Automated digitization of radial charts

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