Computational swept volume light painting via robotic non-linear motion

摘要

Light painting is a photography technique in which light sources are moved in specific patterns while being captured by long exposure. The movements of lights will result in bright strokes or selectively illuminated and colored areas in the scene being captured, thus decorating the real scene with special visual effects without the need for post-production. Light painting is not only a popular activity for hobbyists to express creativities, but also a practice for professional media artists and photographers to produce aesthetic visual arts and commercial photography. In conventional light paintings, the light sources are usually flashlights or other simple handheld lights made by attaching one or multiple LEDs to a stick or a ring. The patterns created are limited to abstract shapes or freehand strokes.
