In this paper, a performance index, which is used to evaluate the operating uniformity of multi-cyclinder engine, is presented based on the fact that the fluctuation of gas pressure in the expansion stroke cyclinder leads to the fluctuation of instantaneous angular velocity. The value IP is propotional to the fluctuation of instantaneous angular acceleration. Fuzzy diagnostic index for misfire fault is introduced and investigated also in this paper.

In this algorithm, the strongest corner points is adaptively detected with Harris operator and (2n+1)×(2n+1) feature windows is selected for originally mutual gray correlative matching. Continental distance ratio invariant criterion is proposed, and consistency of motion vector is improved by eliminating error matching points with median filter. 9 pairs right points is preserved, 4 pairs composing 1 group, and 5 groups is random distributed to uncoil the motion vector equations. Last, stabilization precision is improved by averaging the 5 groups' solutions.

Sometimes it may seem perverse or obsessive, but more often it is a kind of inexplicable search. By going in search of ruins, I contemplate the half-withered and lonely soul deep inside me and enter into a dialogue for self-cure. But after seeing so many forgotten corners in the world, I become even more speechless and uncomprehending

有时不免觉得变态，或可说是某种偏执，但更多时候是一种莫名的追寻；藉由追寻废墟，观照自我内心深处那座半颓圮的孤独心灵，藉此展开自我疗伤式的对话，但在看尽世间如此多被人们遗忘的角落后，却更加无语与无解。
