Design of Color Recognition System Based on FPGA

Color recognition plays an important role in Machine Vision and Artificial Intelligence. In this article, a system based on FPGA applying to image acquisition, storage, display and color recognition is designed mainly to complete the recognition and calibration of fixed colors. Color images are captured by the analog camera in the system, which are decoded into standard YCbCr 4:2:2 data streams by AD chip. Then data streams are converted to the data of RGB video format by performing color space conversion. In the RGB color space, the color recognition method is proposed to identify the target color and calibrate on the display device. The experimental results demonstrate that the method can effectively achieve the identification of certain kinds of colors.
