ros usb_cam select timeout的问题
问题同上, 当出现
[ERROR] [1577096025.464443267]: select timeout
[usb_cam-1] process has died [pid 8073, exit code 1, cmd /home/ape0/catkin_ws_rp/devel/lib/usb_cam/usb_cam_node __name:=usb_cam __log:=/home/ape0/.ros/log/ed6a76aa-256b-11ea-aec4-c400ad3e7ef2/usb_cam-1.log].
log file: /home/ape0/.ros/log/ed6a76aa-256b-11ea-aec4-c400ad3e7ef2/usb_cam-1*.log
问题可能原因
- resolution is too high ,尝试将长于宽同比例改的稍微小一点.(与此同时如果有通过calibration 得到的camera info, 要重新calibrate,务必要保持这两个长宽一致)
- frame rate is too high尝试将frame rate 降低一些
将长于宽更改时, 如果还试图使用apriltag_ros等,检查长宽更改是否会影响定位的数据,很有可能定位会出现偏差,要把相应camera_info都改掉
