中文摘要:
      在振动噪声信号处理中,对于复杂曲线图像包含的数据,传统的提取方法效率低、难度大,影响后续的数据分析。为解决这一问题,本文融合曲线连续性、复杂曲线之间的空间特征以及RGB模型的特点,提出了一种针对两条曲线的识别提取算法和一种针对多条彩色曲线的识别提取算法,通过分别识别、提取、存储各曲线的坐标数据,对各曲线进行插值,仿真实现了复杂曲线图像的数据提取。本文提出的算法能够快速得到精确的曲线图像处理结果,为进一步分析、处理振动噪声信号图像中的复杂曲线数据提供了参考。
英文摘要:
      In signal processing of vibration and noise, It is inefficient and difficult to extract data from the image containing complex curves in traditional method, and affects data analysis. In order to solve this problem, The paper combines the continuity of curve, the spatial characteristic between complex curves and the characteristic of RGB model, An algorithm aimed at identification and extraction of two curves and an algorithm aimed at identification and extraction of color multi curve were proposed, through recognizing, extracting, storing the coordinate data of each curve, and interpolating each curve, the simulation achieved data extraction of complex curve image. The proposed algorithms can quickly obtain the accurate result of curve image processing, and provided a reference for analysing and processing complex curve data of the image.
