大部分的电压致热型设备由于温升不明显,故障判断难度较大,并且红外图像受到背景复杂,尺寸多的影响,导致红外图像特征提取困难,另外,大多数现有的检测工作依靠人工判别,且存在判断分歧。目前,代替人工判别的研究中,许多只利用单一的特征来表征热图像中的故障特征。针对此类问题,笔者提出一种基于多特征融合的电压致热型设备故障提取方法。此方法将红外图像多故障目标检测算法和多特征融合算法相结合,建立动态决策准则。首先提取红外图像的三种典型特征,包括颜色、纹理和轮廓特征,继而通过融合算法(串行融合、并行融合和DCA ...

Research Of Small Weak Target Detection Under Complex Cloud Background [PDF]
复杂云天背景下的红外弱小目标的检测问题是红外成像系统中一个热点问题,探索和研究新的弱小目标检测理论和算法以及如何将现有的检测理论用于弱小目标情况是一个十分重要的课题,并且具有深远的意义。由于红外弱小目标图像信噪比低,目标的像素较少,缺乏结构信息,可供分割与检测算法利用的信息很少,所以对其研究一直是一个难点。 本文首先分析了红外弱小目标的一些相关概念和红外图像的数学描述,在此基础上围绕红外弱小目标检测问题对红外图像中的三个要素(目标、背景和噪声)进行了相应的分析。小目标在图像中的灰度可以不是最高的 ...

Target Detection Under Low Light Conditions Based on Visible and Infrared Images [PDF]
Image fusion is the process of combining multiple input images into a unified single image. Although visible-infrared image fusion enhances target detection accuracy, its performance often fails in low-light scenarios.

红外热像仪测温是电气设备状态检测的重要手段。在实际应用中,存在红外图像边缘粗糙模糊、噪声干扰严重等缺点,这给红外图像处理带来了极大的不便,为此提出一种基于改进Sobel算子和自适应最佳阈值的边缘提取算法。该算法利用八方向模板的Sobel算子对含有噪声的红外图像进行高温目标区域的边缘提取;通过广义高斯分布(GGD)描述图像的小波子带系数,并基于其间系数的局部领域信息进行方差估计,由此得到自适应最佳去噪阈值;结合改进Sobel算子和最佳阈值,最终得到所需边缘提取图像。MATLAB仿真结果表明 ...

随着红外测量技术的不断进步,对绝缘子状态进行红外热像检测逐步应用于电网的日常巡检中,但测量结果受环境因素影响显著。以输电线路现场运行中瓷绝缘子作为研究对象,分别在不同光照强度、湿度、温度与风速下采集绝缘子的红外图像,研究环境因素对绝缘子红外检测的影响规律。研究结果表明,当采用基于绝缘子串温度曲线的判别方法时,光照强度容易引起零值绝缘子的误判,温度变化对零值绝缘子检测没有影响;湿度变化会影响绝缘子钢帽的温升;在强风条件下,各绝缘子钢帽温度相同,不适合进行绝缘子红外检测。研究成果可用于指导电网红外巡检工作 ...
