Design of Recognition System for Rice Planthopper over Digital Signal Processor

摘要

To design a rice planthopper recognition system based on digital signal processor and target recognition algorithm over wavelet transform. The hardware system included mobile device using single-chip microcomputer as the core of control, and algorithm processing platform using digital signal processor as the core. The software system consists of image segmentation based on single-threshold segmentation, and target extraction of rice planthopper is based on wavelet transform. It used video camera to shoot crop video. Then input video signal to the digital signal processor of the recognition system and extract pictures, and identify the image of rice planthoppers. This system can realize that people do not need to visit the farm estate and easy to grasp the overview of rice planthopper and to keep abreast of the internal field details of the pest and to develop appropriate treatment measures.
