*2.1. Data Acquisition*

Longjing 43 Tea Garden in Juyuanchun, Yangzhou, has a large planting area, standard tea garden and relatively flat shed surface, which meet the experimental requirements. Therefore, the object of our study was Longjing 43 in famous and excellent green tea. In this research, we collected images of famous tea buds in Juyuanchun tea garden in Yangzhou. In order to improve the fitness of the model and the environment, we chose to face the tender buds at a total of 5 shooting angles of ±30◦ and ±60◦ with the tender buds, respectively, during the shooting, as shown in Figure 1.

**Figure 1.** Multi-view bud image. (**a**) front view, (**b**) rotate counterclockwise by 30 degrees, (**c**) rotate counterclockwise by 60 degrees, (**d**) turn it clockwise by 30 degrees, (**e**) turn it clockwise by 60 degrees.

Due to the strong seasonality of the picking of famous and excellent tea, the quality of the dataset was the best in a few days before Tomb-Sweeping Day. Therefore, the shooting time of this time was 2 April 2023, and considering the influence of light on the dataset, a total of 1049 images were taken from 9 to 11 a.m. and 3 to 5 p.m., respectively. The resolution of the photos was 3904 × 2928. Figure 2 shows the overall layout of the tea garden, and Figure 3 shows the images of the dataset taken.
