Abstract
The present invention discloses a color contrast enhanced rendering method, device and system suitable for an optical see-through head-mounted display. The method includes: (1) acquiring a background environment in real time to obtain a background video and performing Gaussian blur and visual field correction on the video; (2) converting an original rendering color and a processed video color from an RGB color space to a CIELAB color space scaled to a unit sphere range; (3) finding an optimal rendering color based on the original rendering color and the processed video color in the scaled CIELAB space according to a set color difference constraint, a chromaticity saturation constraint, a brightness constraint and a just noticeable difference constraint; and (4) after converting the optimal rendering color back to the RGB space, performing real-time rendering by using the optimal rendering color of the RGB space. The method is widely applied and capable of obviously improving the discrimination between a virtual content and a background environment and supporting various virtual scenes and background environments without a pre-preparation process.
