A correction method for a gyro sensor which measures angular velocity of a vehicle about an axis in a vertical direction includes a generation process of performing a process on a difference between a measured azimuth obtained by performing a process on an sensor output, which is an output from the gyro sensor, and a vehicle azimuth estimated by using markers arranged along a traveling road of the vehicle to obtain correction information and a correction process of correcting the measured azimuth obtained by performing the process on the sensor output, which is the output from the gyro sensor, by using the correction information.
