Application of image processing and different types of imaging devices for three-dimensional imaging of coal grains
Original language description
Precise particle size measurements are important in many aspects of engineering geology, e.g. in mineral processing and the study of methane hazard in coal mines. The volume of grains, estimated exclusively on the basis of dimensions of the grains differs tens of percent from the volume obtained from 3D digital measurements. This confirms that full three-dimensional automatic imaging can be used in the measurements of the particles. The paper discusses the technique of three-dimensional imaging performed with the use of three types of devices. Coal particles representing the 0.5?1.0 mm grain fraction were chosen as the research material. The measurements were performed by means of: X-ray computed tomography, confocal microscopy and optical profilometry. The last two techniques are less costly and more easily available than computed tomography. For the X-ray CT scanner, full three-dimensional imaging was performed. In the case of the other two techniques, only those parts of the particl
