Abstract: A new colour identification system and the hardware and software applied to it are introduced in this paper. Also, the experimental results related to the system are presented. The CCD device, a colour sensor, is adopted for this system and takes advantage of the high sensitivity, high steady and flat spectral response as well as the low noise of the sensor. As a consequence, it is realized that colour identification and measurement can reach relatively high accuracy and speed in this system. It proves that the device can be used as a part of the colour vision for artificial intelligence robots.
