alicevision/CCTag
Detection of CCTag markers made up of concentric circles.
This project helps engineers, researchers, and computer vision specialists accurately detect and locate special circular fiducial markers in images or video, even under challenging conditions. You provide an image containing these concentric circle CCTag markers, and it outputs their precise positions. It's designed for professionals who need highly reliable object tracking or camera pose estimation.
402 stars.
Use this if you need to precisely track objects or calibrate cameras using robust circular fiducial markers in environments where lighting or viewing conditions are difficult.
Not ideal if you need to detect standard QR codes, barcodes, or AprilTags, or if your markers are printed on bent or non-planar surfaces.
