Projection mapping merges the physical and digital worlds seamlessly through projected imagery. It has
been widely applied in media art installations and interactive artworks. However, physical surfaces
around us are unsuitable for projection mapping since projectors are originally designed to display images
on a uniformly white, planar screen. Consequently, the image quality of a projection mapping gets
degraded. This article introduces technical solutions to alleviate image quality degradation. Specifically,
it explains the details of geometric correction, defocus blur compensation, radiometric (or color) compensation,
and shadow removal techniques. It also shows the experimental results of these technologies
to demonstrate their feasibility.
