Struct TrackResult 

pub struct TrackResult {
    pub pos: (f32, f32),
    pub status: TrackStatus,
    pub error: f32,
}

Per-point result of calc_optical_flow_ex.

Coordinate convention

Positions are in level-0 (full resolution) pixel coordinates. The origin is the center of the top-left pixel, x grows to the right and y downwards; this matches crate::good_features_to_track and bilinear sampling throughout the crate.

Fields

pos: (f32, f32)

Tracked position in the next frame.

status: TrackStatus

Why tracking ended the way it did.

error: f32

Mean absolute photometric residual over the window at the final position, in 8-bit intensity units.

Comparable across points regardless of window_size; intended for downstream outlier gating. It is f32::INFINITY when no residual could be measured (the window was out of bounds).

Trait Implementations

impl Clone for TrackResult

fn clone(&self) -> TrackResult

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for TrackResult

impl Debug for TrackResult

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for TrackResult

fn eq(&self, other: &TrackResult) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
