Publish clicked point with orientation #741

Closed tky1026 closed 3 years ago

tky1026 commented 3 years ago

I would like to publish GPS coordinate message by clicking on the display, where point_click_publisher with frame set to /wgs84 get the job done perfectly.

However, I am looking to add orientation like how the move_base 2D Estimated Pose option works, such that the message field contains GPS coordinate + orientation.

point_click_publisher publishes PointStamped only; move_base Estimated Pose publishes pose message to /initialpose with data under map frame only and not changeable.

How can I achieve this?

There is not an existing way to do this using just mapviz.

One way we have done something like this is by creating a node which listens to two PointStamped and uses the relative heading between the two to create a Pose. The alternative is creating a new mapviz plugin based on point_click_publisher (or adding an option to it) which does something similar internally.

I'm thinking about how we could integrate this more easily into the UI. What if we did something like a click and drag, where you click where the waypoint should be, and then drag to the direction you want? After you release, the point would be published.

@tky1026, check out https://github.com/swri-robotics/mapviz/pull/716 and see if it does what you need. I based it off of the move_base plugin.

@knickels , this is exactly what I am looking for! Thank you!
