I am using Logitech C270 with resolution 640x480 to detect aruco marker using aruco_ros package. I have succeeded to detect the marker when the distance between the marker and the camera is 180 cm. But I want to detect the marker when the distance between the marker and the camera is 240 cm. The marker which i used it from the dictionary 6x6. I tried with marker 5x5 but i failed. I think that when I can change the default dictionary from 6x6 to 4x4 I can solve this problem. I need help in changing the dictionary or any other idea assist me, Please.

if your marker is undetectable in image you can resize your marker(you can change the size of marker with parameter and print bigger or smaller marker) or use multi scale marker i think for using multi scale marker you should run 2 or more node or you can use one node and scale the out put.

Thanks for your answer hamid. But I cannot print marker with bigger size because I have limit on size.
