The invention provides a rotary type laser radar data correction method and system based on an inertial measurement unit. The rotary type laser radar data correction method and system based on the inertial measurement unit comprises the following steps that step 1, the inertial measurement unit and the rotary type laser radar are fixed to the same rigid body through rigid connection; step 2, the inertial measurement unit is connected with a hardware synchronous processing plate and an upper computer, and the rotary type laser radar is connected with the hardware synchronous processing plate and the upper computer; step 3, the hardware synchronous processing plate starts, the hardware synchronous processing plate sends PPS pulse level signals to the inertial measurement unit and the rotarytype laser radar simultaneously, after the hardware synchronous processing plate sends the PPS pulse level signals, the hardware synchronous processing plate sends time data based on GPRMC standard format to the rotary type l
