calib-targets-core 0.3.2

//! Core types and utilities for calibration target detection.
//!
//! This crate is intentionally small and purely geometric. It does *not*
//! depend on any concrete corner detector or image type.
//!
//! ## Quickstart
//!
//! ```
//! use calib_targets_core::{Corner, TargetDetection, TargetKind};
//! use nalgebra::Point2;
//!
//! let corner = Corner {
//!     position: Point2::new(10.0, 20.0),
//!     orientation: 0.0,
//!     orientation_cluster: None,
//!     strength: 1.0,
//! };
//!
//! let detection = TargetDetection {
//!     kind: TargetKind::Chessboard,
//!     corners: Vec::new(),
//! };
//!
//! println!("{:?} {}", corner.position, detection.corners.len());
//! ```
//!
//! ## Includes
//!
//! - Homography estimation and warping helpers.
//! - Lightweight grayscale image views and sampling.
//! - Grid alignment and target detection types.
