A Method to Detect the Occurrence of Rice Plant Lodging Using Wavelet Transform

We propose a method to detect the occurrence of rice plant lodging in paddy field by image processing. Autonomous head-feeding combine needs to have ability to detect the occurrence of rice plant lodging during harvesting. Our method used USB camera image. USB camera is a cheap device and will be easy to be introduced. Wavelet transform was applied to define feature value. Our method could detect the occurrence of rice plant lodging even when light condition changes and when shadow exists in the image.
