Important results from the project
The aim with this project was to verify that it is possible to build a 3rd party system to analyze and evaluate the adhesive application quality in glued finger joints in construction wood (CW & CLT). In collaboration with Swedish sawmills, we have achieved the following objectives: - Verified that it is possible to detect and measure applied adhesive during finger jointing of wood using video analysis technology. - Verified that it is possible to analyze the quality of the workpieces with regard to cracks, twigs and defects in milling. - Taken the technology to production level.
Expected long term effects
This project has enabled us to independently produce and package this as a standardized project solution. We expect to be able to deliver a number of systems for quality monitoring of the production of structural timber in the coming years.
Approach and implementation
The project was divided the project in three steps: 1. Proof-of-Concept - A simple test where we collected a number of images, in different production lines. These were analyzed with image analysis tools to extract as much information as possible. 2. Analysis - development of robust analysis algorithms that provide consistent results across many iterations, as well as a basic user interface. 3. Pilot - Carrying out a test installation in two different environments. The setup has worked well but we had underestimated the mechanical difficulties in the industrial environment. .
