Hello, I’m new to OpenMV.
What I want to do is get all rectangles in a color chart and then get their color.
Next is to compare my PH test paper to the chart. Find the most likely PH value.
I tried to find edges or template of the rectangles but it only work in GRAYSCALE.
But I cannot get the color.
So I want to ask how to convert RGB image to Gray or how to do match template for a RGB image.
Thanks a lot.
