General Description

On-Line Ore Sizing (OOS) is a non-contact vision inspection system of automatically determining the size distribution of ore on conveyor systems. Using active stereopsis OOS gives instantaneous feedback control as well as longer term analysis of product quality. Utilizing this automated visual quality inspection and vision inspection systems is possible at a reduced cost compared to manual methods.

The size of product on conveyor systems is a direct result of processes upstream and determines the requirements of processes downstream. The ability to size product automatically on-line can greatly increase the efficiency of these processes. Tightening the control of the process will improve the quality and ultimately the prices paid for the product.

How It Works

The OOS vision inspection system is made up from three primary components - laser light source, video camera and a computer. It uses Active Stereopsis - an image analysis technique which uses a light stripe. The light strip is projected on to and forms the profile of the ore. An image of the formed light stripe is captured by the video camera. Analysis of the light stripe by computer software quickly quantifies the 3D profile of the ore using triangulation techniques. This process is repeated continuously to build up a size distribution measure of the ore passing under the laser light.
