# Brief 1: Quad corner detection + perspective warp
|
|
|
|
## Goal
|
|
|
|
Replace axis-only Sobel box hunt with four-corner refinement and a
|
|
homography warp helper that produces rectified card JPEGs.
|
|
|
|
## Acceptance criteria
|
|
|
|
- [ ] `lib/scanner-card-warp.js` exports `orderQuadCorners`,
|
|
`computeHomography`, `warpCardCaptureFromVideo`
|
|
- [ ] `detectCardShapesFromFrame` returns `corners` in video space
|
|
- [ ] Tracker merge preserves `corners` on tracked cards
|
|
- [ ] Unit tests for warp math + corner refinement
