"Im not sure but when doing an Auto mission and given the CAM_TRIGG_DIST parameter, these red boxes are supposed to show the footprint of the image taken."

Luke Wijnberg commented on Rory San Miguel's blog post AeroPoints: new smart ground control points for easy survey grade drone data
"Great idea and a fun thing to integrate into your workflow, but sadly will not work here in Africa. We loose on average 2 targets per sortie and those are just paper printed ones. Imagine how irresistible these fancy ones with solar panels will be…"

Luke Wijnberg replied to Paddy Dangerfield's discussion Hydrographic surveying
"Hi Paddy. Bodies of water do not do well with photogrammetry. There are no tie points on the surface of water for the model to photogrammetrically render itself. Try a test over a pool of water and you will find Mount Everest suddenly appears! In…"

Luke Wijnberg commented on Luke Wijnberg's blog post Emlid Reach for placing GCP
"Hi @kiki boy . You are quite right that Reach is capable of recording data up to those speeds. For a moving rover, this would be well suited as we need as many measurements to accurately plot the rover position in a time span. But for static…"

"Hi @Luke Wijnberg , I don't understand why you record only 1hz on rover. M8T is capable of 10hz with gps or glonass only Why you don't choose it ?"

"Hi, Interesting to see mapping in Africa. I am in Cameroon, so far just mapping small surfaces with quadcopters. I also get a Skywalker 1800, I am struggling to set it up for survey. @ IronDome : what model is your larger unit ?"

"Hey Luke I get you and I perfectly agree with you, the guys from remote places do not have the luxury of these technologies. How easy was it for you to obtain the CAA and Military clearance? Gary, with eBee yes it took us many flights to cover the…"

"@IronDOME, the reference regarding surveyors in Uganda is specifically targeted those in the Fort Portal region that struggled without reliable internet / electricity. Of course graduates from Kampala would have encountered GPS in their training,…"

IronDOME commented on Luke Wijnberg's blog post Aerial Survey in Uganda
"Nice report. A bit of exaggeration though about my home place. I’m from Tanzania, I don’t think in 2014 there would be a graduate who has not seen a GPS. All in all it was a great job. Considering the area is definitely is high density…"

Walter Volkmann commented on Luke Wijnberg's blog post Emlid Reach for placing GCP
"The beauty of the concept is that the integration is basically only between camera and positioning device, thus keeping navigation and flight control completely ring-fenced from precise positioning. So the point actually is to make precise…"

"What you have is great, Walter and we can wait to see how you integrate it further in to faster moving vehicles. Well done. But the point is to show that for under $600, you can georeference to survey standards using a really simple and cheap tool."

3DroneMapping completes PPK photogrammetry trials

Posted on December 17, 2016 at 6:30am 0 Comments

3DroneMapping has been testing a PPK system for the past year to integrate into our daily workflow. The point of PPK (or Post Processing Kinematic) is not just to improve internal photogrammetric model orientations, but also is general recognised as a way of undertaking full scale surveys at the same accuracy but without having to place time consuming ground control points. 3DroneMapping setup a…

Emlid Reach for placing GCP

Posted on February 29, 2016 at 5:30am 20 Comments

We have been using the L1 only Reach GPS from EMLID for about 2 months. We were first attracted to the fact that it claimed that it was going to be integrated to Pixhawk and would then, via a system of magic, give us centimeter accurate geotagged images, eliminating the need for ground control forever.

While we wait for that to become a reality, we have tried out the Reach as a replacement to our normal survey…
