Defect Count

Quantify the Number of Defects per Zone with Customizable Limits

Overview

This module counts the total number of defects within a specified inspection zone. It allows usersto define an acceptable defect threshold per zone. If the number of detected defects exceeds the limit, the part is flagged as NOK (not okay).

Why It Matters

Not all defects lead to rejection, but too many, even small ones, can compromise product quality. By counting defects per zone, this module helps ensure quality standards while avoiding unnecessary rejections. It’s especially effective when combined with other modules such as Defect Size Measurement.

Where It’s Used

  • Healthcare / Medical
  • Chemical Production
  • Food and Beverage
  • Biolabs
  • Automotive
  • Aerospace

Capabilities

  • Counts all detected defects in user-defined zones
  • Individual defect count limits for each zone
  • Integrates with Defect Size
  • Measurement for dual filtering (quantity + size)
  • Flags parts as NOK when count exceeds threshold
  • Supports multiple zones with different tolerance levels
  • Enables smarter and more flexible quality control decisions

Automatic Rejection Based on Defect Volume

Counting Defects Within Defined Tolerance Limits

Image 2 shows three defects, exceeding the limit and flagged as NOK. Image 4 shows two defects, within limit, marked as OK. The system compares counts to a configurable threshold in real time.

Example Use Case

A medical device manufacturer allows up to 3 small defects in the lower part of a component but only 1 in the upper part. The module is configured to apply different count limits per zone. If either zone exceeds the defined count, the product is marked as NOK, even if each individual defect is small.
