However, since express packages can only be measured in a specific cabinet, on one hand, the size of the express packages cannot be measured for packages larger than the cabinet body, on the other hand, the express packages can only be measured for the cubic volume, and a great measurement deviation exists for packages with special-shaped structures.

Chinese patent publication No. CN207529484U discloses an intelligent postal subsidy receiving terminal, which includes a volume measuring device, wherein the volume measuring device includes a length grating, a width grating and a height grating; the length grating is arranged at the top of the box body structure along the transmission direction of the weighing belt; the two height gratings are oppositely arranged on two sides of the weighing belt and fixedly connected with the box body structure; the width grating is fixed on the tops of the two height gratings. When the object to be mailed passes through the workbench surface of the volume measuring device, the volume measuring device obtains the volume information of the object to be mailed, and the volume information is processed by the controller and then sent to the intelligent operation desk. However, this measurement method can only be used at a fixed belt transport position, and there are large measurement deviations for the profiled wrapping.
