基于激光视觉原理测量玻璃中气泡的尺寸
Measurement of glass bubble size based on laser vision principle
摘要
Abstract
In order to measure glass bubble size in real time , a dynamic system for measuring glass bubble was built in laboratory with a linear laser diode , a linear CCD and a movement control system based on the laser vision principle .The laser spot projected onto the glass surface was imaged on the photosensitive array of the camera through its zoom lens .Gray images of glass bubbles were grabbed by Sapera CamExpert software with the combination of the transverse scanning of the camera and the longitudinal scanning of the movement platform .The transverse and longitudinal precision of gray images was discussed in theory .The criterion for distinguishing the bubble images from distortion was confirmed and the matching relationship between the clock frequency of work pixels and the longitudinal velocity of the float glass was deduced .Bubble gray images were grabbed at the different longitudinal velocities .The transverse and longitudinal pixel number of glass bubbles was measured by the Sapera Architect .The transverse and longitudinal size of bubbles was acquired by theoretical calculation.Comparing with bubble size measured with a ruler , the relative error of the longitudinal size is 0.18 and of the transverse size is 0.05.The results show that in the case that camera work distance , focal length and pixel cell size are fixed, the transverse size of glass bubbles can be measured by this system in the range of permitted errors .关键词
