[0027] Please refer to figure 2 , figure 2 It is a flow chart of a volume measurement method provided by a preferred embodiment of the present invention. The volume measurement method includes the following steps:
[0028] Step S101, acquiring a three-dimensional point cloud model of an object to be measured.
[0029] In this embodiment, the 3D point cloud model can be used to reconstruct an entity with complex curved surfaces. Optionally, when the acquisition unit 115 is an ordinary camera, the image data of the object to be measured can be obtained from the acquisition unit 115, so as to obtain a three-dimensional point cloud model according to the image data, optionally, such as image 3 As shown, step S101 may include the following sub-steps:
[0030] Sub-step S1011, processing the collected image data of the object to be measured to obtain an initial point cloud model.
[0031] In this embodiment, the depth information of the collected image data of the object to be ...

Abstract
The invention provides a volume measurement device and device and a user terminal, and relates to the technical field of measurement. The method comprises the steps: obtaining a three-dimensional point cloud model of a to-be-measured object; constructing a test space for accommodating the three-dimensional point cloud model, wherein the volume of the test space is known; dividing the test space into a plurality of preset measurement bodies equally; obtaining the total number of preset measurement bodies which are located between the preset measurement body which is located at an outer side of the test space and serves as a seed point and the preset measurement body which is located at the edge of the three-dimensional point cloud model; and obtaining the volume of the to-be-measured object according to the total number, the volume of the preset measurement bodies and the volume of the test space. The method improves the test precision while the to-be-measured object is not damaged, and also can achieve the measurement of the volume of a to-be-measured object with a complex curved surface. The method is high in application value.
Description
technical field [0001] The present invention relates to the technical field of measurement, in particular to a volume measurement method, device and user terminal. Background technique [0002] Whether it is volume, mass or density, it is an attribute label of an object. Volume, mass and density have become an important parameter for understanding objects. Since ancient times, there have been many methods to measure the volume, mass and density of objects. Take volume measurement as an example. In ancient times, Archimedes calculated the volume of the crown by using the volume of overflowing water. Today, the volume of objects is measured by size. However, these methods have their own shortcomings, and their application range is narrow. Using overflow water to calculate the volume is not suitable for the volume of some precious cultural relics and water-soluble substances. Using the size of the object to measure the volume of the object, the accuracy of the calculation i...
