The invention provides a tobacco leaf thickness measuring method and device, and the method comprises the steps: collecting an original image (a first image) of a to-be-measured tobacco leaf through a microscope, carrying out the three-dimensional correction, obtaining a second image, carrying out the calculation of the second image through a three-dimensional matching algorithm, obtaining an initial disparity map (a third image), smoothing and optimizing the image through WLS filtering, and obtaining the thickness of the to-be-measured tobacco leaf. The method comprises the following steps: carrying out initial disparity map processing on tobacco leaves to obtain an initial disparity map, processing noisy points and mismatching points in the initial disparity map to obtain a processed disparity map (a fourth image), carrying out depth map calculation on the obtained processed disparity map to obtain a fifth image, carrying out depth value calculation and microscopic magnification reduction through depth info
