Abstract
A method for liveness detection includes: acquiring a first depth map captured by a depth sensor and a first target image captured by an image sensor; performing quality detection on the first depth map to obtain a quality detection result of the first depth map; and determining a liveness detection result of a target object in the first target image based on the quality detection result of the first depth map. The present disclosure can improve the accuracy of liveness detection.
