ 일시: 2018 9월 5일 (낮 12~


■ 장소: KAIST KI빌딩 4층 CUBE CYAN (D403)


■ 주관: KAIST KI-ITC 증강현실연구센터(ARRC)


■ 후원KAIST CT대학원한국HCI학회 DCH(디지털문화유산연구회대한전자공학회 AH(증강휴먼연구회


■ 요약 :


This talk presents a practical method for estimating real light sources in real environments,

using a mirror sphere placed on a known natural marker.

For the stable results of static lighting, camera takes the multiple images around the sphere and

estimate the principal light direction of the vector clusters for each light source.

This method also estimate the dynamic illuminant for dynamic changes of the scene illumination,

and augment the virtual objects onto the real image with the proper shading and shadows.

Some experimental results show that the presented scheme produces realistic AR visualization in real time.
