Für den OCR-Integrationstest sind Tesseract mit `deu`/`eng` und `pdftotext` aus Poppler erforderlich; ohne diese Programme wird er übersprungen. Bei Verwendung der virtuellen Umgebung zuerst `. .venv-opencv/bin/activate` ausführen. Die Tests simulieren `scanimage`, erstellen echte PDFs und prüfen Duplex-/Simplex-Stapel, Seitenreihenfolge, Auflösung, leeren Einzug, Papierstau, beschädigte Seiten, Dateinamen und OpenCV-Ausfälle. Bildtests prüfen die Hintergrundbereinigung bei geraden und schrägen Bons sowie den Erhalt von Text, farbigen Logos und vollständigen Seiten. Der OCR-Test liest die tatsächliche PDF-Textschicht einschließlich leerer Rückseiten aus. Ein Test mit angeschlossenem iX1600 bleibt zusätzlich erforderlich. Hardwareprüfung am 17.09.2026: ScanSnap iX1600 per USB unter Linux Mint 22.3 mit SANE 1.2.1. Zwei A4-Blätter wurden mit 300 dpi in Farbe beidseitig gescannt; das erzeugte PDF enthält vier A4-Seiten in der Reihenfolge Vorderseite/Rückseite. Alle vier Seiten wurden visuell geprüft. Der Test umfasste den lokalen Agenten bis zur PDF-Erstellung; der FEDEO-Upload wird separat mit einem simulierten Dateispeicher getestet. diff --git a/agents/fedeo-device-agent/scripts/build-installer.mjs b/agents/fedeo-device-agent/scripts/build-installer.mjs index 26b888c8..92ebc12b 100644 --- a/agents/fedeo-device-agent/scripts/build-installer.mjs +++ b/agents/fedeo-device-agent/scripts/build-installer.mjs @@ -14,7 +14,7 @@ async function filesUnder(directory) { const packageJson = JSON.parse(await readFile(path.join(root, 'package.json'), 'utf8')) const paths = [ ...(await filesUnder('dist')).filter(file => file.endsWith('.js')), - 'scripts/scan_document.py', 'scripts/opencv_postprocess.py', 'scripts/setup-opencv.sh', + 'scripts/scan_document.py', 'scripts/scan_background.py', 'scripts/opencv_postprocess.py', 'scripts/setup-opencv.sh', 'requirements-opencv.txt', ] const files = Object.fromEntries(await Promise.all(paths.map(async file => [file, (await readFile(path.join(root, file))).toString('base64')]))) diff --git a/agents/fedeo-device-agent/scripts/install-linux.sh b/agents/fedeo-device-agent/scripts/install-linux.sh index 10f80445..fec53ad2 100644 --- a/agents/fedeo-device-agent/scripts/install-linux.sh +++ b/agents/fedeo-device-agent/scripts/install-linux.sh @@ -25,17 +25,22 @@ FEDEO_SETUP_UNIT="fedeo-device-agent-$FEDEO_SETUP_ID.service" FEDEO_SETUP_UNITS="${XDG_CONFIG_HOME:-$HOME/.config}/systemd/user" echo 'FEDEO Scan-Agent wird für diesen Benutzer eingerichtet.' -if ! command -v node >/dev/null || ! command -v scanimage >/dev/null || ! python3 -c 'import PIL' >/dev/null 2>&1; then +fedeo_processing_ready() { + python3 -c 'import PIL, cv2, numpy' >/dev/null 2>&1 && + tesseract --list-langs 2>/dev/null | grep -qx deu && + tesseract --list-langs 2>/dev/null | grep -qx eng +} +if ! command -v node >/dev/null || ! command -v scanimage >/dev/null || ! fedeo_processing_ready; then if ! command -v apt-get >/dev/null; then - echo 'Bitte Node.js >= 20, SANE (scanimage), Python 3 und Pillow installieren und das Skript erneut starten.' >&2 + echo 'Bitte Node.js >= 20, SANE, Python/Pillow/OpenCV sowie Tesseract mit Deutsch/Englisch installieren und das Skript erneut starten.' >&2 exit 1 fi echo 'Fehlende Systempakete werden über apt installiert (sudo benötigt).' sudo apt-get update - sudo apt-get install -y nodejs sane-utils python3-pil + sudo apt-get install -y nodejs sane-utils python3-pil python3-opencv tesseract-ocr tesseract-ocr-deu tesseract-ocr-eng fi node -e 'if (Number(process.versions.node.split(".")[0]) < 20) { console.error("Node.js >= 20 wird benötigt.
