Image Dataset Size at 99% camera system uptime: a worked example

This scenario runs the image dataset size calculation on the strong side: 99% camera system uptime, with every other input held at its documented default. Use it when planning an AI inspection training data collection campaign and you need to know how many usable images will be captured per shift before committing the production schedule.

The inputs for this scenario

  • Camera trigger rate (images per part inspected): 2 images / part (unchanged)
  • Parts inspected per shift: 1,800 parts / shift (unchanged)
  • Camera system uptime: 99 % (raised for this scenario; the documented default is 92)
  • Usable image yield (images suitable for training): 85 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross images per shift = trigger rate x parts per shift) to the inputs above produces each figure below.
  • At this operating point the engine returns 3,029 images for usable training images per shift, the number this scenario is built around.
  • At this operating point the engine returns 3,600 images for gross images captured per shift.
  • At this operating point the engine returns 36 images for images lost to camera downtime.
  • At this operating point the engine returns 535 images for images rejected for quality.

How this compares with the baseline

  • Against the tool's baseline example, where camera system uptime sits at 92% and the headline result is 2,815 images, this scenario comes in 7.61% above the baseline at 3,029 images.
  • Use it when scoping a data-collection campaign for a new vision model or estimating how many shifts of capture you need before a retrain. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Usable training images per shift: 3,029 images (headline result)
  • Gross images captured per shift: 3,600 images
  • Images lost to camera downtime: 36 images
  • Images rejected for quality: 535 images
