In the PC cluster environment, parallel algorithms can significantly improve the efficiency of remote sensing image processing. The remote sensing dataset is the raster data stored by order of band, therefore, it is feasible to assign executable tasks to some computing nodes by band and complete the processing tasks together through communicating each other amount the computing nodes by MPI interface...
The paper puts forward a new high-precise noncontact measuring method combining photoelectricity and machinery in limited deep cavity to detect form and position of blind hole. System is composed of high-precise drive mechanism, endoscopic optical path, precision raster part, imaging acquisition and processing part. Endoscopic optical system is moved linearly through drive mechanism in limited deep...
