A method, device and equipment for measuring volume parameters of an object

Abstract

The invention discloses a method, a device and equipment for measuring object size parameters, belonging to the technical field of measurement. The method comprises the steps of: acquiring point cloudinformation of a target object; determining a shape of the target object according to the point cloud information of the target object; measuring to obtain length information, width information and height information of the target object by combining with background ground information when the shape of the target object is a regular cube; and performing a projection operation on the point cloud information of the target object to obtain the length information and the width information when the target object is in the shape of an irregular cube, and performing double integral calculation on the point cloud information of the target object to obtain the height information. The method, the device and the equipment can conveniently, quickly, automatically and precisely measure the size parameters of regular cubic objects and irregular cubic objects.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a method, device and equipment for measuring volume parameters of an object. Background technique [0002] In recent years, with the rise of the logistics industry, how to save logistics costs and improve the utilization of storage space has become the focus of people's attention. This invention is proposed to meet many pain points in the logistics industry. [0003] The traditional volume measurement of an object involves the relevant personnel manually measuring the length, width and height of the object, or placing the object in a large immovable device for measurement. The traditional object measurement method has the following defects: 1. The traditional measurement method has high requirements on the measurement equipment, and most of them rely on fixed volume measurement equipment, which cannot be moved; 2. The traditional measurement method is only suitable for a sin...

Problems solved by technology

The traditional object measurement method has the following defects: 1. The traditional measurement method has high requirements on the measurement equipment, and most of them rely on fixed volume measurement equipment, which cannot be moved; 2. The traditional measurement method is only suitable for a single measurement requirement (package shape in logistics). variety, not just a single cube shape), it is difficult to measure regular objects and irregular objects at the same time; The nature of the measured object presents requirements that do not apply to extended

[0004] In addition, the volume measurement method based on the depth camera in the prior art usually needs to use a noise reduction background plate for complex backgrounds to eliminate the noise interference of the background environment, that is, there are certain requirements for the shooting background, and there are also restrictions on the shooting angle. The measurement can only be carried out if the shooting angle can fully illuminate the three sides of the target object, and the volume measurement method based on the depth camera in the prior art is only suitable for the measurement of cube-wrapped objects, and cannot be measured for irregular objects

[0005] To sum up, the existing technology has shortcomings such as the need for a fixed camera angle of view, requirements for the orientation of objects, cumbersome measurement process, and low measurement accuracy when performing measurements.
