چکیده
Natural rubber is an important and strategic raw material, used in tires, gloves, insulating products, that mainly obtained by cutting the bark of trees. However, complex contour curve tree trunk hard to fit using a tapping machine. Thus, collection would be useful for development machines. In this study, acquisition system based on laser-ranging technology was proposed collect point cloud data trunks, B-spline fitting program compiled Matrix Laboratory (MATLAB) extract trunks’ curves. The composed power, controller, driver, laser range finder, transmission modules. An automatic extraction experiment curves trunks carried out verify feasibility accuracy system. results showed degree characteristic recognition reached 94.67%, which means successful are suitable irregular trunks. coefficient variation repeated 0.04%, indicates changes relative positions directions have little influence system, high stable. Therefore, it unnecessary adjust position device before collecting process, helped improve efficiency considerably. study meaningful practical production application agroforestry can not only precision process combining with machine but also provide technical support prediction wood volume ring-cutting equipment other fruit

متن کاملInterval B-Spline Curve Evaluation Bounding Point Cloud
We present an algorithm for bounding a piece of strip-shaped point cloud without self-intersections with an interval B-spline curve. Firstly we calculate the boundary points of the point cloud, and then bound it with an interval B-spline curve of which two pieces of boundary curves interpolate these boundary points. For the algorithm there are important applications in product shape verifying m...
متن کاملOptimal spline fitting to planar shape
Parametric spline models are used extensively in representing and coding planar curves. For many applications, it is desirable to be able to derive the spline representation from a set of sample points of the planar shape. The problem we address in this paper is to nd a cubic spline model to optimally approximate a given planar shape. We solve this problem by treating the control points which d...
