Describe the bug

Image

IIRC there was a sliver of the top white strip next to the top right tag corner, but I don't fully remember.

To Reproduce
Steps to reproduce the behavior:

  1. Umich detector, 1280x720 (resolution probably doesn't matter)
  2. Position the tag as seen here
  3. See the detection with the tag corner clearly wrong.

Platform:

  • Hardware Platform (ex. Raspberry Pi 4, Windows x64): Orange Pi 5
  • Network Configuration (Connection between the Radio and any devices in between, such as a Network Switch): Direct from Orange Pi 5 to Radio AUX1, static IP 10.69.95.13
  • PhotonVision Version: 2025.1.1
  • Browser (with Version) (Chrome, Edge, Firefox, etc.): Firefox, version unknown
  • Camera(s) Used: Arducam OV9281

Will update with more pictures if I remember/have time. Currently hacked around this by filtering out estimates with tag corners less than 15 pixels from the border.
