|
||||
|
||||
## Current Configuration
|
||||
|
||||
The current config.json for camera2 includes:
|
||||
|
||||
```json
|
||||
{
|
||||
"name": "camera2",
|
||||
"machine_topic": "vibratory_conveyor",
|
||||
"storage_path": "/storage/camera2",
|
||||
"exposure_ms": 0.5,
|
||||
"gain": 0.3,
|
||||
"target_fps": 0,
|
||||
"enabled": true,
|
||||
"auto_start_recording_enabled": true,
|
||||
"auto_recording_max_retries": 3,
|
||||
"auto_recording_retry_delay_seconds": 2,
|
||||
"sharpness": 0,
|
||||
"contrast": 100,
|
||||
"saturation": 100,
|
||||
"gamma": 100,
|
||||
"noise_filter_enabled": false,
|
||||
"denoise_3d_enabled": false,
|
||||
"auto_white_balance": false,
|
||||
"color_temperature_preset": 6500,
|
||||
"wb_red_gain": 1.01,
|
||||
"wb_green_gain": 1.0,
|
||||
"wb_blue_gain": 0.87,
|
||||
"anti_flicker_enabled": false,
|
||||
"light_frequency": 1,
|
||||
"bit_depth": 8,
|
||||
"hdr_enabled": false,
|
||||
"hdr_gain_mode": 0
|
||||
}
|
||||
```
|
||||
|
||||
## Key Differences from Camera1 (Blower Camera)
|
||||
|
||||
1. **RGB Gain Tuning**: Camera2 has custom RGB gains (R:1.01, G:1.00, B:0.87) vs Camera1's balanced gains (all 1.0)
|
||||
2. **Sharpness**: Camera2 has sharpness disabled (0) vs Camera1's normal sharpness (100)
|
||||
3. **Exposure/Gain**: Camera2 uses lower exposure (0.5ms) and gain (0.3x) vs Camera1's higher values (1.0ms, 3.5x)
|
||||
4. **Anti-Flicker**: Camera2 has anti-flicker disabled vs Camera1's enabled anti-flicker
|
||||
|
||||
## Notes
|
||||
|
||||
1. **Custom White Balance**: Camera2 uses manual white balance with custom RGB gains, suggesting specific lighting conditions or color correction requirements for the conveyor monitoring.
|
||||
|
||||
2. **No Sharpening**: Sharpness is set to 0, indicating the raw image quality is preferred without artificial enhancement.
|
||||
|
||||
3. **Minimal Noise Reduction**: Both 2D and 3D denoising are disabled, prioritizing image authenticity over noise reduction.
|
||||
|
||||
4. **Dead Pixel Correction**: Enabled to handle any defective pixels on the sensor.
|
||||
|
||||
5. **Lower Sensitivity**: The lower exposure and gain settings suggest better lighting conditions or different monitoring requirements compared to the blower camera.
|
||||
|
||||
## Camera Preview Enhancement
|
||||
|
||||
**Important Update**: The camera preview/streaming functionality has been enhanced to apply all default configuration settings from config.json, ensuring that preview images match the quality and appearance of recorded videos.
|
||||
|
||||
### What Changed
|
||||
|
||||
Previously, camera preview only applied basic settings (exposure, gain, trigger mode). Now, the preview applies the complete configuration including:
|
||||
|
||||
- **Image Quality**: Sharpness, contrast, gamma, saturation
|
||||
- **Color Processing**: White balance mode, color temperature, RGB gains
|
||||
- **Advanced Settings**: Anti-flicker, light frequency, HDR settings
|
||||
- **Noise Reduction**: Filter and 3D denoising settings (where supported)
|
||||
|
||||
### Benefits
|
||||
|
||||
1. **WYSIWYG Preview**: What you see in the preview is exactly what gets recorded
|
||||
2. **Accurate Color Representation**: Manual white balance and RGB gains are applied to preview
|
||||
3. **Consistent Image Quality**: Sharpness, contrast, and gamma settings match recording
|
||||
4. **Proper Exposure**: Anti-flicker and lighting frequency settings are applied
|
||||
|
||||
### Technical Implementation
|
||||
|
||||
The `CameraStreamer` class now includes the same comprehensive configuration methods as `CameraRecorder`:
|
||||
|
||||
- `_configure_image_quality()`: Applies sharpness, contrast, gamma, saturation
|
||||
- `_configure_color_settings()`: Applies white balance mode, color temperature, RGB gains
|
||||
- `_configure_advanced_settings()`: Applies anti-flicker, light frequency, HDR
|
||||
- `_configure_noise_reduction()`: Applies noise filter settings
|
||||
|
||||
These methods are called during camera initialization for streaming, ensuring all config.json settings are applied.
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
Additional parameters that could be added to support all graphic processing features:
|
||||
|
||||
- `rotation_angle`: Image rotation (0, 90, 180, 270 degrees)
|
||||
- `lens_distortion_correction`: Enable/disable lens distortion correction
|
||||
- `dead_pixel_correction`: Enable/disable dead pixel correction
|
||||
- `flat_fielding_correction`: Enable/disable flat fielding correction
|
||||
- `mirror_horizontal`: Horizontal mirroring
|
||||
- `mirror_vertical`: Vertical mirroring
