Struct GlobalTransformEstimate 

pub struct GlobalTransformEstimate {
    pub transform: AffineTransform2D,
    pub confidence: f32,
    pub method: TransformEstimationMethod,
    pub computed_at: ViewVersion,
}

A frame-to-reference coordinate transform estimate.

Provided by ViewStateProvider implementations that perform feature matching, optical flow, or PTZ-based modeling.

Fields

transform: AffineTransform2D

The affine transform from current frame coordinates to reference coordinates.

confidence: f32

Confidence in this estimate, in [0.0, 1.0].

method: TransformEstimationMethod

Method used to compute this transform.

computed_at: ViewVersion

ViewVersion at which this transform was computed.

Consumers can compare against the current version to detect staleness.

Implementations

impl GlobalTransformEstimate

pub fn displacement_magnitude(&self) -> f32

Displacement magnitude (in normalized coordinates) implied by the translation component of the transform.

sqrt(tx² + ty²) of the affine matrix.

Trait Implementations

impl Clone for GlobalTransformEstimate

fn clone(&self) -> GlobalTransformEstimate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GlobalTransformEstimate

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

Formats the value using the given formatter.

impl PartialEq for GlobalTransformEstimate

fn eq(&self, other: &GlobalTransformEstimate) -> 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.
