[标题]:A study based on image processing for the bridge crack measurement
[作者]:Xiaofei Zhou;Xiaowei Liu;Guansheng Yin;
[文摘]:This paper gives a non-destructive and non-contact inspection way based on image processing whichis introduced to detect bridge cracks. System architecture is also introduced and key algorithms incrack image processing is studied. These key algorithms are: image gray scaling, imageenhancement, image strengthing, gap survey and so on. In the end such method is used to measureactual gap and the reliability of such method on bridge inspection has been verified with the results.
