System for rapidly measuring density of irregular rigid object

Abstract

The invention discloses a system for rapidly measuring the density of an irregular rigid object. The system comprises six industrial cameras. The system comprises a material queuing mechanism, a material quality measuring device, a material surface image acquisition system and a material density measuring system based on image three-dimensional image reconstruction, the material quality measuringdevice is a platform scale capable of outputting measured data and is used for measuring the mass of a measured object. After measurement, a data line transmits the data to the computer. A method provided by the invention is one of non-contact measurement methods. Three-dimensional reconstruction is carried out by utilizing digital images obtained from multiple visual angles. The surface three-dimensional model of the measured object is obtained, the volume of the measured object is calculated, the density of the measured object is calculated by considering the mass data obtained from the platform scale, and compared with an existing method, a related device is simpler in structure, the complexity and time for measuring the density of the measured object are reduced, and the invention canbe conveniently embedded into an existing automatic production line.

Description

technical field [0001] The invention relates to the field of industrial technology, in particular to a rapid measurement system for the density of irregular rigid objects. Background technique [0002] Traditionally, two-step methods are used to measure the density of irregular rigid objects on the surface: 1) measure the mass of the object; 2) measure the volume of the object to be measured by the drainage volume method; [0003] This method is characterized by high measurement accuracy and mature technology, but there are follow-up problems such as the need to immerse the measured object in water, which may damage the measured object or require complicated cleaning. In addition, this method is difficult to achieve in the industrial production process. Fast and automatic measurement. With the development of technology, various density measurement methods are continuously proposed. These methods mainly focus on solving the second step in the traditional method, that is, volu...
