Drone,s mosaic processing Error
I have a problem when I am creating mosaic from Drone,s Image in my thesis that is about assessing plantation monitoring by drones. Drone was Phantom 3 Pro , the flight altitude was 70 meter , front overlap was 80 percent , side overlap was 70 percent. near 80 images was captured and all other setting was ok but when I created mosaic with different software like Pix4d mapper or Agisoft or drone deploy or correlated3d , I saw the middle area of mosaic is empty. I thought increasing contrast and image enhancement will help to create complete mosaic but it was not the reason. may I ask you to help me to solve this problem ?

8 年Hi AR HP, I Don't have technical knowledge about flying part. But i feel this may happen due to geotagg issue, we can solve the issue. If possible can you please share some images to [email protected]

8 年AR HP Remember that you should perform, either a new flight with more height and more overlap, or try a new flight "just in the middle part", correctly overlapped to the other 2 parts. For doing properly this overlap with the other 2 good parts, follow the instructions that you can see in the "Figure 5" here: https://support.pix4d.com/hc/en-us/articles/202557459-Step-1-Before-Starting-a-Project-1-Designing-the-Image-Acquisition-Plan-a-Selecting-the-Image-Acquisition-Plan-Type#gsc.tab=0 And you should use a GPS to measure the GCPs. Also be careful of the "Camera Optimization", you have to "Load Optimized Parameters" to get a "low %" of relative difference between initial and optimized internal camera parameters.
