The invention discloses a volume measuring method and device used for an express delivery. The method comprises the following steps: obtaining a volume measuring instruction for the express delivery;according to the volume measuring instruction, photographing a depth image of the express delivery through a binocular depth camera of a terminal; and determining the volume of the express delivery onthe basis of the depth image. According to the technical scheme, the volume measuring method for the express delivery is simplified and the volume of the express delivery is obtained automatically through photographing of the binocular depth camera. The scheme replaces a manual measuring and manual calculating solution by delivery workers. Volume measuring accuracy is improved while manpower costs and time costs are saved, and the user experience of both senders and delivery workers is improved.
