摘　　要：针对AGV全自动视觉引导小车设计了一种基于FPGA的颜色识别系统。该系统使用OV7670对于路面数据进行采集,FPGA颜色识别系统将对BRAM进行操作,读取BRAM的数值到SRAM中,使用阈值判定法对于识别的物体进行颜色识别。该系统能适应AGV运输小车的高时序性要求的特性,提升了小车在运行时的精度与速度,具有广泛的应用前景。A color recognition system based on FPGA is designed for AGV automatic vision guidance vehicle. The system uses OV7670 to collect road surface data, and the FPGA color recognition system will operate the BRAM, read the BRAM value into SRAM, and use the threshold judgment method to identify the color of the object. The system can adapt to the characteristics of high time sequence of AGV transport vehicles, improve the accuracy and speed of the car in operation, with a wide range of application prospects.
