The cutting control of the cabbage (a) by the control device 40 is performed as follows. That is, the cabbage (a) is started to be harvested by the headed vegetable harvesting machine 1 (step 101), and whether the front vegetable sensor 32b detects the cabbage (a) (step 102) or if NO is detected, the process proceeds to step 102. Return. If YES is detected, the camera 36 is controlled to start by the control device 40 (step 1
03), it is detected whether an image photographed by the camera 36 is input (step 104), and if NO is detected, the process returns to step 104. If YES is detected, a density difference is detected from the grayscale image of the input image (see FIG. 5) (step 10
5) If NO is detected, the process returns to step 105. YE
When S is detected, the density difference is subtracted to detect a boundary line (see FIG. 5) (step 106), and when NO is detected, the process returns to step 106. If YES is detected, the number of pixels within the boundary line is detected (step 107), and if NO is detected, the process returns to step 107. When YES is detected, the number of detected pixels is compared with the preset number of pixels that have been set and stored, and it is detected whether the number of pixels is equal to or more than the predetermined number of pixels (step 108). When NO is detected, the cabbage (a) is a small cabbage (a). Is determined (step 109). If YES is detected, it is determined to be a large cabbage (a) (step 11).
0), the rear vegetable sensor 32a is a large cabbage (a)
Is detected (step 111), or if NO is detected, the process returns to step 111. When YES is detected, the left and right cylinders 30 and the cutting motor 31 are controlled by the control device 40 (step 112), the cutting blade 25 approaches the large cabbage (a) (step 113), and the large cabbage (a) is cut. Then, the left and right cylinders 30 and the cutting motor 31 are stopped and controlled by the controller 40 (step 114) (step 115). The above steps 102 to 115 are repeated, and large cabbage (a)
Is harvested.
