Identity recognition method of system with multiple measurement cameras

Provided is an identity recognition method of a system with multiple measurement cameras. An upper computer sends a camera identity recognition code to each measurement camera three times in a row, each measurement camera confirms the received identity recognition code, if the received identity recognition codes are valid, parameters and the installation method of each camera are selected, and meanwhile each received identity recognition code is sent to the upper computer; if invalid, the received identity recognition codes are directly sent to the upper computer; if the upper computer judges that the identity confirmation of the measurement cameras is successful three times in a row, measurement data are started to be obtained from each measurement camera. According to the identity recognition method of the system with the multiple measurement cameras, the measurement cameras are the same, so that development and technical state control of products are facilitated. When the system is used, the measurement ca
