| Abstract: | A new method of using laser detection technology to reconstruct the shapes of log cross sections and calculate the size of the cross sections is introduced.A model of the measuring system is established using the principle based on enveloping theory and the detected data is collected by a wireless data collection system,then the data obtained from the collection is used to reconstruct the log shapes in the computer and carry out the determination of the coordinate of a point on the envelope curve as well as... |
