I need to take a measure (Euclidean distance) over a selected points on an image. In order to make this simpler I broke down all the process in steps:
- Taking/Loading a photo (with a known pattern in it)
- Recognizing the pattern to calibrate measure
- Selecting points "from" and "to" in order to measure the distance between them
For my first iteration I will:
- load a picture (half of number 1),
- select the pattern manually (a rough approximation of number 2), and
- select point to measure distances between them.
I'm just beginning with OpenCV; do I need it for my first iteration?
