A non-contact real-time measurement of lamp dimension based on machine vision

Journal Article


Abstract


  • In order to realize the online measurement of lamp dimension, the bulb image dimension measurement based on vision

    (BIDMV) is proposed. The image of lamp is obtained by camera. After image processing, such as Otsu algorithm, median

    filter, ellipse fitting and envelope rectangle fitting, the dimension of lamp can be calculated. Based on this method,

    a non-contact real-time measurement system of the lamp’s dimension is developed. The precision of the proposed

    method is 0.07 mm, and it can satisfy the tolerance of the National Standard GB15766.1-2008. The experiment results

    show that the proposed method has a faster measuring speed and a higher precision compared with other measurement

    methods.
