Documentation#
This section provides the conceptual and mathematical background for weitsicht: coordinate systems, camera models,
image types, transformations, and mapper (ground model) assumptions.
Basics#
Basics about geo-referenced images.
Single-image pixel → 3D mapping by ray–surface intersection.
Definitions#
Important
This section is critical on how input data need to be defined.
XY definition for pixels
Camera CRS definition used
Rotation matrix basics and common OPK / AZK (APK) notations.
Perspective Image#
Basics on perspective images
Pinhole Model and Distortion
Ortho Imagery#
Rectified image in orthographic view.
Mapper#
Constant-height plane (fast, flat approximation).
Raster-based ground model (rasterio), terrain-aware intersections.
In-memory raster window backend with bilinear patch intersections.
Triangle mesh intersections (trimesh), complex surfaces.
How mappers estimate normals (and what they mean).
