waypoint pan speed question

[hedbonker]

I want to construct a waypoint mission the sends the drone to a location, starts the recording, hovers for 20 seconds for WP 1. For WP2 I want to repeat what WP1 did but with the drone aimed in a different direction from WP1. I set all of this up and it works fine with one exception. The pan motion from WP1 to WP2 is much too fast. Is there any way to control it? The speed option only appears to control the speed of travel between waypoints.

Thanks!

Maybe try adding another waypoint in the middle of the pan motion to include in the pan motion, or by combining two half pans together after, assuming the pan speed between two points cannot be slowed down.

You have direct control over the rotational speed using these three parameters:

1. Distance between waypoints
2. Cruising speed
3. Difference in headings at waypoints

For example, if the distance between two waypoints is 10 meters and the cruising speed is 5m/s, the time it will take to travel that distance will be 2 seconds. Then, if the difference in heading of those two waypoints is 90 degrees, the drone will rotate at 45 degrees per second. Merely adding an intermediate waypoint will not change that unless it alters the distance, speed, etc.

Hi @hedbonker

Try this smethod:

1) Replicate WP2 and obtain new waypoints, like WP3, WP4, WP5 etc almost at the same location as WP2. (But the new WP5 is now actually the WP2 of your own scenario above.)

2) Add 3 dummy POI located in a suitable location (on an arc shape) so that, the camera will make the pan motion gradually (slowly) at each of the WP2, WP3, WP4, WP5 etc.

3) To make your shooting even better, you can increase the number of WPs and POIs in between the starting point and the end point of your flight, suitable for your satisfaction.

Wish you success.

Thanks so much - This worked well!

 

[Droning on and on...]

The extra waypoints seem overly complicated.

As @DJ Wes says, just set the travel speed between the two stacked waypoints to take the time you want the pan to last.

 

[Droning on and on...]

As has been explained, a changed in yaw angle will be interpolated between two waypoints, and pan smoothly from start angle at WP1 to end angle at WP2. so what you need to do is define the desired pan rate in °/sec and pan angle, do the easy math to determine how long the pan will take, then calculate the speed between waypoints so it takes that amount of time to transition.

The site below does the math for you and gives good ballpark numbers for a cinematic pan. I've used it to get an idea of what sort of timing I should be thinking about. I just use the Inspire 3 in the setup for any drone shot, it's worked quite well for any drone. Hope this helps!
