Dynamic detection method for falling ears of maize harvester based on improved YOLO-V4

Abstract: Traditional maize ear harvesters mainly rely on manual identification of fallen maize ears, which cannot realize real-time detection of ear falling. The improved You Only Look Once-V4 (YOLO-V4) algorithm was combined with the channel pruning algorithm to detect the dropped ears of maize harvesters. K-means clustering algorithm was used to obtain a prior box matching the size of the dropped ears, which improves the Intersection Over Union (IOU). Compare the effect of different activation functions on the accura… Show more

“…The young citrus fruit targets in the images were labelled using Labelimg image annotation tool and the images and labelled data were stored in PASCAL VOC format. After completing the labelling, the dataset was divided into training, testing and validation sets in the ratio of 7:2:1 ( Gao et al., 2022 ).…”

“…CNN neural networks are widely used in precision agriculture and smart agriculture, such as automatic species identification [10], disease identification [11,12] and fruit ripeness analysis [13][14][15]. Most of the research on crop and weed localization is based on object detection networks, such as You Only Look Once (YOLO) [16][17][18][19] series models and Region-CNN (RCNN) series models [20][21][22]. Zou et al [23] combined images with and without weeds to generate new weed images, and trained a semantic segmentation network called UNet, obtaining an accuracy of 92.21%.…”

“…Zhou Liping et al proposed an improved Otsu algorithm based ear root feature region detection for pig thermal infrared images [10] , which cannot accurately detect the ear root region of pig heads under dynamic conditions. Liu Gang et al proposed a thermal infrared video detection method for pig ear root temperature based on improved YOLO v4 [11][12] , which removes skewed frames of pig posture while retaining upright frames, which can easily cause information loss. Zhao Haitao proposed a pig body temperature detection and key temperature measurement part recognition based on infrared thermal imaging technology.…”
