摘要：

Time-to-contact (TTC) estimation problem between moving object and static observer was dealt with. A feature-line based estimation scheme was proposed. And a TTC estimation system based on feature-point tracking was presented. In addition, the feature-point selection method, moving objects extraction, and feature-point tracking scheme were given in detail. The experiments of TTC estimation for three sets of the TTC-labeled image sequences were done, and the results are satisfactory.
