液体混合浓度场检测方法
摘要：
本发明涉及一种用于液体混合浓度场表征的方法。更具体地说，涉及一种利用脱色反应颜色变化的特点，来表征不同液体混合后整个混合区域浓度场的方法。无色的溶液作为水的携流剂A，蓝色的淀粉I2溶液作为农药的携流剂B，将带有携流剂A的水和带有携流剂B的农药同时注入到混药器中进行混合；随着混合过程的进行，混合液颜色会发生变化；混合器混合区域部分采用透明的材料，高速CCD相机通过透明的混合区域来获取农药和水混合后的图片，对获取的图片经过灰度二值化、水平集和边界跟踪等图像处理等技术处理后表征浓度场信息。本发明简单实用，成本低且机动性好。
摘要（英）：

The invention relates to a method for characterizing the mixture concentration field of liquids, in particular to a method for characterizing the concentration field of the entire mixture region by using the characteristics of decoloration color changes after different liquids are mixed. A colorless solution is used as a flow-entraining agent A of water, a blue starch I2 solution is used as a flow-entraining agent B of pesticide, the water with the flow-entraining agent A and the pesticide with the flow-entraining agent B are simultaneously injected into a mixer for mixing, and along with the mixing process, the color of mixed liquids can change. A part of the mixed region of the mixer adopts a translucent material, through the translucent mixed region, a high-speed CCD (Charge-Coupled Device) camera captures pictures after the water is mixed with the pesticide, and concentration field information is characterized after processing the captured pictures with image processing technologies, such as grey scale binary, level set, boundary tracking and the like. The invention has the advantages of simplicity, practicality, low cost and good maneuverability.
