As resolutions of different damage detection algorithms are quite not alike, the overall-information of a structure can t be obtained by single algorithm.

Comparing wi th the common mechanical-electric manner，these technologies have high er resolution and better anti-interfere ability.

This paper develops a method to obtain the high resolution multi perspective parallel mosaic from real sampled images, sets up a mathematic model for rendering high quality image from multi perspective image, and also analysises the upper bound of real image sampling rate.

Approximation of any quadric curve segments using Bézier polynomials or splines is presented For different types of quadric curves, the approximation is all six order accurate, and the adjacent approximation curve segments join with GC 1 continuity At last, we give the algorithm of parametric approximatio

The system has high accurate and excellent low-speed characteristics.

Discussed the mechanics quantity which berelated to length are measured by all kind of capacity sensors of working principle and analysis method Introduced the capacity sensorsare used in accurate measurement technology, then andlysed that different capacity sensors are in accurate measurement and decrese measurement error deviatio

Applied technique of automatic detection for warp and weft densities in fabrics:2.errors of detection and method of standardization;

On the foundation of the analysis and comparison of the error of the combination forecast and independent forecast,the paper has given the conditions of the former being least.

This research puts forward the concept of DEM terrain representation error (Et) first and then investigates the generation, major factors,measurement and simulation of Et.

An analysis was made about the surveying precision accuracy of different surveying graphes and points of intersection, drawing the conclusion that the surveying certainty was the best with the intersection angle 108°00′8″.

This article analyzes the influence of precision accuracy of thermometric instruments on the energy efficiency of an oil distribution station of a pipeline.
