How to change the frequency of the camera? #119

Closed helloworld202 closed 3 years ago

helloworld202 commented 3 years ago

System Description Camera Name and Model:Blackfly S BFS-U3-51S5C Operating System: Ubuntu16.04 Spinnaker Version: 2.0.0.147 ROS Version: kinetic

When I set the parameter fps=40, the frequency obtained in Spinview is 40 hz, but the frequency of topic /camera_array/cam0/image_raw is always around 17. I tried to expand the buffer on this topic, but it didn't work. Is there any good idea to solve this problem?

A common problem is when you are using the camera in a dark area, it automatically adjusts the exposure time to get good images. You can try setting the exposure to a low fixed value to see if it helps. Remember exposure values are in micro seconds.
