While moving making photos

General Discussion
1

With the pix4d I had the drone cruising at 1m/s and every 4-5m it took a shot, without stopping/slowing down. The 1m/s was good enough to get good focused non-blurry images.

With litchi however the drone stops at every image, makes a shot, and continues to the next waypoint.

Any way how to create a survey where the drone doesn’t stop every photo but keeps moving at the cruising speed while making images?

Sidenote - thanks for the community support here on the forums. Very helpful.

And thanks to the makers of litchi, after some initial struggles I now after just 24h playing with it prefer it already over competition! :heart:

There are two ways to capture a series of photos:

  1. Place a waypoint at the location where each photo is to be captured and add a “Take Photo” action at each waypoint.
  2. Set a time or distance interval at a waypoint which will cause a photo to be captured at that predefined interval as the drone travels to the next waypoint.

Method number 1 will cause the drone to stop at each waypoint. Method 2 will allow the drone to fly at a constant speed as the photos are captured.

In Litchi’s newly implemented mapping feature, a waypoint is placed at every photo capture location. Most mapping software that I have used provides the user a choice of using either method 1 or 2 (or even a combination of the two). Perhaps this feature is still in the works. I feel it is a necessity because having the drone stop at each waypoint greatly increases the total flight time of the mission.

This is not the case.
The take photo actions are only for the DJI Fly drones as they don’t support the programmation of intervals.

When you fly using Litchi (Pilot or older apps), we use distance intervals, and a waypoint is only placed at the photo location when you are in AGL mode and the terrain is not flat (elevation diff is >1m from last photo)

Thank you for explaining - I just tried it indeed it works as you explained.

So I have a choice now. So much thanks for the response :folded_hands:

While stopping at each point to take the photo does increase flight time considerably, as you say, it can still in many cases be the desirable behaviour for drones with electronic shutters, i.e. consumer models not intended for mapping and such.
It is an easy way of ensuring sharp images without rolling shutter anomalies. In fact, the Phantom 4 had this behaviour as a selectable option (hover and shoot).

yes there is a clear visible difference between stopping and continuing the flight even at low speed.

Despite having a Hasselblad, especially in poorer light conditions this becomes VERY noticeable
