Parcel volume measuring method and system, storage medium and mobile terminal

Abstract

The invention provides a parcel volume measuring method and system, a storage medium and a mobile terminal. The method comprises the following steps that S100, a target image is obtained through a camera of the mobile terminal, wherein the target image comprises a plane marker, an upper surface of a to-be-measured parcel with the plane marker, and two side surfaces of the to-be-measured parcel adjacent to the upper surface; S200, image processing is conducted on the target image, so that the plane marker is recognized in the target image; S300, image edge detection is carried out on the targetimage, so that the angle points of the to-be-measured parcel are identified in the target image; S400, the world coordinates of the angular points are calculated based on the plane marker, the pre-obtained internal reference matrix and the angle points of the camera, so that the volume of the to-be-measured parcel is obtained according to the world coordinates of the angular points. According tothe invention, the volume of the parcel to be measured is accurately measured by using the camera built in the mobile terminal in a real-time manner; the use scene is enriched, additional hardware facilities do not need to be added, and the cost is saved.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to a package volume measurement method, system, storage medium and mobile terminal. Background technique [0002] Today, with the rapid development of the express delivery industry, there are a large number of express packages to be tested that need to be delivered by post. The billing method for express delivery of the package to be tested includes the method of weight or volume, and the courier will charge the maximum value of the two. Furthermore, the volume and size of the package to be tested will be entered into the system following the tracking number information of the package to be tested, so as to facilitate subsequent loading and inventory arrangements. Therefore, quickly calculating the volume of the express package to be tested has become a necessary technology. [0003] The invention patent with application number CN20151088222.6 discloses a volume measurement method a...

AI Technical Summary

Problems solved by technology

[0004] This method has the following disadvantages: a. An additional depth camera needs to be installed. The price of the depth camera is relatively expensive, and the cost of the express terminal device (or mobile phone) is relatively low. If all the depth cameras are configured, the cost is relatively high

c. At present, most depth cameras use structured light or TOF solutions. Structured light is easily interfered by strong light and cannot work outdoors.

The accuracy of the TOF depth camera is relatively low, and the error is greater under the interference of strong outdoor light.
