Abstract:

The live plant fine roots image monitor analysis system based on linear CCD was exploited, which eliminated the area CCD doliform aberration of the image, and realized unbroken analyzing the form of fine roots. Combining circle fine roots scan with portrait depth displacement, the system realized fine roots panorama image scan inside the minirhizotron. By the computer fine roots image procession system based on the fractal theory, the collected image was analyzed. The fine roots key growth parameters and the dynamic growth traits can be automatically calculated out quantitatively by the system based on pixel level. The system can be used in the fields of nursery planting and the crop growing module research in agriculture and forestry.

Key words: Linear CCD, plant fine roots, image monitoring, distributing density of fine roots, dynamic traits
