3D modeling is an important topic concerning visual inspection in automatic quality control. Through visual inspection, it is possible to determine whether a product fulfills the required specifications or whether it contains surface or volume imperfections. Although some processes such as color analysis can be achieved by 2D techniques, more challenging tasks such as volume inspection of large and complex objects/scenes may require the use of accurate 3D registration techniques. 3D simultaneous localization and mapping has become a very important research topic not only in the robotics field for solving problems such as robot navigation and mapping of 2D/3D scenarios but also in the computer vision community for the estimation of the camera pose and the registration of large-scale objects. Although their techniques differ slightly depending on the application, both communities tend to solve similar problems by means of different approaches. We present a survey of the techniques used by the robotics and computer vision communities, pointing out the pros and cons and potential applications of each approach. Furthermore, the most representative techniques have been programmed and tested, obtaining experimental results that provide an accurate comparison of the methods in the presence of noise and outliers.

important research topic not only in the computer vision community for quality control applications but also
in the robotics field for solving problems such as robot navigation and registration of large surfaces. Although

Nowadays, visual inspection is very important in the quality control for many industrial applications. However, the complexity of most 3D objects constrains the registration of range images; a complete surface is required to compare the acquired surface to the model. Range finders are very used to digitalize free form shape objects with large resolutions. Moreover, one single view is not enough to reconstruct the whole surface due to occlusions, shadows, etc. In these situations, the motion between reconstructed partial views are required to integrate all surfaces in a single model. However, the use of positioning systems is not always available or adequate due mainly to the size of the objects or the environmental conditions imposed by the precise mechanics which suffer from vibrations present in the industry. In order to solve this problem, a 3D hand sensor is developed to reconstruct 3D objects that let us to compare them with respect the original one.
In Computer vision there are a lot of applications that are based on the 3D vision. For example, object modeling for reverse engineering in manufacturing, map building, industrial inspection and so on. However, the surface acquired by most part of sensors only represents a part of the object. To solve this problem, several images of the same object are acquired in different positions. After that, all views are transformed to the same coordinate system. This process is known as Range Image Registration and it is the goal of this work.
This work surveys the most common registration methods. These kinds of methods are used to reconstruct 3D complete models of objects. Moreover, a classification of the registration methods is presented. This classification is based on the accuracy of the results. In this survey the principal methods are classified and commented. In order to compare them, experimental results are performed using synthetic and real data. The quality of some results indicates that the result of the registration can be used to compare a real object with the 3D models of them. It can be used in manufacturing process in order to inspect the quality of the produced objects.
