Syringe Vision: Volume Capture at Verification Checkpoints

The volume is measured off the syringe's own printed scale. The reader locates the graduation lattice, whose period is 0.2 mL by construction, and returns (stopper − top tick) ÷ period × 0.2 mL: continuous in the pixels, reported to 0.01 mL. No pixels-per-millilitre constant is carried in from another recording, and nothing in the expression is fitted to an expected answer.

A single frame is not a measurement. A hold certifies only where several frames of it agree within 0.6 mL of their median, and the published volume is the mean of the frames that agreed: so a stray frame moves nothing. Where the frames do not agree the volume is reported not evaluable rather than guessed: a preparation nobody could measure is a different finding from one measured out of tolerance. Reads are scored against the band the order carries, ±10% of the dose.

Every value the reader returned during the hold, to 0.01 mL. Green frames agreed with the median and set the certified volume; red frames disagreed and were dropped by the consensus rule, not by hand. The declined count is frames whose scale could not be read at all: the lattice was not periodic enough, or no stopper band stood out on the barrel: which carry no volume and are never interpolated over.

EARLIER WHOLE-MARK READ: CANDID FOOTAGE BASELINE, CENTER CAMERA

Kept for comparison. These are the reads from before the printed-scale reader: a model named the graduation the stopper sat on, so every answer landed on a printed mark and ±1 mL was the only tolerance that could honestly be drawn round it. The footage is candid: the technician never deliberately showed the syringe to the camera.

Candid footage: the technician never deliberately showed the syringe to the camera, yet 4 of 4 checkpoints were verified within ±1 mL. Each frame's volume is the median of 3 independent Gemini reads. Read Precision (±σ) is the spread of those independent reads at the verification frame: an honest measurement uncertainty. It is tight where the syringe is held clean and vertical (e.g. the diluent-filled read) and wider where it is tilted or finger-occluded during handling. The sub-millilitre (x.xx) resolution this section anticipated is what the printed-scale reader above now delivers: it measures against the barrel's own lattice instead of naming a mark, reports to 0.01 mL, and certifies on frame-to-frame consensus during the present-to-camera hold rather than on any single frame.
