Volume measuring device, scanning inspection equipment and volume measuring method

Abstract

The invention relates to a volume measuring device, scanning inspection equipment and a volume measuring method, wherein the volume measuring device comprises the components of a first measuring device which is used for measuring the area of each cross sections, which are successively cut in a first direction every preset time interval and are perpendicular with the first direction, of a measuredobject, wherein the first direction is a relative displacement direction between a first measuring device and the measured object; a second measuring device which is used for measuring a relative displacement between the measured object and the first measuring device in each preset time period; and a volume calculating device which is used for performing accumulation summation of a product betweeneach cross section area and the displacement in the corresponding preset time period according to the measuring results of the first measuring device and the second measuring device, thereby obtaining the volume of the measured object. The volume measuring device can measure the measured object in moving and realizes no restriction to the shape of the measured object and relatively wide application range. Artificial participation is reduced in a measurement process, thereby preventing measuring precision reduction caused by man factors and realizing higher accuracy and higher reliability of the measurement result.

Description

technical field [0001] The invention relates to the technical field of volume measurement, in particular to a volume measurement device, scanning inspection equipment and a volume measurement method. Background technique [0002] At present, in many occasions, it is necessary to quickly and accurately measure the volume of fixed or moving objects with regular or irregular shapes, such as yard timber, bulk cargo and containers. There are three main methods of volume measurement: [0003] 1. Manual measurement based on the ranging sensor, manually using the ranging sensor to measure the three-dimensional coordinates of multiple feature points of the measured object, and measure the volume through three-dimensional modeling; [0004] 2. Based on image sensor measurement, this method uses several multi-directional visual sensors to obtain images taken by the measured object, and perform three-dimensional modeling to calculate the volume; [0005] 3. Based on the three-dimensio...

AI Technical Summary

Problems solved by technology

[0007] 1. The measurement cycle of manual measurement is longer, and the measurement accuracy is greatly affected by human factors;

[0008] 2. It is difficult to install multiple image sensors. After the device is moved, it needs a complicated camera calibration work, and it is greatly affected by weather changes and light. The shadows generated by external objects will also affect its image acquisition and processing. Affected, resulting in large measurement errors, and the system as a whole is not easy to move;

[0009] 3. Three-dimensional laser scanner measurement, its work efficiency is low, the equipment is expensive, and the work of data processing in the later stage is more cumbersome
