The invention discloses a braiding method and a braiding device. The method comprises the following steps: acquiring parameters of a braided fabric, wherein the parameters comprise a prototype parameter, a prototype extended parameter, a weave structure, a braiding density and a pattern; making the braiding diagram of the braided fabric according to all the parameters, wherein the braiding diagram comprises the prototype extended graph, a braiding scheme and a technologic list; and braiding the braided fabric according to the braiding diagram. The parameters of the braided fabric acquired, the braiding diagram of the braided fabric is made by the terminal according to all the parameters, and the braided fabric is braided by using the braiding diagram, so making of the braided fabric is completed without learning a complex cloth design, a pattern making technology, knitting software and pattern making software by an operator, thereby the making efficiency of the braided fabric is improved.
