Abstract
A visual navigation inspection and obstacle avoidance method for a line inspection robot is provided. The line inspection robot is provided with a motion control system, a visual navigation system and an inspection visual system; and the method comprises the following steps: (1) according to an inspection image, the inspection visual system determining and identifying the type of a tower for inspection; (2) the visual navigation system shooting a visual navigation image in real time to obtain the type of a target object; (3) coarse positioning; (4) accurate positioning; and (5) according to the type of the tower and the type of the target object, the visual navigation system sending a corresponding obstacle crossing strategy to the motion control system, such that the inspection robot completes obstacle crossing. The inspection and obstacle avoidance method is real-time and efficient.
