Abstract: Orientational planting cannot only make maize leaf growing consistently, but also improve
the leaf photosynthetic capacity of per unit area and yield of maize. The "tip" direction was detected
and the angle of deflection was measured by using contour curvature analysis method of maize seed,
the ponent of HSV space was preprocessed by Otsu method, the automatic extracting maize
seeds embryo and orientation information have been realized through image color space conversion,
segmentation, preprocessing, and its contour characteristic analysis. A rectangular region ROI in the
image was defined and counts up pixels within the region, the region-specific positive and negative
ROI pixels pared by TM threshold and the embryo side towards was identified. The
Zheng-dan958, Jun-dan20 and Zhong-ke11, and repeat three times by using the above methods. The
results showed that the average accuracy of embryo inspection was more than 95%; the direction
average angle was °.
