Automated digitization of radial charts
Radial charts were commonly used in the industry to allow retrospective assessment of technological parameters. Today it is relevant to digitize the obtained data in order to simplify the automation of technological processes. Digitization of radial charts by means of standard methods is carried out with the help of human labor at significant time costs. The article proposes an automated method for digitizing radial charts using software, developed in the LabVIEW programming environment. The results of processing radial charts are displayed on the screen in numerical and graphical form, and can also be exported to a file (for example, to Notepad or MS Excel). The presented technique can be applied to images obtained on a color or black-and-white scanner, which minimizes geometric distortions, associated with the conversion of a paper document into electronic form, and ensures recognition quality of the clear plot line with an average relative error of up to 3 %. In case of ink fading or perspective photos of the diagram, the value of relative error can reach 8 %, as a result of which additional manual correction of the data will be required.

- B. Yu. Zuev
The paper presents the particular results of development of the method for modeling on equivalent materials in the recent years, concerning the evolution of the primary technical base of the laboratory – test benches, which allowed to supplement substantially the potentialities of physical modeling for its complex application jointly with the full-scale and mathematical methods in solving a number of actual tasks in mining geomechanics.
