This article puts forward a rapid,untouched and all-side scanning method of plastic injection products in 3-D scanning system,by introducing the structural optical 3-D scanning method and feature flag point registration method according to the characteristics of 3-D information acquiring of plastic injection products.

A 3-D measuring data registration method for 3-D scanning system was developed based on feature points and iterative closet point (ICP) algorithm.

In this paper, the surface topography of resin bonded grinding wheel was measured by laser 3D scanning.

The problems in 3D scanning were dealt with.

This paper presents a 3D laser scanning rapid data acquisition system with the laser sensor and POS,which is designed for 3D scanning the both sides of railway.

PC controlled three-dimensional scanning set-up and application in data acquisition by PDTS;

The experimental result indicates that the design of three-dimensional scanning system for the design of power device can achieve good results for the anti-reach preliminary study purposes; the point cloud image conforms to the outlet of the silica gel of inta.

The technique shortens the production time of 3D deformation animation greatly by acquiring point clouds using 3D scanner and reconstructing those data into several independent NURBS surface models which.
