agtek_-_photogrammetry_-_desktop_and_web

This is an old revision of the document!


As the drone story progresses it's becoming more apparent that AGTEK should probably have a photogrammetry processing story to avoid dependence on any one vendor and to simplify the offering for heavy construction. We do not plan to write the photogrammetry engine but instead would pursue a licensing deal through Hexagon/Infinity, Pix4D, Drone Deploy or some other vendor.

Desktop vs Web

Advantages of Desktop

  Don't have to upload and download lots of files over sketchy connections in the field. Upload is typically slow on most connections
  Faster response on some sites
  Visibility of flight holes and mistakes
  Fast map rendering/ uploading downsampled results rather than huge files
  
Advantages of web
 Deferred processing without interaction
 Modern
 Doesn't require a fast computer/ could even be a phone or tablet
 

Advantages of roll our own

  • Fewer choices required of user = Simpler
  • Using Existing AGTEK data for feedback prior to processing or after
  • Changes in order and optimization of data flow.
    • Give the user an orthomap first instead of last even if it's not as efficient.
    • Make assumptions on RTK quality for creating fast picture and uploading to SmartDirt fast
    • Selective downsampling and use of jpg for orthos for size and speed
    • Better control of GCP process/autopopulating/lining up with local coordinates
  • Less vulnerable to vendor changes or miss steps
  • Adjusting for elevation better than GCPs

What to charge - Subscription

Web equivalent and possible interchangability of data between sources

Basic Construction processing Steps

  • New - Name here or later?
  • Load Pictures - display on map/with plansheets/takeoff (what other info needed. Coverage approximation vs perimeters?
  • Set Units, State Plane coordinates system from LL on picture plus user choice on units.
  • Feed GCP(s) for either alignment or elevation point or Elevation Registration area/ allows non-RTK workflow
  • Press Process
  • Do overall quick ortho Map first for visuals, then do steps for surfaces, adjustments for reg areas
  • Upload results in background or update ADF Files in background, Simplified data structure storage.
  • Save project results allow for reprocessing saved to different location
