C++ utilities for working with multiple cameras, including a calibration tool and YOLOv8-based demos.

Configuration

config/config.json contains an example configuration. At runtime the utilities look for a config.json file located in the same directory as the executable. This path can be overridden with the --config flag where available. If the file is missing the program will generate a template with the basic fields, including the new scheme_type and per-camera role.

Camera Modes

Each camera entry in config.json uses a mode field to control how the device operates:

• preview – capture frames for viewing only, detection is disabled.
• detect – run the detection pipeline for the camera.
• calibration – reserve the camera for calibration tasks.

Older configurations that used the preview boolean are still accepted but should be migrated to the new mode field.

Calibration Flow

The yolov8_web_server_calibration utility streams raw camera frames for collecting calibration images. Detection and bounding-box drawing are disabled when the server is started with the --no-draw flag, and the web UI fetches the undistorted preview via /api/preview.mjpg. While calibration is running the video feed shows no detections or overlays.
