ArUco with OpenCV in unity to detect small size markers #34

Open Abdullahallwati opened 4 years ago

Abdullahallwati commented 4 years ago

I have a project that requires developing an AR application. Right now, I am trying to setup that AR environment in Unity to detect a marker that is 10mm x 10mm in real-life size. I have tried Vuforia, EasyAR and AR foundation to detect the marker, but it was not possible. However, if I changed the size to be 20 x 20 mm then they will start detecting it easily, but I am required to use 10x10 mm. I was wondering if I can use OpenCV and ArUco with Unity to detect markers of this size.

The best answer would be to try directly. The minimum marker size you can detect with any AR library depend on two parameters: your camera's resolution and the distance between the camera and a marker. Because the marker must have a significant size on the camera's image. Therefore, a higher camera's resolution allows smaller detected marker. Likewise your camera must be close enough from a marker to detect it.

At the moment, AruoUnity is only working on Windows and Linux. Android and iOS are not supported yet.
