Which DetectorParameters can I set to improve detection of stamped ArUco markers?

Hi, I can only detect 11 symbols with default setting. I have tried out brute forcing by changing all DetectorParameters combinations and executing them over night but I could not improve the detection. Max detection is still 11.
Can you guys help me and tell which specific parameter I should change. The dictionary I am using here is new Dictionary(1, 3).

the picture looks overexposed. you should change how you take the picture.

Sry, I did not get what you mean by overexposed. But I have just attached the A4 size on which detechtion is done.
