Title:
PROJECTION SYSTEM, SEMICONDUCTOR INTEGRATED CIRCUIT, AND IMAGE CORRECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2015/125401
Kind Code:
A1
Abstract:
This projection system (100) is provided with: a projection device (102) which projects onto an object a pattern light which shows a pattern image which encodes projection coordinates defined in a projection coordinate system; an imaging device (101) which images the pattern light and generates a first imaged image; and an image correction device (104) which, on the basis of the first imaged image, generates first coordinate conversion information which associates projection coordinates with imaging pixel coordinates defined in an imaging coordinate system of the imaging device, and uses the first coordinate conversion information to correct a previously prepared projection image.
