how to increase the resolution of logitech c920 to detect aruco markers more stably
I am using logitech c920(about 12ft above ground) to detect an aruco marker using the aruco_ros library. The resolution is set to 640x480 but at this resolution the aruco marker is not being detected if anything slightly comes in front of the marker. I wanted to see if i increase the resolution to 720p the aruco marker detection becomes more stable.
I tried to change it in the (edit:usb_cam-stream)launch file but that did not help. It gives this error - "No jpeg data found in image. Error while decoding frame."
I tried to change the pixel format to yuyv from mjpeg but it was giving some other error. "VIDIOC_DQBUF error 19, No such device"
I also tried to change the resolution using v4l2-ctl but there wasn't an option to change it.
Anyone know of a different way to increase the resolution or know of a different aruco library that does more stable detection? Also is there a camera that does aruco detection better that is not too expensive? The goal is to detect the markers well about 10-15ft away and also not completely lose the marker when there is a small obstacle(eg: 3in diameter ball).
Thanks in advance
