| Abstract: | Object recognition in very high-resolution remote sensing images is a basic problem in the field of aerial and
satellite image analysis. With the development of sensor technology and aerospace remote sensing technology, thequality and quantity of remote sensing images are improved. Traditional recognition methods have a certainlimitation in describing higher-level features, but object recognition method based on convolutional neural network(CNN) can not only deal with large scale images, but also train features automatically with high efficiency. It ismainly used on object recognition for remote sensing images. In this paper, an AlexNet CNN model is trained using2 100 remote sensing images, and correction rate can reach 97.6% after 2 000 iterations. Then based on trainedmodel, a parallel design of CNN for remote sensing images object recognition based on data-driven array processor(DDAP) is proposed. The consuming cycles are counted. Simultaneously, the proposed architecture is realized onXilinx V6 development board, and synthesized based on SMIC 130 nm complementary metal oxid semiconductor(CMOS) technology. The experimental results show that the proposed architecture has a certain degree ofparallelism to achieve the purpose of accelerating calculations. |
