I'd like to automatically save the (.psz) project files at the end of my scripted process so that I can return to them later on and manually edit the project if necessary.  I am currently doing this with "    doc.save(project_path)" at the end of my workflow, however the saved .psz file is very small and can't be opened.  My full current workflow is this:

complete_file = os.path.join('/tmp', 'photoscan.txt')
blockw = 4096
blockh = 4096

app = PhotoScan.Application()
doc = PhotoScan.Document()

chunk = PhotoScan.Chunk()

for image in image_list:
    print('Loading camera = {}'.format(image))
    camera = PhotoScan.Camera()
    camera.open(image)
    chunk.cameras.add(camera)
    count -= 1
    if count == 0:
        break

gc = PhotoScan.GroundControl(chunk)
gc.loadExif()
gc.apply()

crs = PhotoScan.CoordinateSystem()
crs.init('EPSG::4326')  # WSG84
chunk.crs = crs
chunk.projection = crs

try:
    open(complete_file, mode='w').write('matching')
    chunk.matchPhotos(accuracy='high', preselection='ground control')

    open(complete_file, mode='w').write('aligning')
    chunk.alignPhotos()

    # optimise alignment by limiting poor quality matches
    open(complete_file, mode='w').write('restricting point reprojection error')
    chunk.buildPoints(error=1)

    # optimise camera params
    open(complete_file, mode='w').write('optimising point cloud and camera parameters')
    chunk.optimizePhotos()

    open(complete_file, mode='w').write('building dense cloud')
    chunk.buildDenseCloud(quality='high')
    # chunk.decimateModel(100000)

    open(complete_file, mode='w').write('building model')
    chunk.buildModel(surface='height field', faces='high')

    # chunk.model.closeHoles()
    open(complete_file, mode='w').write('fixing topology')
    try:
        chunk.model.fixTopology()
    except:
        pass

    open(complete_file, mode='w').write('building points')
    chunk.buildPoints(error=1)

    open(complete_file, mode='w').write('building texture')
    chunk.buildTexture(blending='mosaic')

    open(complete_file, mode='w').write('exporting report')
    chunk.exportReport(report_path)

    open(complete_file, mode='w').write('exporting model')
    chunk.exportModel(model_path, format='3ds')

    open(complete_file, mode='w').write('exporting points')
    chunk.exportPoints(points_path, format='obj')

    open(complete_file, mode='w').write('exporting ortho')
    chunk.exportOrthophoto(orthophoto_path, blockw=blockw, blockh=blockh, color_correction=False, blending='mosaic', write_kml=True, write_world=True, projection=chunk.projection)

    open(complete_file, mode='w').write('saving project')
    doc.save(project_path)

    open(complete_file, mode='w').write('done' + '\n' + 'success')
    app = PhotoScan.Application()
    app.quit()

except Exception as e:

    open(complete_file, mode='w').write('error' + '\n' + str(e))
    app = PhotoScan.Application()
    app.quit()

The saved .psz file is only 189B and can't be opened after.  Any ideas about how to save the full .psz file so I can open it manually in Photoscan later on would be greatly appreciated.

Thanks

Hello jeremyeastwood,

It seems that in your code chunk is not connected to the document anyhow.

I'd recommend to put doc.chunks.add(chunk) somewhere before saving the proejct. Also you can name the chunk by assigning a new line to chunk.label.
