First,camra are with different ID.In the firmware of camera,the id of camera used for traffic_light is different from the camera used for obstacle. Then apollo use udev rules to rename video1 to obstacle.Those material could be found here
If you could not flash camera firmware,you could just make a soft-link.

UBSYSTEM=="video4linux", DEVNAME=="/dev/video0",ID_SERIAL=="Leopard_Imaging_AR023Z_1_0000001001", MODE="777", SYMLINK="/dev/obstacle"
I add this rule in 100-leopaed.rules in /etc/udev/rules.d/.., however neither MODE is changed nor SYMLINK is created, reboot or replugin all doesn't work. I do not know why this configuration file do not work, I am working on ubuntu16. Is there anything wrong with this rule??? @gengqx

Do you mean the ID_SERIAL you can get from this command"udevadm info --query=all --name=/dev/video0" @gengqx
