摘　　要：当前,新型组合坝体的主要材料是混凝土,混凝土开裂不仅会降低材料特性,还会直接影响结构的使用情况。人工测量不仅不准确且工作量巨大,而计算机在裂缝图像处理能够做到准确迅速。计算机图像处理技术存在的问题主要有测量精度较低、参数选取不全面、参数提取精度不够高和所需要处理时间长等问题。针对此情况,提出了OTSU改进算法的图像处理技术来提高图像边缘检测效果和参数的精度,减少边缘像素的模糊情况,增加特征参数提取的准确性,减少运行时间,为计算机图像处理技术更好的应用到混凝土工程裂缝检测方面提供一种有效的手段。At present,the main material of the new combination dam body is concrete,and the cracking of concrete will not only reduce the material characteristics,but also directly affect the use of the structure.Manual measurement is not only inaccurate and labor-heavy,but the computer can be accurate and fast in crack image processing.The main problems in computer image processing technology are low measurement accuracy,incomplete parameter selection,insufficient parameter extraction accuracy and long processing time.In view of this situation,the image processing technology of OTSU improved algorithm is proposed to improve the accuracy of image edge detection effect and parameters,reduce the blur of edge pixels,increase the accuracy of feature parameter extraction,reduce running time,and provide an effective means for computer image processing technology to be applied to the detection of cracks in concrete engineering.
