Abstract: More and more attention has been paid to the application and research of infrared image in recent years because of the uniqueness of infrared images. But its application has been restricted greatly due to the inherent defects, such as bad contrast, fuzzy edge and weak veins etc. And the relevant reports of the research are seldom. The preliminary research in the aspect was made. Two infrared pictures taken from two proper angles with Ti30 infrared instrument were processed through two methods: contrast self-adaptive histogram equalization and edge enhancement. At last, stereogram pair by the principle of two eyes fusion was observed. Experiment results show that the distinct space geometry distribution of every object can be obtained through observing the stereogram pair.
