Terrestrial hyperspectral imaging – enabling real time ore face characterisation
Technology

The technology underpinning Plotlogic systems is founded on the principles of hyperspectral imaging.

This technology has evolved over the last few decades, driven by the military, space and remote sensing communities. These recent advancements, coupled with real-time computing processes, presents a significant opportunity for real-time ore face characterisation.

How it works

technology-how-it-works
A. The illumination source

Light, usually from the sun, provides a broad spectrum of known light at wavelengths across the visible, near infrared and shortwave infrared spectrum.

B. The target of interest

The ore face target, absorbs, reflects and scatters the light, based on the target materials composition.

C-E. Hyperspectral and other support sensors

Hyperspectral sensors then collect and process the light that is received from the face and convert it to digital signals. This sensor information can also be captured in parallel to other sensor information, such as lidar survey data.

F. Field and cloud based computational equipment

Computers can then apply algorithms to convert the data into useful information to gain valuable ore characteristic knowledge.

Plotlogic’s hyperspectral equipment – among best in Australia

While airborne hyperspectral imaging has been around for a number of decades, driven by the military and agricultural sectors, Terrestrial hyperspectral imaging is emerging technology.

Research grade field equipment

For research and development, Plotlogic’s philosophy is to utilise the highest quality research equipment available for hyperspectral imaging equipment from all over the world, including Europe and North America. Our research grade equipment is the envy of research institutions across Australia, and for that matter the globe. This research and development equipment provides us with the most accurate and precise equipment available, providing high resolution, both spatially, and spectrally, as well as centremetre level GPS precision.

This means that you can be confident that a Plotlogic OreSense® LV system is backed by the latest and most sophisticated research and scientific equipment.

How does Hyperspectral imaging work?

How does Hyperspectral imaging work?

When a material is illuminated by light, the amount of light absorbed, reflected, and scattered will vary according to the molecular structure of the material.

The interaction of light with matter is unique to each material on earth.

A hyperspectral imaging system captures the reflected component of the light that has interacted with the target, and then splits this light up into its’ component parts, which is then read by a sensor and converted to a digital signal

How can hyperspectral imaging technology be applied to mine sites?

Plotlogic’s hyperspectral cameras cover the spectral ranges from the visible to near-infrared (VNIR) to the short-wave infrared (SWIR) bands of the light spectrum. Recent progress has been made in relation to enhancing ore characterisation using complex data processing algorithms, based on machine learning techniques. Plotlogic is now optimising these real-time hyperspectral data processing algorithms for mining operations, with the first commercial product offering being OreSense® LV.

Development is also underway at Plotlogic for aerial scanning of mine sites, as well as a system that can be mounted above a conveyor belt, or on stockpiles to ascertain accurate characterisation of mineral or other content.

In addition to these products, Plotlogic is also actively researching the integration of the underlying OreSense® LV technology for fitment to earth-moving equipment, enabling scanning of a defined field of view of the target ore face while the mining equipment is excavating material. This new approach can be applied to real-time decision support, with the ultimate vision being to integrate this technology into autonomous mining systems.
