Recently, a method has been proposed by the authors for the measurement and evaluation with pychometric function using Probit method. The standard sample for the experiment of measuring the performance of panel was designed by means of paired comparison and constant stimuli. In order to evaluate the visual sensory properties of panel in the practical inspection task, the psychophysical experiment was performed to obtain the psychometric curves to evaluate the detection probability of target object. Three kinds of attributes such as size, aspect ratio, and degree of gray scale for the inspection image of FRP panel was prepared in experiment. Moreover, we propose an efficient method using Staircase method for the experiment and evaluation. The detection probability of Staircase method is compared with that of Probit method. The efficeince and accuracy in quality management are also discussed. In conclusion, our method can estimate the parameter of pychometric function efficiently.
