The invention provides a wheat stripe rust dynamic monitoring method and device. The method comprises the following steps: acquiring hyperspectral image data of a wheat planting area; acquiring spectral reflectivity of a first preset wavelength and a second preset wavelength according to the hyperspectral image data; calculating a stripe rust sensitivity index according to the spectral reflectivity of the first preset wavelength and the spectral reflectivity of the second preset wavelength; and obtaining the wheat stripe rust disease severity according to the stripe rust sensitivity index. According to the wheat stripe rust dynamic monitoring method and device, the hyperspectral image data of the wheat planting area is obtained, the stripe rust sensitivity index is calculated according to the spectral reflectance of the first preset wavelength and the spectral reflectance of the second preset wavelength, and the wheat stripe rust disease severity is obtained according to the stripe rust sensitivity index.
