ArUco markers are 2D bar code similar to QR-code consisting of single or several segments. Single marker contains a whole number in the range 0 through 999999999999. You can find detailed information regarding ArUco markers at docs.opencv.org.
Using ArUco marker detector, TRASSIR can:
- detect ArUco markers both on static and moving objects;
- decode marker content and display it on operator's display;
- use marker content in the scripts.
Recommendations on the camera selection and its configuration:
- Camera of any resolution can be used to work with detector however the size of single marker segment in the frame should exceed 25x25 px.
- The bitrate on the camera should be adjusted to provide transmission of video signal without artifacts.
- Marker image on video in detection zone should be distinct and contrast.
Recommendations on the camera selection, its location and shooting area lighting:
- Shooting area where markers detection takes place should be well lit. Shadows and highlights presence on the marker will reduce probability of its detection and decoding.
- The camera should be mounted in such a way to provide full view of the marker. Partially covered marker will not be detected by the detector.
- The marker should be located at the flat surface. It is allowed to position the marker at the angle not exceeding 45 degrees to the shooting area. Inclination angle increase will reduce probability of its detection and decoding.
