Fields§

§h_img_from_rect: Homography

Maps rectified coordinates to image coordinates.

§h_rect_from_img: Homography

Maps image coordinates to rectified coordinates.

§min_i: i32

Grid bounding box (with margin) in corner index space.

§min_j: i32§max_i: i32§max_j: i32§px_per_cell: f32

Rectified pixels per grid cell.

§rect_width: usize

Implementations§

impl GridHomography

pub fn from_corners( corners: &HashMap<GridIndex, Point2<f32>>, px_per_cell: f32, margin_cells: f32, ) -> Result<Self, GridRectifyError>

Compute a global homography from grid corners to a rectified coordinate system.

corners: map from grid index to image position.
px_per_cell: rectified pixels per grid cell.
margin_cells: extra margin around the grid bounding box (in cell units).

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

Map a point from rectified space to image space.

pub fn img_to_rect(&self, p_img: Point2<f32>) -> Point2<f32>

Map a point from image space to rectified space.
