Fotogrammetria
Re: Fotogrammetria
Sono riuscito ad ottenere qualcosa di quasi decente. Il mezzo c'è ma manca una buona fotocamera ed un computer più potente per l'elaborazione video!

Re: Fotogrammetria
quanto tempo ci ha messo autodesk a restituirti l'elaborazione? io con la versione mobile (iphone) ho aspettato anche diversi giorni per un'elaborazione derivante da 40 fotogrammi

Re: Fotogrammetria
Se elimini lo sfondo alleggerisci di parecchio il processo di rending. Hai usato la gopro? Con una buona compatta probabilmente il risultato sarebbe migliore. Non servono foto con una elevata risoluzione. Oltre i 5 Mega pixel appesantisci inutilmente il rendering. Quindi anche una compatta economica va bene magari canon cosi' puoi modificare il firmware e programmarla per fare foto ad intervalli

Re: Fotogrammetria
Questo è il risultato delle foto fatte ieri. La porzione di terreno è più ampia. Ho usato una macchina fotografica Canon con firmware modificato che mi ha permesso di avere un risultato migliore del precedente (anche se con una risoluzione più bassa) perché si vedono i rilievi della vegetazione e come la pista sia più in alto rispetto alla parte circostante.

Re: Fotogrammetria
il fw modificato oltre a darti la possibilità degli scatti sequenziali, cosa altro aggiunge?
