Camera SDK Library

This directory contains the core GigE camera SDK library required for the USDA Vision Camera System.

Contents

Core SDK Library

• mvsdk.py - Python wrapper for the GigE camera SDK
  • Provides Python bindings for camera control functions
  • Handles camera initialization, configuration, and image capture
  • Critical dependency - Required for all camera operations

Important Notes

⚠️ This is NOT demo code - This directory contains the core SDK library that the entire system depends on for camera functionality.

SDK Library Details

• The mvsdk.py file is a Python wrapper around the native camera SDK
• It provides ctypes bindings to the underlying C/C++ camera library
• Contains all camera control functions, constants, and data structures
• Used by all camera modules in usda_vision_system/camera/

Dependencies

• Requires the native camera SDK library (libMVSDK.so on Linux)
• The native library should be installed system-wide or available in the library path

Usage

This SDK is automatically imported by the camera modules:

# Imported by camera modules
import sys
import os
sys.path.append(os.path.join(os.path.dirname(__file__), "..", "..", "camera_sdk"))
import mvsdk

Demo Code

For camera usage examples and demo code, see the ../demos/ directory:

• cv_grab.py - Basic camera capture example
• cv_grab2.py - Multi-camera capture example
• cv_grab_callback.py - Callback-based capture example
• grab.py - Simple image capture example

Troubleshooting

If you encounter camera SDK issues:

1. Check SDK Installation:

   ls -la camera_sdk/mvsdk.py
   

2. Test SDK Import:

   python -c "import sys; sys.path.append('./camera_sdk'); import mvsdk; print('SDK imported successfully')"
   

3. Check Native Library:

   # On Linux
   ldconfig -p | grep MVSDK
