In recent years,modern industrial production technology has developed rapidly,and the degree of mechanization in various industries has continued to increase.Industrial products play an increasingly important role in our lives,and the quality requirements of these industrial products are increasingly stringent,especially in terms of the appearance quality of the product.However,with regard to the current existing product quality inspection methods,the detection methods are too simple and the analysis accuracy is not high enough.These are all important factors that restrict the development of product quality inspection.Therefore,an efficient and reliable color analysis and processing system is urgently needed in the industry.Based on the in-depth study of the analysis ideas and experiments of color analysis at home and abroad,this paper compares the bilinear interpolation algorithm and the gradient detection interpolation algorithm,and optimizes the bilinear interpolation algorithm to facilitate different data formats of image;In order to intuitively perform color perception,this paper analysises different color models,transforms RGB color space to HSV color space,and analysises the gray histogram algorithm;On these basis,combined with image processing technology,color basic theory,this paper proposes a digital image color selection analysis system based on FPGA.The system includes image acquisition,image format conversion,image buffering,color analysis and result display units.Using the relevant logic operation and color processing algorithm,the RGB component values of each pixel of the digital image are extracted and compared with the standard color components,and the RGB component histogram is displayed to determine whether the product is qualified.The result is output to the VGA screen through the VGA interface.Images processed by color analysis algorithms can be clearly distinguished.By analyzing multiple sets of product images,the digital image color selection system can perform image acquisition processing within milliseconds,and the gray histogram can intuitively judge the product,so this syst:em meets the expected design goals.This ystem can be widely used in various industries,and has certain practical,value.
