Cold region rice leaf age judgment method and device, computer and storage medium

The invention discloses a cold region rice leaf age judgment method and device, a computer and a storage medium, and relates to the field of leaf age judgment. The problems that a leaf vein deviation method is adopted in existing rice leaf age identification, certain manual measurement is needed, and deviation is large are solved. The method comprises the following steps: acquiring picture data and expert experience data; preprocessing the obtained rice picture data to obtain rice image data; training a neural network by using the rice image data to obtain an image recognition neural network; constructing a leaf age recognition model according to the picture recognition neural network and the expert experience neural network; and judging the rice leaf age according to the constructed leaf age identification model. The expert experience data comprises the maximum leaf number of the variety, the sowing date, the rice transplanting date and the accumulated temperature. According to the method, automatic identifi
