## Description
|
|
|
|
<!-- SECTION:DESCRIPTION:BEGIN -->
|
|
Write cv-pipeline.js (MediaPipe ObjectDetector from CDN, EfficientDet Lite 0 float16, VIDEO mode, detection overlay drawing) and pointer-mapper.js (FOV-based bbox→pan/tilt angle conversion with exponential smoothing).
|
|
<!-- SECTION:DESCRIPTION:END -->
|
|
|
|
## Acceptance Criteria
|
|
<!-- AC:BEGIN -->
|
|
- [ ] #1 Dynamic import from MediaPipe CDN with GPU delegate + CPU fallback
|
|
- [ ] #2 detectForVideo returns normalised bboxes with centerX/centerY
|
|
- [ ] #3 drawDetections: green for target, amber dashed for others, HiDPI aware
|
|
- [ ] #4 pixelToAngles: mirrored X axis, 80/60 FOV default
|
|
- [ ] #5 relativeTarget for fallback anchor offsets
|
|
- [ ] #6 Exponential smoothing factor 0.3
|
|
<!-- AC:END -->

|
## Final Summary
|
|
|
|
<!-- SECTION:FINAL_SUMMARY:BEGIN -->
|
|
cv-pipeline.js: MediaPipe Tasks Vision CDN, EfficientDet Lite 0, normalised detections, styled overlay. pointer-mapper.js: FOV mapping, EMA smoothing, relative fallback.
