Greetings: I am using a 3DR X8, Pixhawk with a NEX5 for standard mapping/photogrammetry. I want to map a cliff face. Is it possible to create an autonomous flight in Mission Planner that will photograph the face in a grid-style pattern up-down and left to right (or vice versa) with the same kind of image overlap that you can do on a vertical mapping project? Think photogrammetry turned sideways to map in a vertical plane as opposed to the normal horizontal plane.
I can use a gimbal set at 90 degrees and create the waypoints fairly parallel to the face but can't figure out the up/down part at a specific waypoint. I have seen this done with oblique images that are manipulated in specialized software (EG PIX4D) but not with images taken parallel to an object in an 'up-down' format.
All help gratefully appreciated and accepted.

Did you ever figure our a good procedure for vertical face mapping?
Thanks for posting
I haven't flown a copter for a while (mostly fly planes) and I do not have SITL handy but I suggest you try it out in SITL first. If you haven't set up SITL yet, check it out here, it will save you a lot of time when trying to figure things out.
Andreas, I'm not really familiar with that command (seems more for planes than copters); will take a look at it.
Thanks
I think what you might be looking for is the LOITER_TO_ALT type of waypoint in MP.
Hello Everyone.
I've been investigating for a (relatively) simple, reliable, and "all-round" planning tool or method to use for vertical structures, landslides, cliffs, power-lines, etc.
- Using Mission Planner (free): I implemented something similar to Felipe's approach, where you basically use an essentially manual "copy-paste" method to create/replicate parallel way-points (or lines of) at different altitudes - I've not flight tested though - @Felipe: have you field tested these kind of missions? And what do you think in terms of safety and results?
- Using Tower (free): the Structure Scanner feature can be used for buildings (or objects for which circle surveys are adequate); pretty straight forward to set-up and use.
- Using QGC (free): I have not looked into it, but I feel MP and Tower are better; please advise otherwise if you know.
- Using UgCS (non-free): I'm investigating if the ONE license ($65) has the more advanced planning tools that allow "vertical" mission planning; it would probably be the most user friendly, safe, and complete, at least that I know of.
It would be nice to have some sort of guide on this topic - I make myself available if anybody else wants to join resources/experiences.
Hi everyone,
Guys, I think I figured out the vertical wp problem...
At least, for my aplication it's enough...
In flight plan, I add all way points that I need, after, I copy the coordenates (lat-long) that I need for all of waypoints... after I set the altitude for each one. All of the points will be at the same position and what will be change in flight its just the altitude, where I can set the command that I want.
i am also interested in this question ... some news ?
I am also interested in this capability, to conduct repeated surveys of the condition of tall structures as a way to estimate future maintenance or repair projects.
