基于现场可编程门阵列的水果识别系统设计OA北大核心CSTPCD

To address problems of high latency and high cost in most fruit identification systems,this study proposes a fruit recognition system based on the field programmable gate array(FPGA).The overall hardware design includes image acquisition,detection and recognition and display modules.In the software part,fruit images are stored in the double-data-rate3(DDR3)controller module through the image acquisition platform,and undergo image grayscale processing.Furthermore,a creative approach is introduced,using the background and the frame differ-ence method for segmentation of fruit images.By integrating fruit color and geometric features,recognition of fruit quantity,color,and species was achieved.The fruit identification system was tested under different lighting condi-tions and intensities.The experimental results show that the method has an average accuracy of 93.25%for the recognition of fruits,a recognition speed of approximately 16.67 ms,and the FPGA hardware design consumption rate of only 28.02%,which can meet the real-time requirements of fruits recognition.
