A method for measuring a damaged vehicle, in which - a measuring device is calibrated and an inclination of the vehicle is measured in longitudinal and lateral directions, - the measured inclination of the vehicle is used as a datum plane, - after calibration first measuring head of the measuring device is directed and set on a measuring point, the start point, chosen from an undamaged area of the vehicle, - second measuring head is directed and set on a second measuring point, the end point, chosen from an area desired to measure, - with a measuring sensor of the measuring device are measured the distance of measuring points, which is the length between the start point and the end point, of the vehicle and the measured data are compared to registered reference values of the measuring points, and with an inclination sensor of the measuring device is measured inclination of the measuring device, - with the measurement device are simultaneously measured the distance of the measuring points and the inclination of the damaged vehicle, - with an inclination sensor is measured the inclinations in the directions of two axes at the minimum by measuring the inclinations of at least two axes in the length direction of the profile of the measurement device, whereby the first axis shows the inclination used for calculating the height in the vertical direction and the second axis shows the inclination used for calculating height in the lateral direction in relation to the profile, - measuring the damaged vehicle in different points, - measured dimensions are read to a central processing unit, and - height difference of the measurement points is calculated from the values of the distance between the measuring points and the inclination. - a measuring device is calibrated and an inclination of the vehicle is measured in longitudinal and lateral directions, - the measured inclination of the vehicle is used as a datum plane, - after calibration first measuring head of the measuring device is directed and set on a measuring point, the start point, chosen from an undamaged area of the vehicle, - second measuring head is directed and set on a second measuring point, the end point, chosen from an area desired to measure, - with a measuring sensor of the measuring device are measured the distance of measuring points, which is the length between the start point and the end point, of the vehicle and the measured data are compared to registered reference values of the measuring points, and with an inclination sensor of the measuring device is measured inclination of the measuring device, - with the measurement device are simultaneously measured the distance of the measuring points and the inclination of the damaged vehicle, - with an inclination sensor is measured the inclinations in the directions of two axes at the minimum by measuring the inclinations of at least two axes in the length direction of the profile of the measurement device, whereby the first axis shows the inclination used for calculating the height in the vertical direction and the second axis shows the inclination used for calculating height in the lateral direction in relation to the profile, - measuring the damaged vehicle in different points, - measured dimensions are read to a central processing unit, and - height difference of the measurement points is calculated from the values of the distance between the measuring points and the inclination.
