Abstract: For the complicated noise information around the bridge crack，the traditional filtering method can get the denoising effect in some aspects when dealing with such noises，but they often have their own big defects. Therefore，based on the traditional morphological filter，an algorithm based on multi-angle multi-structure element morphological filter was proposed. By combining mathematical morphology，a variety of structural elements were combined to avoid the single effect of single structural element on image processing，which could not only analyze the whole region of the image，but also retain the detail information of the image. The comparison analysis on the experimental data shows that the proposed filtering algorithm has achieved remarkable results.
