The work aims to propose a set of spatial coordinate calculation methods based on vision cameras to solve the problem of position and angle errors generated by the robots during the dynamic for-mation of multiple autonomous mobile robots. Firstly, a set of camera ranging and positioning sys-tem is built to introduce the composition and corresponding functions of each part in the system. Secondly, a three-dimensional space coordinate system is constructed, and the measurement pro- cess and calculation formula of key data in the coordinate system are introduced in detail. Finally, a formation system with multiple autonomous mobile robots is built to test and verify the above cal-culation method. The experimental results show that the calculation results of the robot coordi-nates meet the design expectations, and the entire formation process is well realized. It may be concluded that the dynamic formation technology of multiple autonomous mobile robots satisfies the requirements on engineering applications.
