Pressure detection method and device

The invention relates to a pressure detection method and device, and belongs to the technical field of terminals. The method comprises the steps: sequentially collecting n fingerprint image frames through a fingerprint recognition sensor, wherein n is not less than two; recognizing sweat pores from each fingerprint image frame; respectively obtaining the features of the sweat pores in each fingerprint image frame; determining the change trend of the pressure applied to the fingerprint recognition sensor according to the change trend of the features of the sweat pores in the n fingerprint image frames. The method solves problems that terminal equipment is large in size, is not portable and is high in cost because only if terminal equipment is provided with a dedicated pressure induction module, can the related technologies achieve a pressure detection function. The method saves the pressure induction module group, facilitates the light and convenient design of the structure of the terminal equipment, and reduces the cost.
