Challenge. Foreign inclusions such as metal fragments, stones and oversized chips are found when processing wood raw material. They damage equipment further down the processing chain and reduce the quality of the final product.
The task was to scan the flow of wood particles and detect oversized and foreign objects based on defined parameters.
Solution. We deployed a system comprising a high-speed video camera, directional lighting and dedicated software and algorithms. The camera captures the conveyor belt, the image is sent to a workstation for processing, and results reach the user with a 2-second response time.
Results- Foreign inclusions are detected according to the specified parameters with 97% probability.
- Calibration time for non-standard chips or other materials meets the technical specification at no more than 2 seconds.
