Application Of Detection Of Knots On Log And Computer Vision Reappear Theory

The paper is based on the project of "The Research of Mathematics and Computer Frequency Dynamic Simulation Theory on Knobs NOT Result". The research content is object to the image of log knobs by vidicon getting to detect the shape of log knobs according to the method of video disposal .The paper apply digital image processing technology to log knobs image to swell and detect borders,then distill the surface shape and characteristic parameter of knobs. The thesis depict the knobs three-dimensional models,build the mathematics models of log knobs and simulation two-dimensional image curve of the log knobs primary section which has been discerned,thereby achieve our researching aim to reappear the knobs image on computer.The system software is designed by Visual C++6.0 and model technology,base on Windows series operating system. It provides the good theory and application foundation for industrial popularization of log knob's automatic detection. The system apply itself to resolve the key problems in computer image processing and simulate reappear technology,taking full advantage of exiting equipment. The theory that discern the log knobs flaw by video method provide the essential theory premise and technology for the design and application of wood flaw detecting and discerning.
