  • Hi,

    what kind of defect? Is it a visible defect? So you could use image processing techniques to detect it? And is your bottle visible from all sides, or being rotated while being photgraphed?

    If you have the image(s) of an intact bottle, you could analyze its structure and compare that structure to the image(s) of the test (maybe defect) bottle (if its a visual defect).

    As a starting point you could eg. just subtract the derivatives of both images and analyze the results.

    Yes. It is visible defect using image processing technique. The image is in 2D only and without rotated it. Below is my sample image.

    Hi,

    do you have a picture of a bottle with a typical defect? So we could compare both pictures.

    Hi,

    just a bottle with a defect to compare with the intact bottle.

  • Hi Bella,

    It seems you could compare the two different images, you could refer the link below for more information.
