“…Accurate calibration and time synchronization are significant issues in this area, and even incorrect depth perception can lead to serious consequences. Specifically, [19] presents an AR system for oral or maxillofacial surgery, providing 3D virtual presentations of osseous structures and soft tissues in the patient's body.…”

Augmented Reality (AR) is an emerging technology that provides a user experience of augmenting the real world with virtual objects, and allows the user to interact with the virtual objects in real time and space. An AR ecosystem brings content providers, users, AR application developers, AR device manufacturers, and researchers together, making the whole AR environment sustainable. As technology (e.g., sensor tracking, ad hoc routing, computer vision and mobile computing) for supporting AR applications is developing rapidly, content is emerging as a key issue to focus on. In this paper, the state of art in AR from the content generation perspective is reviewed, and three key steps are introduced, namely data collection, content fusion, and content display. Some AR systems and current trends are also briefly discussed.

“…1,2 However, a disadvantage of such systems is that the images obtained are two-dimensional, and therefore, necessitate constant comparisons between the surgical field and the displayed image, and consequently, frequent hand-eye transformations. 3 The two-dimensional information gathered is thus indirectly recognized and understood, resulting in a potentially large gap between the actual patient morphology and its interpretation through the imaging system. With 3D models too, smaller surface details might be smoothened away and information may be lost.…”

“…The algorithms and conditions required for 3D virtual representation of the surgical area have been defined by previous research, in which integral videographic (IV) images of only the mandibular component were included. 3 However, this is the first study in which dentomaxillofacial 3D computed tomography (CT) data (both maxillary and mandibular jaws along with teeth (crown and root apices)) generated by a 3D IV image display system were superimposed on a human volunteer. In addition, the study evaluated if real-time in situ AR allowed accurate display of the stereoscopic images of the maxilla, mandible and teeth, even when viewed from different angles.…”

To evaluate the feasibility and accuracy of a three-dimensional augmented reality system incorporating integral videography for imaging oral and maxillofacial regions, based on preoperative computed tomography data. Three-dimensional surface models of the jawbones, based on the computed tomography data, were used to create the integral videography images of a subject's maxillofacial area. The three-dimensional augmented reality system (integral videography display, computed tomography, a position tracker and a computer) was used to generate a three-dimensional overlay that was projected on the surgical site via a half-silvered mirror. Thereafter, a feasibility study was performed on a volunteer. The accuracy of this system was verified on a solid model while simulating bone resection. Positional registration was attained by identifying and tracking the patient/surgical instrument's position. Thus, integral videography images of jawbones, teeth and the surgical tool were superimposed in the correct position. Stereoscopic images viewed from various angles were accurately displayed. Change in the viewing angle did not negatively affect the surgeon's ability to simultaneously observe the three-dimensional images and the patient, without special glasses. The difference in three-dimensional position of each measuring point on the solid model and augmented reality navigation was almost negligible (<1 mm); this indicates that the system was highly accurate. This augmented reality system was highly accurate and effective for surgical navigation and for overlaying a three-dimensional computed tomography image on a patient's surgical area, enabling the surgeon to understand the positional relationship between the preoperative image and the actual surgical site, with the naked eye.

Maintenance in scientific facilities is a difficult issue, especially in large and hazardous facilities, due to the complexity of tasks and equipment. Augmented reality is a technology that has already shown great promise in the maintenance field. With the help of augmented reality applications, maintenance tasks can be carried out faster and more safely. The problem with current applications is that they are small-scale prototypes that do not easily scale to large facility maintenance applications. This paper presents a new hybrid approach that enables the creation of augmented reality maintenance applications for large and hazardous scientific facilities. In this paper, a new augmented reality marker and the algorithm for its recognition is proposed. The performance of the algorithm is verified in three test cases, showing promising results in two of them. Improvements in robustness in the third test case in which the camera is moving quickly or when light conditions are extreme are subject to further studies. The proposed new approach will be integrated into an existing augmented reality maintenance system.
