programatically set coordinates of automatically detected ground control markers

[beerockxs2]

Hi there,

I'm trying to set the coordinates of my detected groudn control markers programmatically, and it's not working.
Here's the code I'm using:

    chunk.detectMarkers('12bit',95)
    for marker in chunk.markers:

        gcl = PhotoScan.GroundControlLocation(chunk,marker)
        if marker.label == "target 373":
            print("setting coord for marker 373")
            gcl.coord = {357694.233,5609773.51639,227.900330}

The detection does work, the coordinate setting not. What do I need to change?

Hello beerockxs2,

And what is the console output message for this script?

Auto detected markers are created as not enabled and without coordinates. The enabled and coord properties are not accessible through python until the markers have been assigned some coordinates. It looks like you have to manually enable the markers by checking the boxes, which will initialise them with 0,0,0 before your script will work.

Hello beerockxs2,

And what is the console output message for this script?

There is no output regarding the markers, photo matching, image alignment, dense cloud and model building work as normal, but the detected markers stay disabled and have no coordinates assigned to them.

Hello beerockxs2,

I think you should do the following:

Code: [Select]

gc = chunk.ground_control
locations = gc.locations
for marker in chunk.markers:
   locations.add(marker)
   if marker.label == "target 373":
      locations[marker].coord = ([357694.233, 5609773.51639, 227.900330])

ground_control.apply()
PhotoScan.app.update()

ground_control.apply()
PhotoScan.app.update()


With a minor change (gc.apply() instead of ground_control.apply()) this worked just fine. Thanks for the quick response!
