| Research Abstract |
A real time sensing technique for detecting lodging posture of crops was investigated using a laser scanner. In the laboratory experiment, posture profiles of a wheat bunch with four lodging directions (left, right, front, back) and three lodging angles (40°, 62°, 80°) were measured, and the profiles were assessed through comparisons with digital images. Also, inclination, skewness, and kurtosis were calculated using coordinate data of lodging profiles in three dimensions and the effectiveness of those values as indications representing lodging characteristics was assessed.
