Hi, It is straightforward to calculate the detection FPS in this [example](https://github.com/luxonis/depthai-core/blob/main/examples/MobileNet/rgb_mobilenet.cpp). But when the detection queue is being controlled by ros bridge like this [example](https://github.com/luxonis/depthai-ros/blob/noetic/depthai_examples/src/mobilenet_publisher.cpp), what will be the best way to calculate the FPS? I currently have another node subscribing to the detection topic and calculate the FPS based on that. But is that accurate at all? Thanks Lincoln

Best way to get detection FPS when using ros bridge

Hi, for the ROS topic frequency you can use rostopic hz /topic_name. To analyze frequency of data on the camera directly, you can use depthai_pipeline_graph
