Abstract: For reasons that it is difficult to develop a non-linear model for the evaluation of the fabric drap and the conventional evaluation method can not achieve the desired accuracy of it. The paper, in light of the features of fabric drape data, has proposed a Mercer kernel model for fabric drape assessment. It has proven by experiment and comparison that the precision of the fabric drape has increased by the new method and the assessment model based on Mercer kernel model is feasible. It also shows that different parameter values selected affect the assessment results.
