The invention provides a crop growth analysis method and device and application, and the method comprises the following steps: obtaining a to-be-processed image containing crops, and carrying out the image segmentation of the to-be-processed image, and obtaining a segmented binary image; performing contour analysis on the segmented binary image to obtain a first contour binary image only containing a to-be-measured crop area and a gap area, and calculating the canopy coverage of the to-be-measured crop through the first contour binary image; performing contour analysis on the segmented binary image to obtain a second contour binary image only containing complete blue color segment information of the calibration rod, and calculating a pixel scale of the calibration rod through the second contour binary image to obtain the plant height of the to-be-measured crop; and analyzing the growth condition of the to-be-measured crop according to the canopy coverage and the plant height of the to-be-measured crop.
