Autonomous operation planning system and method for excavator

The invention discloses an excavator autonomous operation planning system and method. The method comprises the steps that construction environment data of an excavator in the construction process are collected; the construction environment data is utilized to obtain a current excavation area; discretizing the excavation area, and obtaining a bucket tooth tip path plan in combination with the operation process of the excavator; re-planning the bucket tooth tip path plan to generate a bucket tooth tip path track meeting a motion condition; and the excavator is controlled and operated through the bucket tooth tip path track meeting the movement conditions. According to the method, a relation function between bucket tooth tip path planning and excavation volume is established, and a bucket tooth tip path track which conforms to excavation operation habits and can be full is calculated in combination with pose conditions of excavation points and self-limiting conditions of an excavator. 本发明公开了一种挖掘机自主作业规划系统及方法，所述方法
