A three-dimensional measurement method and device are intended for fast and accurate measurement of large objects such as vehicles. The method includes the steps of determining approximate measurement positions of a shape measurement sensor; positioning the sensor at successive approximate measurement positions to read off the shape of surface portions of the object represented by points on the object whose co-ordinates are expressed in a system of axes fixed relative to the sensor; identifying accurate positions of the sensor at the approximate measurement positions relative to a predetermined fixed system of axes; and converting the co-ordinates of the points of the surface portions expressed in the system of axes fixed relative to the sensor into co-ordinates expressed in the fixed system of axes on the basis of the identified accurate positions of the sensor.

Three-dimensional measurement of large objects

A motor vehicle side panel which includes at least two uprights and a lower member of the substructure of the vehicle which form a door frame, and at least one door mounted upon the door frame which includes a solid lower part formed of an outer panel and an inner panel defining a housing for a drop glass therebetween. The inner panel is substantially planar and includes an inner side facing the door frame when the door is closed, with the inner panel including an outer side which faces the outer panel. Steel sections are welded on the inner side of the inner panel and project toward the door frame, with the steel sections extending at least along the portions of the inner panel which face the upright members and the lower member of the door frame. The upright members and the lower member of the door frame are provided with parts which project outwardly toward the inner side of the inner panel, with the parts of the door frame extending adjacent and along the steel sections of the door such that an interlocking connection is provided between the periphery of the inner panel of the door frame when the door is in the closed position.
