| Abstract_FL | At present,target detection technology is gradually applied in agriculture,but there are still problems in the application of farmland pest detection,such as slow detection speed and low detection accuracy,and only predicting the type and location information of pests is not enough to meet the complex engineering needs.In this paper,a high speed and high precision farmland pest detection model MRA-YOLOX(masked autoencoders and rapid aim detection-exceeding YOLO),which can be used to predict additional pest status information,is proposed by fusing MAE and YOLOX algo-rithm.By constructing nearly 40 000 pictures and more than 50 000 labels dataset TDBFP(target detection dataset be used for farmland pests),the TDBFP dataset labels the growth status,species category and location of 10 kinds of pests,so as to better grasp the information of pests and develop more accurate countermeasures.Firstly,the decoupling head and loss of YOLOX model are modified to output additional growth states to improve model prediction.Secondly,ECA and SA attention mechanisms are organically integrated,and the connection process between backbone and FPN and the channel stacking process of FPN are inserted,so as to enhance the ability to obtain global information and enrich context information and achieve better results than a single attention mechanism.Finally,the self-supervised decoder part of MAE is inserted into the data enhancement part of YOLOX in order to expand the receptive field,enhance the recognition granularity,and obtain the data enhancement effect beyond mixup and mosaic.Experimental results show that when it is necessary to perceive the state,classification and position of the target at the same time,compared with the original YOLOX model,the detection accuracy of MLA-YOLOX for TDBFP dataset mAP@0.5 increases from 60.1％to 88.2％,the average detection accuracy increases by 18.8 percentage points,and the detection frame rate reaches 145 FPS,MLA-YOLOX can be used for more complex engineering. |
