Embodiment Construction

[0037] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary, and are intended to explain the present application, and should not be construed as limiting the present application.

[0038] The volume measurement method, device and storage medium based on binocular vision according to the embodiments of the present application will be described below with reference to the accompanying drawings.

[0039] There are three main methods for measuring the volume of an object, one is the laser ranging method, the other is the binocular stereo vision method, and the third is the infrared scanning method.

[0040] Laser ranging mainly uses fan-shaped laser cross-sectional scanning technology to quickly scan the v...

Abstract

The present application proposes a volume measurement method, device and storage medium based on binocular vision, wherein the method includes: acquiring the first cargo image and the second cargo image captured by the binocular camera; 2. Cargo image, obtain the depth map of the goods; determine the depth information of the goods according to the positional relationship between the depth map of the goods and the binocular camera; determine the outsourcing of the top surface of the goods according to the normal vector of each point on the top surface of the goods in the depth map Based on the outer envelope contour, use the least squares method to fit the minimum border of the top surface of the cargo to determine the length and width of the cargo; determine the volume of the cargo based on the length, width and depth information of the cargo. Through this method, the length, width, and height of the goods can be accurately obtained, thereby improving the accuracy of volume measurement, reducing volume measurement errors, and solving the technical problems of large limitations and low measurement accuracy of object volume measurement methods in the prior art .

Description

technical field [0001] The present application relates to the technical field of intelligent non-contact measurement and control, in particular to a volume measurement method, device and storage medium based on binocular vision. Background technique [0002] The volume measurement of goods entering the warehouse is one of the main technical difficulties in realizing unmanned intelligent storage. [0003] At present, in traditional logistics and warehousing, there are generally three ways to obtain the volume information of goods, that is, to measure the volume of goods by using laser rangefinder, binocular stereo vision measurement or infrared scanning. [0004] However, there are certain defects in the existing volume measurement methods, which mainly measure standard boxes and the measurement scene is fixed, and are mostly suitable for volume measurement of small and medium-sized and opaque objects. large and low measurement accuracy. Contents of the invention [0005]...
