Image Dataset Size at 66% camera system uptime: a worked example

Suppose camera system uptime falls to 66%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate the number of usable training images that can be collected from a production inspection camera during a shift, based on trigger rate, parts inspected per shift, camera uptime, and image quality yield.

The inputs for this scenario

  • Camera trigger rate (images per part inspected): 2 images / part (held at the documented default)
  • Parts inspected per shift: 1,800 parts / shift (held at the documented default)
  • Camera system uptime: 66 % (the input this scenario stresses; the baseline uses 92)
  • Usable image yield (images suitable for training): 85 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross images per shift = trigger rate x parts per shift.
  • Usable training images per shift works out to 2,020 images at these inputs, and this is the headline figure for the scenario.
  • Gross images captured per shift works out to 3,600 images at these inputs.
  • Images lost to camera downtime works out to 1,224 images at these inputs.
  • Images rejected for quality works out to 356 images at these inputs.

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 28.26% below the baseline at 2,020 images.
  • It computes usable training images per shift by discounting gross captured images for camera uptime and usable image yield. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Usable training images per shift: 2,020 images (headline result)
  • Gross images captured per shift: 3,600 images
  • Images lost to camera downtime: 1,224 images
  • Images rejected for quality: 356 images
