英文摘要：

In order to solve the problem of localization of indoor mobile robot, the visual location method of indoor mobile robot based on beeline detectoion was put forward. In this algorithm, image edge was detected by Canny operator, and adaptive Hough transform was used to check the beelines in the image edge. After translational transformation and rotational transformation, by calculating the distance of the center of the visual field to the beelines, the real-time coordinate was obtained by tracking the beelines crossing of the center of the visual field through evidence reasoning. Experiments show that the algorithm with high positioning accuracy, is feasible and has a good real-time perform- ance and strong robustness, which gives a good solution to the problem of localization of indoor mobile robot.
