[0048] In actual use, the shade cover is kept at a certain distance from the plant. Due to the varying direction and brightness of sunlight throughout the day, sunlight shines on the plant through the gap between the shade cover and the plant. The sunlight is extremely strong, far exceeding the brightness of the light source inside the shade cover. Therefore, when sunlight shines on the plant, the images captured by the recognition sensor are all overexposed, making it impossible to distinguish between crops and weeds. A blocking component is installed on the edge of the shade cover near the ground. This blocking component, resembling an extended skirt structure (not shown in the figure), extends circumferentially along the shade cover. This skirt structure effectively blocks the gap between the shade cover and the plant, completely blocking excess sunlight and creating a completely dark environment below the operating mechanism. The brightness within the recognition range comes entirely from the supplemental lighting.
