Color contrast enhanced drawing method, device and system suitable for optical transmission type head-mounted display

摘要: The invention discloses a color contrast enhanced drawing method, device and system suitable for an optical transmission type head-mounted display, the method comprises steps: (1) collecting abackground environment in real time so as to obtain background video, carrying out Gaussian blur visual field correction of video; (2) converting original theprocessed video from RGB space CIELAB scaled unit sphere range; (3) searching optimal based on processed videocolor according set difference constraint, chromaticity saturation brightness constraint minimum constraint; (4) back space, performing real-time by utilizing space. is wide application range, discriminationbetween virtual content can be remarkably improved, various scenes environments are supported, pre-preparation process not needed.
