The present invention relates to the field of coordinate measurements in the three-dimensional (3D) space to be taken on large objects (ranging from one meter to a few tens of meters in size) by using photogrammetric techniques. In particular, the invention relates to a feeler device for photogrammetric measurements, which can provide, with a high degree of accuracy, the three-dimensional coordinates of points touched by the feeler on the surface of an object being measured, by using as a reference a photogrammetric system consisting of high-resolution digital cameras with high depth of field. The invention further concerns a marker for such a feeler device and a measurement system for taking photogrammetric measurements, which allows obtaining accurate measurements on the object to be analyzed.

Abstract

The present invention relates to the field of coordinate measurements in the three-dimensional (3D) space to be taken on large objects (ranging from one meter to a few tens of meters in size) by using photogrammetric techniques. In particular, the invention relates to a feeler device for photogrammetric measurements, which can provide, with a high degree of accuracy, the three-dimensional coordinates of points touched by the feeler on the surface of an object being measured, by using as a reference a photogrammetric system consisting of high-resolution digital cameras with high depth of field. The invention further concerns a marker for such a feeler device and a measurement system for taking photogrammetric measurements, which allows obtaining accurate measurements on the object to be analyzed.
