To provide a vehicle compartment deformation measuring method capable of facilitating initialization, dispensing with re-setting, making timely and efficient measurement, and having a high degree of freedom for measurement.
In this vehicle compartment deformation measuring method, a laser displacement meter is supported on a fixed point outside a vehicle compartment, the temperature and position of a displacement measuring point of the vehicle compartment at the initialization of the laser displacement meter are taken as the initialization temperature and initialization position, the temperature of the displacement measuring point of the vehicle compartment is measured, according to the obtained temperature, a deformation amount due to thermal expansion of the displacement measuring point relative to the initialization temperature is calculated, a displacement amount to the initialization position of the displacement measuring point is obtained by the laser displacement meter, and the measured displacement amount is calibrated by the deformation amount due to the thermal expansion of the previously calculated displacement measuring point to be taken as the vehicle compartment deformation amount of the displacement measuring point.
