- 摘要:
- 为应对快速识别大气环境下早期镀层腐蚀形貌特征的实际需求,开发了便携式形貌特征识别装置。通过硬件描述语言设计,在现场可编程逻辑门阵列( FPGA )内分别引入了中值滤波方法,抑制腐蚀形貌图像中存在的干扰脉冲和点状噪声;引入了直方图均衡方法,增强图像对比度;引入了最大类间方差阈值法( OTSU ),对增强后的图像进行阈值分割,获取腐蚀图像的二值化特征。最终,较为完整地提取出腐蚀形貌特征。结果表明:所研究方法与人为标注的腐蚀区域相似度能够达到 0.8441 ,同时通过 FPGA 极大地缩短了算法运行时间,处理速度满足便携式形貌特征识别装置的实时性需求。
- Abstract:
- : In order to meet the practical needs of rapid identification of corrosion morphology of the early coating in atmospheric environment , a portable equipment was developed. Through the design of hardware description language , the median filtering method was introduced in the field programmable gate array ( FPGA ) to suppress the interference pulses and punctate noise presented in the corrosion morphology image ; the histogram equalization method was introduced to enhance image contrast ; the maximum interclass variance threshold method ( OTSU ) was introduced to segment the enhanced image and obtain the binarization features of the corrosion image. In the end , the corrosion morphology features were extracted more completely. The results shows that the similarity of the proposed method to the artificially marked corrosion area can reach 0.8441 , and the algorithm running time is greatly shortened by FPGA , and the processing speed meets the real-time requirements of portable morphological feature recognition device.
