Detailed Description

Clean abstraction for motion detection results.

Separates motion detection logic from visualization. This class acts as a "Snapshot" of a single frame's motion analysis, providing the geometric data required to draw AR overlays or move servos.

Constructor & Destructor Documentation

MotionData() [1/2]

MotionData::MotionData ( )

inline

Default Constructor: Create empty motion data.

Note

Used to initialize state when no motion has been processed yet.

MotionData() [2/2]

MotionData::MotionData ( int centroid_x, int centroid_y, int frame_width, int frame_height, int pixel_count )

inline

Parameterized Constructor: Create motion data from algorithm output.

Parameters

centroid_x	The X coordinate of the motion "blob" center.
centroid_y	The Y coordinate of the motion "blob" center.
frame_width	The resolution width used during analysis.
frame_height	The resolution height used during analysis.
pixel_count	The quantity of pixels that exceeded the sensitivity threshold.

Member Function Documentation

get_centroid_x()

int MotionData::get_centroid_x ( ) const

inline

Get motion centroid X coordinate.

Returns

X pixel coordinate (0 if no motion).

get_centroid_y()

int MotionData::get_centroid_y ( ) const

inline

Get motion centroid Y coordinate.

Returns

Y pixel coordinate (0 if no motion).

get_frame_height()

int MotionData::get_frame_height ( ) const

inline

Get the height of the frame processed.

Returns

Source height in pixels (e.g., 240 for QVGA).

get_frame_width()

int MotionData::get_frame_width ( ) const

inline

Get the width of the frame processed.

Returns

Source width in pixels (e.g., 320 for QVGA).

get_pixel_count()

int MotionData::get_pixel_count ( ) const

inline

Get the volume of detected motion.

Returns

Total count of pixels that changed between frames.

is_detected()

bool MotionData::is_detected ( ) const

inline

Check if valid motion was detected in this snapshot.

Returns

true if the pixel_count met the minimum algorithm threshold.
