栅格法一般作为路径规划的环境建模技术来用，作为路径规划的方法它很难解决复杂环境信息的问题，一般需要与其他智能算法相结合。(Grid method is generally used as the environmental modeling technology of path planning. As a method of path planning, it is difficult to solve the problem of complex environmental information. Generally, it needs to be combined with other intelligent algorithms.)
