Enum RectToImgMapper

#[non_exhaustive]pub enum RectToImgMapper {
    Global {
        h_img_from_rect: Homography,
    },
    Mesh {
        cells_x: usize,

        cell_h: Vec<Option<Homography>>,
    },
}

Expand description

Mapping from rectified-image coordinates back to original-image coordinates.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Global

A single global homography — appropriate when lens distortion is negligible.

Fields

§h_img_from_rect: Homography

Homography mapping rectified coordinates to image coordinates.

Mesh

A per-cell homography mesh — tolerates lens distortion that a single global fit cannot.

Fields

§cells_x: usize

Number of cells horizontally.

§cells_y: usize

Number of cells vertically.

§px_per_square: f32

Side length of one cell in rectified pixels.

§cell_h: Vec<Option<Homography>>

One homography per cell (row-major); None for cells whose fit failed.

Implementations§

impl RectToImgMapper

pub fn map(&self, p_rect: Point2<f32>) -> Option<Point2<f32>>

Map a rectified-image point back to original-image coordinates.

Returns None for the mesh mapper when p_rect falls outside the cell grid or lands in a cell with no valid homography.
