Wooden Window Frames Quality Inspection with AI: Case Study

Wooden Window Frames Quality Inspection with AI: Case Study

A leading European manufacturer of wooden window frames embarked on a mission to elevate the quality and integrity of their products.

Their vision was to implement a comprehensive visual surface inspection system that could thoroughly examine wooden window frames.

To achieve this, they partnered with EasyODM, a leading provider of machine vision quality inspection software, to meet their demanding quality control requirements

Challenges

  1. Employees spend a significant amount of time locating defects and making necessary repairs. This impacts overall production time, efficiency, and output.
  2. Defects often go unnoticed by employees and become apparent only in later production stages, such as after painting or varnishing. This results in additional work and costs to rectify defects or even necessitates discarding the item.
  3. Wooden window frames in production are prone to various visual defects, including but not limited to rough surfaces, pressed marks, damaged surfaces and rough surfaces, posing a significant quality control challenge.
