Abstract

The invention discloses a volume measuring method and system of a cargo carrying box body. A holder used for connecting and supporting a depth camera is installed in the cargo carrying box body. The method comprises the following steps of through a motion sensor in the depth camera, acquiring a plurality of attitude information of the depth camera, and according to the plurality of attitude information, obtaining a rotation matrix for converting a current attitude of the depth camera to a preset standard attitude; and based on the rotation matrix, obtaining point cloud data of the depth camerain the current attitude and converting to corresponding standard point cloud data in the standard attitude, fusing the standard point cloud data corresponding to the point cloud data in the pluralityof attitudes, and calculating a volume of a carried cargo in the cargo carrying box body according to a spatial position of the fused standard point cloud data. The scheme of the invention is simple,a result is reliable, performance is stable, the volume of the carried cargo can be conveniently known and the volume of the carried cargo is managed in a digitization mode.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a method and system for measuring the volume of a cargo box. Background technique [0002] With the development of the logistics industry, the freight business has received more and more attention. How to digitally manage the loading rate of the container and the volume of the cargo is an inevitable requirement for the logistics industry to improve energy efficiency. The existing volume measurement method uses the image captured by the camera and the point cloud splicing algorithm to measure the volume of the goods. This solution is greatly affected by the environment and has a large amount of calculation, so the measurement efficiency is low. Contents of the invention [0003] The invention provides a method and system for measuring the volume of a cargo box, which can measure the volume of the loaded cargo. The scheme is simple to implement, the measurement result is accu...
