Abstract

The invention provides a volume measurement method for an object on a conveyor belt. The method is capable of quickly and automatically determining the volume of the object on the conveyor belt. The method comprises the steps of collecting an image without light stripes and an image with light stripes by means of a monocular camera; according to the image without light stripes and the image with light stripes, determining the internal parameter matrix of the camera and a pixel coordinates set for the center of the light strips; based on the pixel coordinates set for the center of the light strips, determining a light plane equation; according to the internal parameter matrix of the camera and the determined light plane equation, determining the three-dimensional coordinates of a surface point of the conveyor belt and the three-dimensional coordinates of a surface point of the object; according to the determined three-dimensional coordinates of the surface point of the conveyor belt and the determined three-dimensional coordinates of the surface point of the object, determining the volume of the object. The method is applicable to the technical field of measuring.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a method for measuring the volume of objects on a conveyor belt. Background technique [0002] Belt conveyor (also called: conveyor belt) is a continuous transportation machine widely used in coal, construction, metallurgy, electric power and other industries. In order to count the total amount of incoming raw materials and output products, and obtain results quickly and accurately, measuring the volume of objects conveyed by the conveyor belt has become one of the solutions. Most of the traditional measurement methods are based on manual and offline methods. The labor intensity of workers is high, the efficiency is low, and the real-time performance is poor, so the production line cannot be monitored in a timely and effective manner. In order to adapt to the production of modern industry, it is necessary to study efficient, automatic and real-time measurement technology and...
