Multispectral vision based efficient weeding robot

The invention discloses a multispectral vision based efficient weeding robot comprising a travelling car, a transverse connecting device, a weeding cutting device and a master control system, wherein the transverse connecting device, the weeding cutting device and the master control system are arranged on the travelling car and are connected with each other. The multispectral vision based efficient weeding robot is capable of rapidly and effectively recognizing farmland weeds, strong in real-time property and suitable for actual field work; the weed clearing works inside and outside a row are simultaneously finished through the combination of a simple cutting structure and a pesticide spraying way, not only is the load of the travelling car reduced, but also the weeds can be thoroughly cleared, the weeding efficiency is high, and the problem for clearing the weeds inside and outside the row is effectively solved; and due to the adoption of a derusting device, the work efficiency of a cutting tool is increased
