What's your exposure? And is the framerate higher for other formats?
When the exposure decrease, the framerate will increase, it can up to about 44fps while exposure is 6000 microseconds, but when I set exposure_auto to true, the framerate back to 30fps. And framerate is lower for other formats, such as rgb8 format, about 17fps. Using pylon viewer software is normal.
What's your exposure when you activate exposure_auto? @marceldebout
Hello. I’m experiencing the same issue. acA2040-35gc, Bayer 2048x1536, Ethernet, ROS Kinetic.
Do you have any ideas what could cause this?
I am also having the same issue with daA1600-60uc 1600x1200, USB interface, ROS melodic. Pylon Viewer ~41fps ROS Node ~ 20fps Is there already a solution?
same issue with acA2500-60uc. in ROS will not go above 18.84 Hz
I might be wrong but I believe that the reason for the difference in FPS is different grabbing strategies. Pylon viewer uses so-called “free-running” mode, which yields maximum FPS. This driver uses (presumably) WaitForFrameTriggerReady() + ExecuteSoftwareTrigger(), which is slower, but necessary for stereo/multiple cameras synchronization (I guess). If someone is not afraid to get his hands a bit dirty I could share my driver for GigE cameras (should work for other types with minor modifications), it is fast :-)
May be related to https://github.com/basler/pylon-ros-camera/issues/28 and/or https://github.com/basler/pylon-ros-camera/issues/29, even thought the implementation may be different in some part.
Hello, The camera I used is basler daA1600-60uc, USB interface, ROS is kinetic, when I use pylon viewer software to capture image with Bayer8 format, the frame rate can up to 60fps, but when I use this ROS package with bayer_rggb8 format , the output include this
the image can capture normally, but the image topic only 25.4fps. How to increase the frame rate? Thanks
