Real-time detection of cartridge quality based on X ray
-
摘要: 为了能实时而准确地检测药筒质量是否合格，通过无损检测的方法，首先获取药筒的X射线图片，然后对其采取一些预处理算法，以提高图像的信噪比，并对图片内部特征分别采取文中提出的局部平滑度的极小值算法和局部均值极小法，提取相应的特征参数，并将其与标准的特征参数比较，进而可以判断药筒质量是否合格。该算法具有快速、准确、高效的优点，在现场测试中取得了很好的实际应用效果。Abstract: In order to detect the quality of the cartridge precisely in real-time, it is needed to acquire the X ray photo of the cartridge by Non Destructive Testing(NDT) method, then some preprocess algorithms are used to enhance the signal to noise ratio (SNR) of the image. The local average minimum algorithm and the local smoothness minimum algorithm are proposed to extract the feature parameters of the cartridge, which are compared with the normal cartridge parameter, and an identification report about the cartridge quality will be given. The method is fast, precise and efficient.
