I need to detect the welding point on a large metal pipe, so I'm thinking of putting a marker on it to locate it. A color differentiating sensor would then be used to detect this mark.
對(duì)于大型金屬管焊接位置的檢測(cè)，我考慮在焊接位置上涂標(biāo)記。然后用顏色識(shí)別傳感器來檢測(cè)這個(gè)標(biāo)記。

I see, but it seems that the marked position would be difficult to detect because of the influence of the uneven colors around the welded part, right?
那樣的話，焊接時(shí)在周圍產(chǎn)生的顏色不均會(huì)造成影響，沒法順利地檢測(cè)到吧？

Yes, you're right. Do you have a better way of doing this?
是啊。有什么好辦法嗎？

How about using laser displacement sensors on the inside and outside of the pipe and detecting any change in thickness to locate the welding point?
在管道內(nèi)側(cè)和外側(cè)安裝激光位移計(jì)，用來測(cè)量焊接部的厚度變化怎么樣？
