Camera and Laser Robust Integration in Engineering and Architecture Applications

Abstract

1.1 Motivation The 3D modelling of objects and complex scenes constitutes a field of multi-disciplinary research full of challenges and difficulties, ranging from the accuracy and reliability of the geometry, the radiometric quality of the results up to the portability and cost of the products, without forgetting the aim of automatization of the whole procedure. To this end, a wide variety of passive and active sensors are available of which the digital cameras and the scanner laser play the main role. Even though these two types of sensors can work in a separate fashion, it is when are merged together when the best results are attained. The following table (Table 1) gives an overview of the advantages and limitations of each technology.
