Identifying damage on cars through the integrated use of TLS/SfM with thermographic images

The laser scanner is a detection technique essential for the 3D modeling of objects and it is well known its capability to acquire large amounts of data relatively in short times with a high degree of precision. In recent years also it is becoming more common some software-based algorithms "Structure from Motion" (SfM) which allow the graphic rendering of 3D models from images obtained by ordinary digital cameras. The integration of the 3D model with images obtained with infrared cameras can provide an overview not only on the state of conservation, but also provide, in addition to the dimensional characterization, also abnormality information, dimensional and form, invisible to human eyes and to other techniques. In particular, this application with the integrated use of terrestrial laser scanning instrumentation and advanced infrared camera can test a possible use for cars, after packaging and transport, in order to detect any damage caused by transport. We also will conduct the first tests on a possible use of the SfM to replace laser scanner
