This paper presents a method of stereoscopic panoramic video generation including techniques for panorama projection, stitching and calibration for various depth planes. The methods described can be used on video sequences captured by an arrangement of multiple pairs of cameras or multiple stereoscopic cameras mounted on a regular polygonal shaped camera rig. Algorithms can also be used in comb...

There are many types of display systems used in Augmented Reality (AR), each having specific application areas. Based on an extensive literature and technology review, this paper proposes the use of a transparent projection screen for users in a fixed position observing distant objects. The transparent projection screen is similar to head-up displays (HUDs) used in aircraft cockpits, since they...

Structural health assessments are essential for infrastructure. By using an autonomous panorama vision-based inspection system, the limitations of human cost and safety factors previously time-consuming tasks have been overcome. The main damage detection challenges to images (1) lack annotated defect image data, (2) in high-resolution images, (3) inherent distortion disturbance images. In this ...

The notable improvements on performance and low cost of digital cameras and GPS/IMU devices have caused MMSs (Mobile Mapping Systems) to be gradually becoming one of the most important devices for mapping highway and railway networks, generating and updating road navigation data and constructing urban 3D models over the last 20 years. Moreover, the demands for large scale visual street-level im...

The angular Instantaneous Field Of View (IFOV) of rotating mirror is constant in flying spot scanners and as a result the more area is viewed by mirror with going out of nadir condition and it will cause gradually compression of the effective pixel size at the extremities of scan line. This error is known as panoramic error that is so more sensible in sensors which have high angular Field Of Vi...

In this paper, we propose an automatic method of synthesizing panoramic radiographs from dental cone beam computed tomography (CBCT) data for directly observing the whole dentition without the superimposition of other structures. This method consists of three major steps. First, the dental arch curve is generated from the maximum intensity projection (MIP) of 3D CBCT data. Then, based on this c...

We discuss design techniques for catadioptric sensors that realize given projections. In general, these problems do not have solutions, but approximate solutions may often be found that are visually acceptable. There are several methods to approach this problem, but here we focus on what we call the “vector field approach”. An application is given where a true panoramic mirror is derived, i.e. ...

Today’s Virtual Reality applications require a high degree of immersion. This may be achieved by using a CAVE incorporating powerful 3D computer graphics workstations, panoramic multiple screen displays and projection walls, stereovision and interaction devices such as trackers and data gloves. This article describes Virtual Reality applications from the fields of scientific visualization in me...

Displaying panoramic and wide angle views on a flat 2D display surface is necessarily prone to distortions. Perspective projections are limited to fairly narrow view angles. Cylindrical and spherical projections can show full 360◦ panoramas, but at the cost of curving straight lines, interfering with the perception of salient shapes in the scene. In this paper, we introduce locally-adapted proj...

In general, a human has a pair of mental foramina, a single foramen on either side. However, when it is double or multiple, and smaller than the mental foramen, the additional foramen is termed accessory mental foramen (AMF) (Sisman et al., 2012). An AMF foramen is reported to be rare, with prevalence ranging from 1.4 to 10% (Balcioglu & Kocaelli, 2009). Bidimensional radiograph examinations, s...
