基于图像识别的无人机精准喷雾控制系统的研究
Design of a precision spraying control system with unmanned aerial vehicle based on image recognition
摘要
Abstract
Objective]In order to improve the efficiency and utilization of conventional unmanned aerial vehicle ( UAV) spraying in fertilizer and pesticide applications, an variable rate UAV spraying system was developed based on image recognition.[Method]Median filter was applied to the images for denois-ing.K_means clustering algorithm was then used to segment the UAV images to extract 22 texture features and the color of non-crop region.Support vector machine ( SVM) classifier was designed for classification.According to the 17 selected characteristic parameters, the non-crop region was recognized through the SVM classifier with Radial basis function ( RBF) as the kernel function.Finally, precision spraying was achieved with controllable nozzles based on the recognition results.[Result]The recognition accuracy reached up to 76.56%.In undisturbed wind farm, the reduction rate reached 32.7%with the threshold P of 10%.[Conclusion]This research can serve as reference guides for application of precise spraying control technology in agricultural aviation.关键词
