| Abstract: |
| To automatically dispose garbage according to its category, the automatic recognition of garbage can be realized by doing research on the vision based garbage detection and classification model. YOLOv5s network is taken as a garbage classification and detection model and trained on the self-made garbage data set. The trained YOLOv5s network extracts the features and location information from different kinds of garbage images, and then recognizes and detects different garbage in the image. The performance of the trained YOLOv5s is validated in a real situation. Garbage classification and detection model which was based on YOLOv5s can identify six different kinds of garbage effectively. The mAP of the trained YOLOv5s is 99.38%, the recognition accuracy is 95.34%, and the speed of target detection reaches 6.67FPS.The experiment results show that the garbage classification model based on YOLOv5s has high accuracy, good robustness and fast speed under different situations such as illumination, camera angle, etc. At the same time, this study can help enterprises to realize intelligent sorting and improve the efficiency. |
