pylon_camera_node/image_raw rate is lower than camera framerate

[Nanmei]

I use acA720-540uc camera, I set camera framerate 380 in the yaml, I use ros launch pylon_camer_node , the camer framerate is 328HZ . but i found the toplic of pylon_camera_node/image_raw rate is 60HZ. I want toplic rate is same to camera framerate (328HZ). how can i chang the code? thanks,wait for you reply

Hello @Nanmei
Check as well what kind of triggering you are using. When using software trigger, the frame rate may be decreased by 50%. That is why, you should either use free-run (no explicit external triggering), or external hardware trigger. This topic was discussed in different other issues already and there were implementations for that.
Try as well setting the parameter enable_current_params_publisher for the node to false? It seems that the publishing of the parameter significantly slows down image publishing.
