Struct ChessParams 

#[non_exhaustive]
pub struct ChessParams {
    pub use_radius10: bool,
    pub descriptor_use_radius10: Option<bool>,
    pub threshold_rel: f32,
    pub threshold_abs: Option<f32>,
    pub nms_radius: u32,

}

Tunable parameters for the ChESS response computation and corner detection.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

use_radius10: bool

Use the larger r=10 ring instead of the canonical r=5.

descriptor_use_radius10: Option<bool>

Optional override for descriptor sampling ring (r=5 vs r=10). Falls back to use_radius10 when None.

threshold_rel: f32

Relative threshold as a fraction of max response (e.g. 0.2 = 20%).

threshold_abs: Option<f32>

Absolute threshold override; if Some, this is used instead of threshold_rel.

nms_radius: u32

Non-maximum suppression radius (in pixels).

min_cluster_size: u32

Minimum count of positive-response neighbors in NMS window to accept a corner (rejects isolated noise).

refiner: RefinerKind

Subpixel refinement backend and its configuration. Defaults to the legacy center-of-mass refiner on the response map.

orientation_method: OrientationMethod

Orientation-fit method used to estimate the two grid axes at each detected corner. Default OrientationMethod::RingFit fits the parametric two-axis model with robust seeding and calibrated per-axis uncertainties.

Implementations

impl ChessParams

pub fn ring_radius(&self) -> u32

pub fn descriptor_ring_radius(&self) -> u32

pub fn ring(&self) -> RingOffsets

pub fn descriptor_ring(&self) -> RingOffsets

Trait Implementations

impl Clone for ChessParams

fn clone(&self) -> ChessParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChessParams

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

Formats the value using the given formatter.

impl Default for ChessParams

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ChessParams

where ChessParams: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ChessParams

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

impl Serialize for ChessParams

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
