So I decided to give the Pix4D app a try. I took it to a school building that was in a pretty wide open area. I wanted to see how it worked before a tried to do my house which has a lot of trees around . The flight was almost like running a ground station flight. I used a Nexus 7, which I connected to a hotspot to download the imagery for the area I was in while on site. All that needs to be done is place a box on the area you want the quad to grid (it is adjustable) hit "start mission, next and hold start" for 3 seconds. One significant difference from ground station is when the quad takes off it goes straight up until it gets to altitude then flies to the starting point then starts the grid pattern. You do not have to touch the remote at all. You can watch the progress of the quad along the grid in the app in realtime. One thing that I did not expect was that the quad stayed in motion while taking pictures. With the amount of time the shutter takes I thought that was odd. The only pauses were at turns. I did a grid of 100x100. The app took 56 photos and created a file with all the geotag data. Looking back I should have widened the grid area to get a better side view.
Overall it was a pretty simple process. Pix4Dmapper needs a pretty beefy computer to run. If anyone would like to give it a try but does not have a computer beefy enough to process the data let me know, if I have the time I can process it for you.
Here was w quick first run of a school building.
