Per chi si fosse perso le puntate precedenti: Parte prima
Adesso passiamo ad installare il programma che ci permetterà, con relativa semplicità, di attivare la videosorveglianza: motion. Si installa con il comando
1
| sudo apt-get install motion |
sudo apt-get install motion
Qualche minuto di pazienza e il programma sarà pronto. Adesso inizia il bello. Si deve configurare il programma, andando a lavorare sul suo elaborato file di configurazione. Qui un esempio (nello specifico quello che uso io, togliendo un po’ delle mille opzioni che ho lasciato inutilizzate)

Paura, eh? Non vi preoccupate, i parametri utili sono semplici ed abbastanza intuitivi, adesso li analizziamo uno per volta. Tutti i parametri che non affronto, semplicemente non li ho utilizzati, nella ricca documentazione trovate tutte le funzioni extra che potete aggiungere al vostro sistema.
Questo dice al programma che quando viene avviato deve rilasciare la console libera e deve funzionare come demone (“servizio”, in lingua Windows). E’ bene tenerlo ad OFF durante tutte le vostre prove, in modo da vedere a video cosa sta combinando il programma e sopratutto se ci sono errori
il file dentro cui saranno salvati tutti i log (quelli che vedete a video con l’impostazione “daemon off” appena vista, per intenderci). Consiglio personale: NON chiamate questo file “motion” o con un nome che contenga la parola “motion”, questo per evitare innumerevoli casini quando andremo a sviluppare l’applicazione
Quante cose devo memorizzare nel file di log? Dopo un po’ di prove, ho raggiungo la conclusione che “7” è il livello adatto per capire cosa sta succedendo, senza morire sommersi di informazioni inutili

Questa è la videocamera che verrà utilizzata per rilevare il movimento, il default è la videocamera che avete appena collegato al Raspberry Pi e che avete provato

| width 768
height 1024 |
width 768
height 1024
Questa è la dimensione del video che verrà ripreso e dei fermo immagine che verranno salvati in caso di movimento. Assicuratevi che siano valori divisibili per 16 e che non superino la risoluzione della videocamera (1920×1080). Più solo alti, più il processore verrà messo sotto stress, ma se sono stroppo bassi perderete dettaglio nella registrazione. Con 1024×768 mi pare di aver trovato un buon compromesso
Quante foto devono essere salvate per ogni secondo? Più il valore è alto più la CPU sarà sotto stress, ma meno dettaglio avrete in caso di movimenti rapidi. L’unica è fare un po’ di tentativi. Per me 4 è un valore buono (vedo la faccia di chi entra in casa tutte le volte)
Se non usate la videocamera del Raspberry Pi, potete collegarvi ad una videocamera IP (ma dovete avere le documentazione)
Questo è un parametro importante. Per identificare il movimento il sistema fa un banale controllo: “quanti pixel sono cambiati dall’immagine precedente all’attuale?”. In un frame da 1024×768 i pixel sono 786.432, la domanda che ci si deve porre è “che percentuale dell’immagine deve cambiare perché io sia avvisato?”. La risposta è solo una: provare e provare
dopo quanti secondi senza movimento devo identificare l’evento come terminato? Questo parametro ci servirà più tardi.
Devo salvare le immagini del movimento? con l’importazione ad “on2 la risposta è “sì, salvale tutte”

Il sistema può anche salvare dei video, nei formati più disparati, per poterlo fare dovere installare un codec MPEG4 o simile, l’ho fatto, ma non mi è tornato utile, non salvo i video, ma solo le immagini
Se volete ottenere una foto ogni “x” secondi, mettete un valore numerico qui, l’immagine verrà salvata anche se non c’è movimento

text_double on
Il sistema metterà in sovraimpressione il testo che deciderete voi, così da identificare l’immgine. La “text_changes” mostra quanti pixel sono cambiati, vi aiuta per capire come impostare il parametro “treshold”. La “text_double” se impostata ad “on” renderà un po’ più leggibili le scritte se l’immagine è ad alta risoluzione

| target_dir /home/pi/Pictures |
target_dir /home/pi/Pictures
Questa è la cartella dove verranno salvate tutte le immagini registrate. Se contate di non cancellarle mai è bene che sia un posto sufficientemente capiente, tipo un disco USB
Il nome che viene assegnato al file salvato, io ho lasciato tutto impostato al default
Volete vedere cosa sta osservando la videocamera? Puntate il browser all’indirizzo http://[indirizzo IP del Raspberry]:8091 ed avrete la risposta. Se non è una cosa che vi interessa, mettete “0” al posto di “8091”. Non so perché, ma su Chrome lo streaming non va, provate con un altro browser prima di impazzire 2 giorni per capire cosa potrebbe non andare bene sulla vostra scheda Raspberry Pi

on_event_end rm /home/pi/Pictures/*.jpg

on_event_end rm /home/pi/Pictures/*.jpg
on_picture_save python /home/pi/tweepy/tweet.py %f
Questa parte è importante! Cosa deve fare il programma quando succede qualcosa? Il cuore della funzionalità è qui.
Partiamo da “on_picture_save”. Ogni volta che un’immagine viene salvata io eseguo uno script in Python(lo vedremo oltre) che prende l’immagine salvata e la twitta (sì, posta l’immagine su twitter, con un apposito account protetto e citando il mio account principale: nessuno oltre me può vedere quell’immagine). Una volta twittata per me è inutile che questa stia sul Raspberry Pi, pertanto, alla fine dell’evento (dopo i secondi indicati nel parametro “event_gap”) il comando “rm /home/pi/Pictures/*.jpg” cancellerà tutte le foto salvate
Bene, abbiamo il file configurato. Ma dove lo mettiamo? Il file si deve chiamare “motion.conf” e deve stare nella cartella “/home/pi/.motion”. Commentate le righe relative agli eventi “on_[qualcosa]” anteponendo un “;” o un “#”, e impostate l’opzione “daemon” a “off”, salvate il file ed eseguite il programma “/home/pi/motion-mmal/motion”
Nota molto bene: in teoria motion parte digitando “motion” da una cartella qualunque, ma in questo caso non trova la videocamera, almeno nel mio caso.
Se tutto va come deve (no, la prima volta non va mai tutto come deve) il programma partirà, vi dirà che ha attivato la videocamera che he (se lo avete attivato) ha anche attivato il server web per lo streaming, una cosa del genere. Il LED rosso della videocamera si accenderà indicando che è attiva.

Adesso provate a passare davanti alla videocamera con la mano, voi stessi o banalmente generate un movimento davanti ad essa ed eco che il log vi dirà (sì, il file di log parla ed è buona norma ascoltarlo, sempre) una cosa del genere

Terminate l’esecuzione del programma con un bel Ctrl+C andare a vedere nella cartella /home/pi/Pictures/ la presenza dei file salvati. Questi conterranno il movimento rilevato.
