| Abstract: | Regarding the difficulty of detecting and recognizing the color similarity between the green apple target and the leaves in natural environment,a green apple detection and recognition method based on YOLOv3 network is proposed.The YOLOv3 network is used to detect the green apple target area in image.The threshold segmentation under HSV and YUV color space components in the target area is performed,and the H,V and Y,U components with better extraction effect of the green apple target are selected.Morphological operations remove the small areas that are not connected to get the green apple target.In the images of single fruit,two fruits and multi-fruits,the experimental results show that the true average positive rate of green apple target extraction under H,V,Y,and U components is90.12%,and the false average positive rate is 5.74%.Meanwhile,the Y component green apple target recognition in the YUV color space is the best,and the true average positive rate is 93.93%. |
