[0054] like figure 1 As shown, the device of the method for correcting chlorophyll fluorescence parameters includes an imaging system consisting of a CCD monochrome camera 1 , a 10 mm lens, and a filter wheel 14 . Six working positions on the filter wheel, including 680 nm bandpass filter, narrow band 440nm, 520 nm, 690 nm and 740 nm filters, and zero position (no filter). 680nm bandpass filter, filter for dynamic fluorescence measurement, narrowband 440 nm, 520 nm, 690 nm and 740 nm filter for multispectral fluorescence measurement, zero (no filter installed) for red Light reflectance image acquisition. Plants 2 of different genotypes are planted in the tray 3 in the same manner, and the tray is placed on the conveyor belt 4, so that plants in different trays can all enter the field of view of the camera. In order to obtain dynamic fluorescence, steady-state fluorescence and red light reflectance images, the system provides 4 actinic light sources (620 nm) and 4 ultraviolet...
