Problems solved by technology

[0002] With the deepening of e-commerce into people's daily life, the logistics industry is developing rapidly. During the consignment or transportation process, it is necessary to measure the measured objects such as parcels, but now the number of parcels is increasing, and the measurement work is heavy, and the measurement work Most of them still use manual measurement, which not only has low accuracy, but also has slow measurement speed and low efficiency. This situation needs to be improved urgently.

Abstract

The invention relates to a 3D camera volume measuring method and system. The 3D camera volume measuring method includes the following steps: acquiring a depth map of a measured object, wherein the depth map includes the depth information of the measured object; according to the depth information, extracting the measured object from the depth map, and obtaining the pixel area of the measured object; according to the distance between a 3D camera and a measuring platform and the depth information, obtaining the height of the measured object; according to the invariance of the view field ratio ofthe 3D camera and the pixel area, acquiring the length and the width of the measured object; and according to the length, the width and the height of the measured object, obtaining the volume of the measured volume. The 3D camera volume measuring method has the advantages of being simple in measurement, being convenient to implement, having no demand for artificial measurement, and greatly improving accuracy and efficiency.

Description

technical field [0001] The invention belongs to the field of logistics, and in particular relates to a 3D camera volume measurement method and system. Background technique [0002] With the deepening of e-commerce into people's daily life, the logistics industry is developing rapidly. During the consignment or transportation process, it is necessary to measure the measured objects such as parcels, but now the number of parcels is increasing, and the measurement work is heavy, and the measurement work Most of them still use manual measurement, which not only has low precision, but also slow measurement speed and low efficiency. This situation needs to be improved urgently. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a method and system for measuring volume of a 3D camera. [0004] According to one aspect of the present invention, a method for measuring the volume of a 3D camera is prov...
