Real-time machine vision system for non-contact measurements of the masses of free-falling hot glass drops

The real time machine vision system for non-contact measurements of the masses of free falling hot glass drops is represented. The work of the system is based on preliminary optical processing of free falling hot glass drops images, videosignal input in the computer, analysis of the videostream in real time, selection of the geometric information, calculation of volume and mass of drop and statistical processing of results. The realized low cost system is used in the acting production of glass bottles. The error of measurement of masses of hot glass drops is 0,5-1%.
