The invention provides a device and a method for calibrating an inertial measurement unit of a micro electro mechanical system, the device comprises a rotary table structure and a data acquisition module, the rotary table structure comprises a driving module and a panel connected with the driving module through a driving shaft, the axial direction of the driving shaft is parallel to the ground and is vertical to the bearing surface of the panel, and the data acquisition module is connected with the rotary table structure. The bearing surface of the panel is used for arranging a to-be-calibrated inertial measurement unit; the driving module is used for driving the panel to rotate through the driving shaft so as to drive the to-be-calibrated inertial measurement unit arranged on the bearing surface to rotate; the data acquisition module is used for being connected with an output end of a to-be-calibrated inertial measurement unit so as to obtain an output value of the to-be-calibrated inertial measurement unit
