Measuring amount and quality of goods is a common logistics problem. For a client in the paper industry, we have developed an truck load measurement system that computes stock good volume and provides access to high-resolution data for quality (semi-automatic) inspection.
Trucks shortly stop under a gantry where the truck is scanned. The data gathered is instantly analysed by a software module that processes the input data and matches it against operator-provided truck information. After a few seconds, volume information is complete and can be used to hand out receipts, complete with a visualisation of the scanned material.
The sensors consist of an array of stereo cameras that cover the complete truck. This way a complete scene can be captured in one instant resulting in high precision results.
The 3d data can be used in other modules, like material classification (via tone and texture analysis for quality control) as well as object classification.
