Horus Field · Spatial calibration
Building one pitch from many views.
BlueX studies how pitch evidence and camera geometry can align multiple match angles to one consistent football space.

Research question
How can several cameras describe the same football space without treating every view as a separate match?
Why this matters
Study the behavior that changes the work.
Zoom, perspective, camera movement, and partial sightlines change what each view appears to show. A shared match representation requires the visible pitch evidence to agree before observations from different angles can be compared.
Pitch evidence
Study which line, boundary, and landmark observations remain dependable when the camera moves or the field is partially hidden.
Cross-view agreement
Align synchronized views to a common football space so the same moment can be examined without changing its spatial meaning.
Uncertainty by design
Keep ambiguous geometry visible as a review state instead of forcing every camera frame into a confident result.
Validation principles
Evidence before a claim.
A consistent pitch frame lets later research reason about movement, spacing, and match state without making each camera angle its own coordinate system.
Review long match sequences with camera motion, zoom, occlusion, and incomplete line visibility rather than only clean still frames.
Compare agreement across synchronized views and preserve disagreements for human review.
Verify that downstream player and ball observations remain attached to the same match space after view changes.
Reading standard
Evidence stays attached.
Spatial outputs remain linked to the source frame and view that support them.
Low-evidence calibration stays unresolved until a reviewer or stronger observation can establish it.
Shared coordinates are treated as evidence infrastructure, not as a tactical conclusion on their own.
