摘　　要：传统颜色辨识系统需要白平衡调整,引入了人为误差,造成辨别精度较差。介绍了一种改进型颜色辨识方案,采用TCS3200D颜色传感器将颜色信号转换为数字信号后直接送至AT89C52单片机处理,硬件电路简单,在基本型软件算法的基础上设计了改进型软件算法流程,避免了白平衡调整引入的人为误差,有效提高了辨识精度。实验结果表明:系统对不同颜色辨识速度快、精度高,可广泛应用于各种需要对颜色成分进行分析、辨识的行业。Traditional color recognition systems need white balance adjustment which introduces human error,resulting in poor distinguish accuracy.A kind of improved color recognition program is introduced.TCS3200D color sensor converts the color signals to digital signal and sent directly to the AT89C52 microcontroller processing with simple hardware circuit.An improved software algorithm process is designed on the basis of the basic software algorithms to avoid human error introduced by the white balance adjustment,effectively improves the recognition precision.Experimental result shows that the system has fast identification speed of different colors,high precision,and can be widely used in a variety of color composition analysis and the identification industry.
