Detailed Description

Handles auto-calibration of projector overlap using a camera.

Detailed Description This class uses computer vision to detect misalignment between two projectors. It analyzes camera-captured images using SIFT feature detection and FLANN-based matching to calculate horizontal displacement between left and right projected images.

Public Member Functions:

• init(camera_index=0): Constructor
• capture_image(): Captures frame from camera
• calculate_overlap(img_left, img_right): Calculates overlap using SIFT
• simulate_calibration(image_width, current_overlap): Simulates calibration

Public Attributes:

• camera_index: Camera device index
• sift: SIFT feature detector instance
• flann: FLANN-based feature matcher

Constructor & Destructor Documentation

__init__()

calibration.CalibrationManager.__init__	(		self,
		int	camera_index = 0
	)

Constructor & Destructor Documentation.

Initializes the calibration manager.

Parameters

camera_index

Camera device index (default: 0)

Member Function Documentation

calculate_overlap()

Optional[int] calibration.CalibrationManager.calculate_overlap	(		self,
		np.ndarray	img_left,
		np.ndarray	img_right
	)

Member Function Documentation.

Calculates horizontal overlap between two images using SIFT features.

Parameters

img_left	Image from left projector only
img_right	Image from right projector only

Returns

Horizontal overlap error in pixels, or None if insufficient features

Calculates the horizontal overlap between two images using SIFT features.
img_left: The captured image when ONLY the left projector is on.
img_right: The captured image when ONLY the right projector is on.

capture_image()

Optional[np.ndarray] calibration.CalibrationManager.capture_image

(

self

)

Member Function Documentation.

Captures a single frame from the camera.

Returns

Captured frame as numpy array, or None if capture fails

Captures a single frame from the camera.
Returns None if capture fails.

simulate_calibration()

int calibration.CalibrationManager.simulate_calibration	(		self,
		int	image_width,
		int	current_overlap
	)

Member Function Documentation.

Simulates the calibration process for testing.

Parameters

image_width	Input image width (unused)
current_overlap	Current overlap value

Returns

Suggested overlap adjustment in pixels

Simulates the calibration process.
Returns the suggested adjustment to the overlap.
