Add photos to the chunk

[Alexey Pasumansky]

Hello magic,

I have updated the second part of the script - now it splits the cameras to the groups inside the single (active) chunk:

Code: [Select]

doc = PhotoScan.app.document
chunk = doc.addChunk()
chunk.label = "New Chunk"

# Ajout de photos -add photos 1st chunk
path_photos = PhotoScan.app.getExistingDirectory("main folder:")
image_list = os.listdir(path_photos)
photo_list = list()
for photo in image_list:
    if photo.rsplit(".",1)[1].lower() in  ["jpg", "jpeg", "tif", "tiff"]:
        photo_list.append("/".join([path_photos, photo]))
chunk.addPhotos(photo_list)
print("- Photos ajoutées")


time_table = list()
for camera in chunk.cameras:
time = camera.photo.meta['Exif/DateTimeOriginal'].split(" ")[1][:-3].replace(":", ".")
time = float(time)
time = time // 1 + (time  - time // 1) * 100 / 60
time_table.append(time)

time_table.sort()
limits = (time_table[0], time_table[-1])
interval = 5 / 60. #five minute interval
start = limits[0]

while True:

empty = True
new_group = chunk.addCameraGroup()
finish = start + interval
new_group.label = "{:d}:{:d} - {:d}:{:d}".format(int(start // 1), int((start - start // 1) * 60),
int(finish // 1), int((finish - finish // 1) * 60))#####
for camera in list(chunk.cameras):
time = float(camera.photo.meta['Exif/DateTimeOriginal'].split(" ")[1][:-3].replace(":", "."))
time = time // 1 + (time  - time // 1) * 100 / 60

if start <= time < start + interval:
camera.group = new_group
empty = False

start += interval

if empty:
chunk.remove(new_group)
if start > limits[-1]:
break

print("script finished")

Hello magic,

I can suggest the following:

Code: [Select]

import PhotoScan

chunk = PhotoScan.app.document.chunk
step = 5

for i in range(len(chunk.cameras)):
    camera = chunk.cameras[i]
    if not (i + 1) % step:
        camera.enabled = False
    else:
        camera.enabled = True
print("Every {:d} camera disabled.".format(step))

Hi Alexey

Seems good but dsnt work, its something like no action inside , return print but any cameras picked in our list

[magic]

Hello magic,

I have forgotten the camera assignment:

Code: [Select]

    camera = chunk.cameras[i]See the updated script in the post above.

Hi,

I try also to add photos to my chunk but it doesn't work.
The error it's "Empty file list".
But in my folder there are many pictures and their extension is .jpg
So I don't understand what's wrong with my script.
I put my script in attached file.
So, If you have some times, can you help me to fixe my problem.
Thanks,
Eva Ingenior Student

Hello Eva,

Actually in your script the part with the photo_list populating code is missing. It should be in between lines 40 and 41, similar to the example in this thread:

Code: [Select]

# Préciser le dossier contenant les images
path_photos = PhotoScan.app.getExistingDirectory("Specifier le chemin d'accès contenant les images: ")
image_list = os.listdir(path_photos)
photo_list = list()
for photo in image_list:
    if photo.rsplit(".",1)[1].lower() in  ["jpg", "jpeg", "tif", "tiff"]:
        photo_list.append("/".join([path_photos, photo]))
chunk.addPhotos(photo_list)

Thanks a lot, now it works.
I have another question to improve my script. Indeed, I would like to specify by the person who uses the script the coordinate system. In my script, it works, a window appears and asks to precise the coordinate system. Nevertheless, there is no coordinate system to be choosen except to search in a file in the computer. But how to access to all the coordinate system as like as the window when we go to the chunk and reference settings.

I hope it's clear, it's not always easy to explain in english the problem.
I put again in attached file my script reviewed.

Thanks again for your wonderful help,
Have a nice day,
Eva

Hello Eva,

When you are using

Code: [Select]

crs = PhotoScan.app.getCoordinateSystem("Select Coordinate System", doc.chunk.crs)the compact coordinate system selection dialog appears with the recently used systems (the default system will be current coordinate system of the chunk (doc.chunk.crs), but clicking on "More..." option you will be able to open the common coordinate selection dialog, where you can find the required system from the list. Only clicking on Load button will suggest to locate the PRJ file in the file browser.

Hi Alexey

Have another problem
Now i want to select enabled cameras (all in my chunk without disabled) and iv tried this

 

Code: [Select]

####
import PhotoScan
chunk = PhotoScan.app.document.chunk
for f in os.listdir(chunk.cameras):
   if re.match(camera.enabled = True, f):
       print f
######


import PhotoScan
chunk = PhotoScan.app/document.chunk
list_of_files = os.listdir(os.getcwd(chunk.cameras))
for each_file in list_of_files:
    if each_file.startswith(camera.enabled == True):
        print (each_file)

####
import PhotoScan
chunk = PhotoScan.app.document.chunk
chunk = doc.chunk
for i in os.listdirrange(len(chunk.cameras)):
    if os.path.isfile(os.path.join(path,i)) and camera.enabled == True in i:
        files.append(i)


No one of code above works , any suggestion Alexey ??

Hello magic,

If you need to select the camera instances that are already added to the active chunk, you do not need to look for some files in the folders:

Code: [Select]

chunk = PhotoScan.app.document.chunk
for camera in chunk.cameras:
    if camera.enabled:
        camera.selected = True
    else:
        camera.selected = False

Iv tried it before with small keyboard mistake ^^
