【期刊论文】Detection of Gross Measurement Errors Using the Grey System Method
王中宇, Z. Wang, Y. Gao and P.Qin
Int J Adv Manuf Technol (2002) 19: 801-804,-0001,():
-1年11月30日
A novel emthod using grey system to detect the gross drrors involved in a measurement process is proposed. Although the gross drrors should be avoided completely, they can occur and on many occasions are nol apparent. The grey sysem theory is used to characterize the geometric aspects in the measurement. Theoretical analvsis of the principle of gross error detection is presented and a detection criterion is propoded. An experi-mental test shows that the proposed method compares favour-ably with statistical methods which are diffcult to implement when the distribution of the data is unknown and the sample sive is small.

Electromechanical Engineering College He'nan University of Science and Technology, Luoyang, 471003, China Based onthe computer aidedtesttechnique, a precision method form easuring the omprehensivetopographyofthe deep hole surface is developed The measuring principle and data processing method am described in detail A new built. up function has good Lfaearity and good contfauity. therefore it is easy to be subdivided by computer and the enor can be corrected conveniently. In order to get a high quality fringe signal, we apply a New correction technique which based on the least square method to correct the A/D values in real
