@Spartan_007 did you ever figure this out? I'm wondering if you need to use PointCloud2ConstPtr instead for your callbac

rostest include ros node as dependency How do you include a ros node in your ROS_WS/src directory into your rostest unit

I have a stereo camera that gives me an X,Y,Z point for each pixel in the image. I detect an object in the image using an algorithm and get a bounding box. I then have a radar that also gives me detected targets with x,y,z track points. It would be very inefficient to merge (using ros_pcl) each and every xyz point from the stereo camera with the radar track points.

If the stereo camera and radar were co-located, I'd just trust that xyz points from the camera line up with xyz points with the radar, but actually the camera is several feet above and behind the radar, and as a result I need some math performed to convert the detected object in the image's xyz point to the equivalent xyz point relative to the radar.

So is there a ROS node that can take a displacement vector, describing the offset between two sensors, and transform the xyz points of one sensor to the other?

This would allow me to confirm the position of the detected object in the image with the position the radar reports. For example, in the simplest case let's pretend the stereo camera is precisely 1 meter directly behind the radar. If the camera reports a detected object is 15 meters away directly in front, then this transform I'm looking for would report that the object is actually 14 meters away - so that the end result is relative to the radar instead of the camera. Now I can precisely confirm: Does the radar also measure the object is 14 meters away?

I think tf2 will allow me to offset the camera x,y,z points, but unfortunately the distances would still read "15 meters" per my example above. Is there a node that will not only offset but subtract the distance between the two sensors, to get 15 - 1 = 14 meters?

I lowered the image resolution (using image_proc) down to less than half the original on my laptop, which has a much bet

tf2 TF error: [, when looking up transform I am getting a blank error when using TF2 for a command that otherwise works

Thank you again, I hadn't heard of eigen, but you're also right about static placement too and I think where I was mista

I greatly appreciate your response, but my issue with tf2 is that it applies to the entire pointcloud, which as I mentio
