Visual Control

HMS Module

The HMS is the most powerful vision based daily precision control system for watch hand movement on the market.

Powerful, Intuitive and Reliable

H2i has developed the most powerful vision based daily precision control system on the market. The HMS detects the angular position of the hands of a watch head, thanks to the contrasted and reflection-free images of its lighting system.

Specifications
  • Automatic watch centering
  • Automated hands detection
  • New watch model learning
  • State measurement in seconds
  • Daily precision calculated in s/d
  • Measurement duration from 15s to 60s.
  • Local or network database integration
  • Global precision < 0.2s (second hand > 10mm)
  • Vision field: 55 x 55mm
  • Dimensions: 250 x 370 x 330mm
  • Weight: 18 Kg
Options
  • Custom detection algorithms.
  • Accurate timebase (PCIe card, GPS, NTP)

How it Works

Two pictures of the watch are taken within a few hours (typically 24h). The computed time given by the angular position of the hands is compared to the precise time elapsed between the two pictures. The result is displayed in seconds or extrapolated in seconds per day.

Quickly Add New Watch Models

The learning phase of a new watch model is a simple and fast step since it takes only a few minutes: pick the center of the hands, draw their contours and let the algorithms take care of the rest (while you can go on with your work!).
