Abstract: Compared with point features, high-level features, especially free-form linear features, contain abundant information, which are more beneficial to the consequent image interpretation and surface reconstruction, etc. But, the linear features that can be matched successfully with typical method are few. Concerning the weakness of typical matching methods, perceptual organization theory was introduced into the matching process, and an image matching method based on perceptual organization of linear features in stereoscopic images was proposed. According to the results of the experiment, this algorithm advances the success ratio of free-form linear features matching and increases the length of free-form linear features, which facilitates the subsequent manual objects extraction.
