不幸的是,颜色本身不会给你更多的信息比有机质和氧化物/氢氧化物。碳酸盐和硅酸盐的数量也可以检测到,但是没有进一步检查这些值会非常模糊的土壤。如果你想获得更多的信息需要更多的数据。晶粒大小例如(砂、粘土、淤泥)pH-measurements,水和空气的量,其他矿物质和盐度。你还需要关于土壤生物的信息,等等。收集所有这些数据需要进一步的研究方法。所以你的项目的想法是不错,但一幅单独不会带给你太多信息自土壤属性过于复杂。还编写这样一个程序(我想移动应用?)将是非常困难的,因为所有不同光线下的相机拍不同的照片. .而且他们都有一个不同的处理的图片。我不知道计算机视觉可以帮助因为你需要一个特殊的相机。 So if you want to make an app you're going to have a hard time. I don't think you want to design a special device just for this. Another aspect is that whenever you work with soil, you're going to get dirty. That's no good environment for such technology, that's why the munsell charts are used. It's no problem when they get dirty. I really like the idea, but I don't think it'll get you far, but that's just my opinion!
