The idea behind differential GPS is to remove as much errors as possible from the range measurements by establishing these errors at a reference site. In its most simple setup, a GPS receiver is located at a well surveyed position and its (pseudo) range measurements are compared with the actual calculated range from this receiver to the SV s. The differences between measured ranges and calculated ranges at the reference receiver are applied as corrections to the ranges measured by other receiver(s) close by.
This approach addresses two difficulties simultaneously: 1)
the range limitation of mobile robot sensors and 2) the difficulty of detecting buildings in
monocular aerial images. With the suggested method building outlines can be detected
faster than the mobile robot can explore the area by itself, giving the robot an ability to
“see” around corners. At the same time, the approach can compensate for the absence
of elevation data in segmentation of aerial images. Our experiments demonstrate that
ground-level semantic information (wall estimates) allows to focus the segmentation of
the aerial image to find buildings and produce a ground-level semantic map that covers
a larger area than can be built using the onboard sensors.
Range imaging offers an inexpensive and accurate means for
digitizing the shape of three-dimensional objects. Because most
objects self occlude, no single range image suffices to describe the
entire object. We present a method for combining a collection of
range images into a single polygonal mesh that completely describes
an object to the extent that it is visible from the outside.
This course is about "distributed algorithms".Distributed algorithms include a wide range of parallel algorithms,which can be classified by a variety of attributes.
anb 版的LBM程序 This code was written to show beginners in a simple and
c short way the relevant procedures of a lattice Boltzmann solver,
c pointing on how everything works "in principle". Nearly all
c procedures could be implemented other (and better) as it is done
c here, and even the algorithms used here could be changed to
c save memory and increase performance. But the code works correct,
c and we hope it will be good starting point for the first steps
c in the lattice Boltzmann field. Good luck !
