However, it is a difficult because the location is not easy of the line endpoint, and the line is easy broken. A line segments extracting algorithm is proposed based on SUSAN, and resolve the locat ion difficult problem of line endpoints. The experiment results show that the algo rithm is efficient and accuracy and the success detection rate is larger than 0% . The algorithm is important to ob ject recognition and 3D reconstruction.
