将数学形态学中的高帽变换算法应用于液位高度的检测之中。利用形态学高帽变换, 并选用大结构元素, 对具有复杂背景的比色皿中的液位图像和分层液位图像进行处理, 实现了液位高度的快速准确检测。实验结果表明, 该方法适用于医学生化分析仪比色皿中样品液位高度的检测, 其原理也可以用于其他工业装置中的液位高度检测。

Top-hat transformation of mathematical morphology is applied to detection of liquid level height. Top-hat using morphology transformation, and choosing the major structural elements, the colorimetric melamine in cuvette images with complex background and hierarchical level image processing, can realize the detection of liquid level height rapidly and efficiently. The experimental results show that the method is suitable for the medical biochemical analyzer colorimetric analysis of sample liquid level height in the dish. The principle can also be used in other industrial devices in the level of detection.
