How to efficiently detect and track this marker?
Given the following images, I want to detect the location of the marker.
- GOAL: find center of marker
- no scale or rotation required
- 240x240 video feed running at around ~60fps
- implementation should be as light-weight as possible
- accuracy is not too important
What combination of OpenCV functionality would you recommend?
What I tried so far: - Detect contours, find rectangles and match them based on corners, this is too heavy though
Best guess: take a look at how aruco markers find their position. Also, in this case, I guess harris corners and looking for fixed constellations can get you quite far.
You can also look at what is done in Whycon: A precise, efficient and low-cost localization system. Also, what hardware are you using?
We use SIFT for this, u going on imav 2016??
Yes it's for IMAV! I'm curious, how are you matching the keypoints?
