MHOI has implemented a carbon detector for line 1 at BSL in 2019 as a proof of concept about the feasibility of an automated system. This v1 implementation used an AI trained model and colour camera to distinguish between the two materials.

False Positive rate

Project History


This project required a significant amount of research and development to implement and improved on the v1 model. As part of the improvement it was decided to move away from using a convential camera and colour spectrum analysis and use a multispectrical camera. The Australian CSIRO were asked to conduct an extensive investigation into the light spectrum and intensity difference between the two materials. Through initial implementation of a new AI trained model on the spectrium data it was evident that the rate of false positives was still signnificantly high and a secondary source of truth would be needed.

To reduce the false positives of the belt detection a 3d laser line scanner was selected. This would be used to determine the material height.
