近年來在計算與評估工業產品的範疇，學者提出了多種以人類察覺的能力為基的評估偵測機率的方法。在心理測量學方面，尺寸、平坦程度與灰階被用為機率單位法(Probit Method)的三項屬性值作為，推斷心理測量學曲線的分配參數。本研究，我們提出一種有效率的方法，以階梯(Staircase Method)為基，運用於實驗與評估的實務應用。以一實驗為例，測量調查對象或受試者在檢驗纖維強化塑膠產品所取得之不良品影像，對於三項屬性的感知刺激，並做階梯法的偵測機率與機率單位法比較。最後，將所提出方法之檢試其效率，並以心理測量函數的參數用於實務評估。

Recently, an evaluation method of detection probability has been proposed by the authors for the measurement and evaluation of the industrial products based on the human detectable ability. In the psychometric mesurement, distributed parameta of pychometric curve had been presumed using Probit method concerning the three kinds of atribute of size, flatness degree and grayscale. Moreover, in this thesis, we propose an efficient method for the experiment and evaluation by Staircase method for the practical uses, and the detection probability of Staircase method is compared with that of Probit method, taking an example of experiments in which the methods are applied to measure the perception stimulation of panels, or subjects, concerning the three atributes that are extracted from the defect images in the inspection of FRP (fiber reinforced plastics) poroduct. In conclusion, the proposed method will be overviewed its efficiency and proved for the practical estimation uses of the parameter of pychometric function.
