如何使用python获取此图像的某些颜色(RGB)的像素坐标?
我正在尝试进行室内导航，并且我需要机器人可以自动导航的室内地图.我正在考虑使用每个位置(某些部分)具有不同颜色的图像，并且我想知道获取某些颜色的坐标的方法.这样我就可以使用该坐标将位置指定到某些颜色区域.我目前正在使用pycharm
I'm trying to make an indoor navigation and I need indoor map that robot can automatically navigate the way. I'm thinking of using image which have different colors for each place(certain section), and I want to know the way to get the coordinates of the certain colors. So that I can designate places to certain color area using that coordinates. I am currently using pycharm
如何获取粉红色，紫色和黄色每个部分的坐标? 颜色的RGB代码为粉红色(255,128,255)，黄色(255,255,0)，紫色(128,128，255).
How can I get the coordinates of each of the pink,purple, and yellow part? RGB code of the colors are pink(255,128,255), yellow(255,255,0), purple(128,128, 255).
您的问题的解决方案将包括两个主要部分:
The solution to your problem will involve two main parts:
- 从输入图像中检测颜色
- 将blob转换为单个坐标.
让我们来解决第一个问题.您可以将cv2.inRange()用于各种颜色，以获取输入图像中每个标记正方形的二进制掩码.
Let's take the first problem. You can use cv2.inRange() with various colors, to get a binary mask for each of your marked squares in the input image.
现在，您可以在二进制蒙版上使用cv2.findContours来检测最大轮廓，并获取其中点或其他内容.
Now you can use cv2.findContours on the binary mask(s) to detect the largest contour and the take it's mid-point or something.
