Moreover, it lays an important foreground to be applied in engineering for numeric control grinding.
The change of the grinding condition will cause the change of grinding forces and different elastic deformation of the grinding system, thus influencing the material removal rate.

For example: the depth is not continuous, the direction of surface is not continuous, the properties of material change and the lighting changes in the scene illumination, etc.
Therefore, the changes of material properties must be reflected in GPR (Ground Penetrating Radar) imaging [1], which is the basis for appling edge detection technology to GPR data processing.
Copying the processed imaging data back from device to host The key of implementing parallel Prewitt algorithm is how to construct processing grid and parallel kernel program [4].

Introduction Transportation infrastructure beam is comprised of five major transportation modes depending on the material engineering facilities such as railways, highways, waterways, aviation and pipeline.
Construction of the QingXin railway will shorten the time between Qinghai and Xinjiang, promote dual material, passenger and information flow and is beneficial to both the comprehensive utilization of tourism resources and coordinated development.
