Visualisation continues to change rapidly in mining , driven by technological advancement in hyperspectral imagery and 3D

hese are exciting times for visualisation in mining , with the convergence of new technologies such as hyperspectral imaging and 3D remote sensor technology broadening the possibilities .
Miners can receive the “ extra dimension of wavelength ” for conventional images in hyperspectral imagery , providing a much richer data set .
Rather than expressing an image using red , green , and blue values at each pixel location , as is traditional , hyperspectral cameras instead record a complete spectrum at each point to create a 3D data set , sometimes referred to as a hyperspectral data cube .
The additional spectral dimension facilitates supervised learning algorithms that can characterise visually indistinguishable objects – capabilities that are highly desirable across multiple application sectors .
Combining hyperspectral imaging with sensors capable of detecting light beyond 1000nm enables even more information to be obtained , further enhancing the ability to distinguish different materials . bett
