1//! Core types and utilities for calibration target detection.
2//!
3//! This crate is intentionally small and purely geometric. It does *not*
4//! depend on any concrete corner detector or image type.
5//!
6//! ## Quickstart
7//!
8//! ```
9//! use calib_targets_core::{Corner, TargetDetection, TargetKind};
10//! use nalgebra::Point2;
11//!
12//! let corner = Corner {
13//!     position: Point2::new(10.0, 20.0),
14//!     orientation: 0.0,
15//!     orientation_cluster: None,
16//!     strength: 1.0,
17//! };
18//!
19//! let detection = TargetDetection {
20//!     kind: TargetKind::Chessboard,
21//!     corners: Vec::new(),
22//! };
23//!
24//! println!("{:?} {}", corner.position, detection.corners.len());
25//! ```
26//!
27//! ## Includes
28//!
29//! - Homography estimation and warping helpers.
30//! - Lightweight grayscale image views and sampling.
31//! - Grid alignment and target detection types.
