Image retrieval method and device, terminal and computer readable storage medium

The invention provides an image retrieval method and device, a terminal and a computer readable storage medium, and the method comprises the steps: obtaining a to-be-retrieved heterogeneous face image and a preset database, the preset database comprises a plurality of real face images, and each real face image is associated with a corresponding three-dimensional face image; performing texture matching on each three-dimensional face image based on the to-be-retrieved heterogeneous face image to obtain at least one heterogeneous face generation image corresponding to the three-dimensional face image; based on the similarity between the at least one heterogeneous face generation image and the heterogeneous face image to be retrieved, determining the similarity between the three-dimensional face image and the heterogeneous face image to be retrieved; and based on the similarity corresponding to each three-dimensional face image, determining a retrieval result of the heterogeneous face image to be retrieved.
