The invention discloses a sewing method and system between a cloth paving machine and a cutting bed. The method comprises the steps of presetting the corresponding relation between target paving information and a target graph; receiving a matching instruction, and automatically matching the target paving information of a cloth needing to be laid currently with a target graph needing to be cut currently according to the corresponding relation after the matching instruction is received; automatically transmitting the target paving information to the cloth paving machine so that the cloth pavingmachine can lay the cloth needing to the laid currently according to the target paving information; automatically transmitting the target graph to the cutting bed so that the cutting bed can cut the laid cloth according to the target graph. Accordingly, the target paving information and the target graph can be automatically determined in the sewing process, and no on-site worker analysis determination is needed, so that the sewing efficiency is improved, and the error-tolerant rate is high.
