Based on the deeply research on the operators for evaluating the form error of the new generation of GPS, Digital Metrology technique to evaluate the cylindricity error of shaft parts is introduced. On the basis of the analysis for geometric model of the cylindricity error, we build the linear programming models to evaluate the cylindricity error, and propose a new modified simplex method. Aimed at...
RS accuracy assessment for RS classification is a method by which reliability and variability of the result of RS classification are quantificationally described. The reliability analysis is a process of calculating classification accuracy at a probability level while the variability analysis is to estimate the dependability range of the classification accuracy. With a point sample the AEFD (Accuracy...
Grain production is of great importance to any country, especially to China where nearly two-thirds of the population lives in rural area. Hence, it is meaningful for local and central governments to get accurate information about main crops acreage in time. Remote Sensing Applications Centre (RSAC), subjugating to the Ministry of Agricultural of China, has been working on monitoring the main crops...
