Axis Time-Laps Script Teil 1

Einleitung

Diese Script dient dem Download und der ersten Verarbeitung der Bilder vom der Kamera.

Funktionen

func_check

Die Funktion "func_check" dient der Überprüfung, ob die benötigten Programme alle Installiert sind. Falls ein Programm nicht installiert ist, wird eine entsprechende Fehlermeldung ausgegeben und das Script wird beendet. Folgenden Programme werden benötigt:

  • imagemagick
  • curl
  • whipthail
#Variable not editabel
var_convert="/usr/bin/convert"
var_curl="/usr/bin/curl"
var_whiptail="/usr/bin/whiptail"
var_temp_ip="192.168.1.2"

#Function

function func_check() {
    if [[ ! -x $var_convert ]]; then
        echo "Program \"imagemagick\" is not install\n\
        Please install \"imagemagick\""
        exit
    fi
    if [[ ! -x $var_curl ]]; then
        echo "Program \"curl\" is not install\n\
        Please install \"curl\""
        exit
    fi
    if [[ ! -x $var_whiptail ]]; then
        echo "Program \"whiptail\" is not install\n\
        Please install \"whiptail\""
        exit
    fi
}

func_image

Die Funktion "func_image" läde via "curl" das aktuelle Bild der Kamera herunter und bearbeite dies entsprechenden weiter.

Bei der ersten Variabele "var_output_image_name" wird der Name des Zielbildes definiert. Als Name wird die Zeit und Datum nach der UNIX Zeit gewählt.

Danach wird das Bild von der Kamera bezogen, die IP-Adresse bzw. der Hostname wird über die Option "-c" definiert. Die Auflösung des Bild wird über die Optionen "-r" definiert, hier bei muss der Wert auf die Kamera angepasst werden

function func_image() {
    var_output_image_name=$(date +%s)
    var_date_image=$(date +"%Y.%m.%d %H:%M")
    curl --digest -u "$var_cam_user:$var_cam_pw" -s \
    --output $var_output_image_name.jpg \
    http://$var_cam_host/axis-cgi/jpg/image.cgi?resolution=$var_image_resolution
    convert $var_output_image_name.jpg \
    -pointsize 30 -fill white -undercolor '#00000080' \
    -gravity NorthWest -annotate +20+20 \
    "$var_date_image" $var_output_image_name.jpg
    convert $var_output_image_name.jpg \
    $var_logo -gravity southeast -geometry +10+10 \
    -composite $var_output_image_name.jpg
}

func_metadate

Die Funktion "func_metadate" bearbeite mittels "exiftool" die Metadaten des Bildes, es wird nur das Copyright ergänzt. Das Copyright wird mit der Option "-C" angegeben.

function func_metadate() {
    if [[ -n $var_copyright ]]; then
        exiftool -m -overwrite_original -copyright="$var_copyright" $var_output_image_name.jpg
    fi
}

func_help

Die Funktion "func_help" zeigt und beschreibt die möglichen Optionen.

function func_help() {
    echo -e "Usage: axis_timelaps_image [OPTIONS]\n\
    Options:\n\
      -c     IP-Address or Hostname from Axis Networkcamera\n\
      -u     Username from Cam\n\
      -p     Passwort for User from Cam\n\
      -r     Resolution for Image\n\
      -l     Logo\n\
      -C     Copyright Information\n\
      -o     Output folder\n\
      -i     Interactive Configuration"
    exit
}
