Point data reduction technique in reverse engineering;

In order to increase calculation speed of reconstruction, reduce memory space, and, at the same time, emphasize modelling characteristics, a method of data reduction with triangular folding was proposed by using triangular meshes model and ordering function on the basis of analysis of data reduction method available.

In order to reduce the data point-cloud of auto panel die’s surface acquired by non-contact 3D measurement, a kind of data reduction method is presented based on the average point-to-point distance principle.

Research on data simplification for point cloud in surface reconstruction

Key of the data simplification technology is while at the same time of simplifying the data to reserve the original characteristics of point cloud data to the largest extent.

This paper discusses several problems in non-contacted three-dimensional scanning measurement data processing,such as noise points deleting,distortion point searching,data simplification and smooth processing,point cloud data registration and integration.

Aiming at the application of PDM in design domain,an oriented dynamical data PDM system is researched and developed.

On preprocessing method of INS dynamic data;

A Strategy and Implementation of Embedded Browser Dynamic Data Processing Based On Iframe;

Line graph and semi-logarithmic line graph are both popularly applied to describe dynamic data intuitively.
