Vision-based inspection with a camera gantry

Challenge

Stock had to be reconciled with the target state in the system on a regular basis. Counting and scanning by hand was slow and error-prone, especially across large areas.

Technology

  • Python
  • FastAPI
  • Kotlin
  • CameraX
  • ESP32
  • Feldorientierte Regelung (FOC)
  • WebSocket
  • Bilderkennung

Requirements

  • Automatic capture of barcodes and QR codes across an entire area
  • Target/actual reconciliation against ERP data
  • Two-axis camera positioning
  • Safe behaviour with uncalibrated axes
  • Live dashboard for the results

Approach

  1. 01Camera gantry with a field-oriented-control BLDC axis and a stepper axis
  2. 02ESP32 firmware for positioning, connected via Wi-Fi WebSocket
  3. 03Android app as camera and control node
  4. 04Server for orchestration, image recognition, reconciliation and dashboard
  5. 05Interface contracts as the single source for all subsystems; third generation of a solution developed since 2023
