In the future, BeiDou Navigation Satellite System (BDS) will has a more widely application in various fields, and high accuracy and fast positioning will be increasingly demanded. Satellite selecting algorithm has a vital influence on positioning accuracy and speed. Therefore, optimal algorithm to select satellites is one of important steps; it will be benefit to improve positioning precision and...
As signal monitoring method of ship borne radar's rate gyros is too single to fulfill the users, the real-time detection system is designed and realized. This system can help users to judge the gyros' working order more intuitively and quickly through real-time data acquisition and graphic processing. At the same time, real-time index test and correlation detection between the correlated signals are...
Stereo vision has been used in many different applications such as robot, entertainment, and car electronics. Disparity-based distance estimation requires a large amount of computational resources because of high block-matching computations, especially on the high-resolution image pair. In this paper, we propose an algorithm for computing the distance between our own driving car and the front car...
When a micro cantilever with a nanoscale tip is manipulated on a substrate with atomic roughness, e.g., pushing an atomic-scale sample or etching the surface of the substrate to draw desired patterns, the periodical lateral frictional forces with stochastic fluctuations will induce stick-slip motion of the cantilever tip, which may greatly influence the precision of the nano manipulation. To reduce...
An image information restoration algorithm based on Long-Range correlation (LR-IIRA) can be efficiently applied in image interpretation, restoration, and error concealment. But this algorithm requires excessive computing time, which restricts its application on large-scale problems and real time problems. We propose a parallel LR-IIRA algorithm (PLR-IIRA) to parallelize the restoration processing...
