   void centerGameObject(GameObject gameOBJToCenter, Camera cameraToCenterOBjectTo, float zOffset = 2.6f)
    {
        gameOBJToCenter.transform.position = cameraToCenterOBjectTo.ViewportToWorldPoint(new Vector3(0.5f, 0.5f, cameraToCenterOBjectTo.nearClipPlane + zOffset));
    }

Then you can call it with 

centerGameObject(gameOBJ, Camera.main);

The default zoffset(2.6f) should work but you can change it by supplying the third parameter.

centerGameObject(gameOBJ, Camera.main, 6f);

  • @Sopheak I am assuming you also want your object to not disappear. In that case see my answer here on that topic: http://stackoverflow.com/questions/36686984/how-to-keep-tracked-image-target-model-object-after-tracking-lost/36687578#36687578 – bpgeck Apr 26 '16 at 01:18
