I am having a hard time getting good results from a project where we combined terrestrial, grid and point of interest data into a decent orthoplane projection.
We are following the processes outlined in the multiproject processing, and in creating the orthoplane projections. But we’re consistently getting problems where the final images are not “connected” correctly? I’m not sure how to describe the problem. It’s as if the program is choosing at random which photos to use to acquire the data.
We managed to bash together something that looks decent for one elevation, but then experienced a crash, then loss of data. I have a couple theories and questions that I’d like to run by the community because I’ve run up against the wall of my knowledge.
Here’s a link to the 3D model of the project. https://sketchfab.com/models/f98df51aea794496a2b3325f29c2e031 (you can see that the 3D turned out okay…)
This is a look at a “good” projection. Even though there are some issues this is acceptable for now. (the future will be better)
The main issue in these is the transition the images are making between the Terrestrial and Aerial image data… so darn confusing, and the ghosting.
I have a couple theories about what’s happening, but really I just have these questions.
- Is there anyway to tell Pix4D to utilize certain images over others for the orthoplanes? Like a prefer terrestrial images… something? So I can avoid the really bad transition line?
- Is the image fidelity related to the quality of the point cloud?
- Why, if an object is _Masked _or Carved out from an image would the object still show in the Orthoplane?
- Does a higher number of MTPs affect the quality of an orthplane reconstruction (specifically looking at the wavy building cap in the “good” reconstruction)?
- Would I get a better orthographic projection by having a super high quality 3D model constructed, and then rendering out the elevations? (this means I don’t get a “to scale” elevation, but I’m looking for good quality, not to scale).
So, I’m not sure what other bits of information to add to this post, so I’ll just let some questions come to me. This is a project we’re trying to turn around fast. I’d be okay with just getting to the level of quality of the “good” facade.
