Seeding cavity detection and reseed are the key technologies in the process of super rice precision seeding. LabVIEW image processing technology first convert the color images which collected in tray movement to gray image,then gray image is converted into a binary image,and morphology of binary image processing,finally extract the geometrical characteristic of the binary image,the results show that LabVIEW image processing technology can meet the requirements of precision seeding for seeding cavity detecti...
