Hello everyone,

I am working on a project and have a requirement to record image processing timestamp.

Reference:

http://docs.ros.org/jade/api/video_st...

The following returns only the publishing time:

pub.publish(*msg, cam_info_msg, ros::Time::now());

How can I get the time when it receives image (before processing)?

Best, ARM

Hi, you can call ros::Time::now() to capture clock right after you receive image,

ros::Time begin = ros::Time::now();

you can have more detailed look at Ros Time here
