Research on the Color Detection of LCD Instrument Panel Based on Machine Vision

Abstract

The research focuses on the color detection of automobile LCD instrument panel. In order to detect the color of indicating symbol and LCD-screen simultaneously, which the former one is reflector and the later one is self-illuminant. The LCD computer screen and projector apparatus are used in the experiment to represent the reflector and self-illuminant, and then, we analyze their color feature differences in machine vision system. The study shows that the vision features of reflective colors and self-luminous colors in machine vision system are approximately same. However, there are a few differences in their vision features, which will impact on the detective methods designing.
