Technical Field
[0001] The present invention relates to the field of identification technology, and in particular to a path identification device and method for an intelligent weeding robot. Background Art
[0002] The smart weeding robot is a robotic device that uses advanced technology and algorithms to automatically perform weeding operations.
[0003] The intelligent weeding robot needs to use a camera to identify the surrounding environment and identify the path during work. During the operation of the weeding robot, grass juice, cut fibers, grass leaves and dust on the grass leaves will be scattered into the air from the cross section. The cut fibers and dust will adhere to the mirror of the camera under the action of grass juice, thus hindering the robot's accurate identification. At the same time, water stains are likely to remain during manual cleaning, and dirt is likely to adhere to the cleaning objects, so the cleaning objects need to be cleaned regularly. For this reason, we propose a path recognition device and method for an intelligent weeding robot. Summary of the invention

Because the cut fibers and dust adhere to the mirror of the camera under the action of grass juice, the robot's accurate recognition is hindered. At the same time, water stains are likely to remain during manual cleaning, and dirt is likely to adhere to the cleaning objects, so the cleaning objects need to be cleaned regularly.

[0005] Further preferably, a camera is fixedly sleeved inside the mounting seat, a mirror is fixedly connected to one side of the camera, and one side of the mounting seat, one side of the camera and one side of the mirror are coplanar.
[0006] Further preferably, the plurality of fixing members are respectively fixedly connected to the four corners of one side of the mounting seat, the interior of the moving member is threadedly connected to the threaded rod via a thread, and the sliding rod penetrates one side of the interior of the moving member for sliding connection.
[0007] Further preferably, the other side of the sponge strip extends to a side on which the mounting seat, the camera and the mirror are coplanar, and the other side of the scraper strip extends to a side on which the mounting seat, the camera and the mirror are coplanar.
