ODMNode

 Un metodo per automatizzare ODM e' quello di utilizzare NodeODM

 

 In estrema sintesi si mette in esecuzione su un server il docker con la seguente sintassi

 

 docker run -p 3000:3000 opendronemap/nodeodm

 In seguito da un client si puo' usare il seguente script Python per effettuare l'upload automatico di tutte le immagini in un folder e per impostare i parametri di lavoro. Al termine del task sul server i dati saranno reinviati in automatico al client

for dirname, dirnames, filenames in os.walk('./images/'):

for subdirname in dirnames:

files.append(os.path.join(dirname, subdirname))

for filename in filenames:

files.append(os.path.join(dirname, filename))

pprint(files)

# Start a task
