[0002] At present, with the increasing demand for Chinese medicinal materials, efficient and accurate methods of digging Chinese medicinal materials have become extremely important. Among them, the digging work for angelica is still mainly done manually. When digging angelica, tools are needed to clean the soil near the rhizomes of angelica. In order to avoid accidental damage to the roots of angelica, each step needs to be carried out slowly during the digging.

[0003] Since the traditional method of digging Chinese medicinal materials often relies on manual operation, it is inefficient and easy to cause damage to Chinese medicinal materials. In addition, since the roots, stems and leaves of Angelica sinensis have different medicinal effects and certain commercial values, and the roots, stems and leaves of Angelica sinensis have different appearances due to different growth environments and characteristics, although manual digging can avoid causing excessive damage to the stems and leaves, it is difficult to provide a visual distribution of the roots, so the digging of the roots of Angelica sinensis is more laborious. Although the current method of digging angelica with mechanical equipment is not the mainstream digging method, it is efficient. However, it is difficult to avoid damage to the roots, stems and leaves of angelica during mechanical digging. Therefore, the digging of angelica plants due to different growth environments and characteristics requires an digging method targeted at maturity. Therefore, an automated excavation machinery trajectory planning and navigation method is needed to improve excavation efficiency and quality while reducing damage to Chinese medicinal materials. In view of this, we propose an automated trajectory planning and navigation system for Chinese medicinal materials excavation machinery. Summary of the invention
