Struct ChessParams 

#[non_exhaustive]
pub struct ChessParams {
    pub use_radius10: bool,
    pub threshold: f32,
    pub nms_radius: u32,
    pub min_cluster_size: u32,
    pub refiner: RefinerKind,
    pub orientation_method: Option<OrientationMethod>,
}

Low-level ChESS detection parameters consumed by the response and detection stages. The chess-corners facade lowers its DetectorConfig onto this type; depend on it directly when driving the response and detection stages without going through the facade. 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.

threshold: f32

Absolute response floor: a corner is kept when its raw ChESS response exceeds this value (strict >). 0.0 accepts every strictly-positive response — the paper’s contract.

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 center-of-mass on the response map.

orientation_method: Option<OrientationMethod>

Orientation-fit method used to estimate the two grid axes at each detected corner, or None to skip the fit entirely (every descriptor then carries axes: None). Default Some(OrientationMethod::RingFit) fits the parametric two-axis model with robust seeding and calibrated per-axis uncertainties.

Implementations

impl ChessParams

pub const DEFAULT_NMS_RADIUS: u32 = 2

Default non-maximum-suppression half-radius, in pixels. Single source of truth shared with the chess-corners facade’s DetectionParams default.

pub const DEFAULT_MIN_CLUSTER_SIZE: u32 = 2

Default minimum count of positive-response neighbours required to accept a cluster. Single source of truth shared with the chess-corners facade’s DetectionParams default.

pub fn ring_radius(&self) -> u32

Ring radius in pixels selected by Self::use_radius10: 10 when set, 5 otherwise.

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.
