基于特殊RGB 排列的彩色LED 阵列计算鬼成像

Low quality of images is a critical problem that inhibits the application of computational ghost imaging CGI technology Therefore a special RGB Red Green Blue arrangement is designed for the chromatic lightemitting diode LED array of the CGI system in this study First a 64×64 chromatic LED array is independently developed to provide structural lighting for the CGI system Then the chips on the LED array are arranged according to a designed basket-weave arrangement Finally considering the physical structure of the chromatic LED array an interpolation algorithm is proposed for sampled images Experiment results show that the root mean square error RMSE of the basket-weave sampling is reduced by 4 6% compared with Cartesian sampling and it has better performance in storing high-frequency information of chromatic images In addition compared with the bilinear and bicubic interpolation algorithms the average RMSE of the algorithm is reduced by 2 0% and 6 4% respectively.
