“…Recently, with the advances in both the photogrammetry and immersive environments, the former becomes more widely considered as a feasible way of generating high-quality content for VR. Simultaneously, as remarked in 1998 by Chapman et al [52], VR opens up a range of new opportunities for application of digital photogrammetric technologies, not only for measurements purposes. Therefore, in this review, we report both on research that emphasizes enriching user-experience and facilitating the use of the VR immersive environment by the application of photogrammetric models, and on the usage of VR to aid extracting relevant data from the digital photogrammetric models, for practical, domain-related purposes.…”

Photogrammetry is a science dealing with obtaining reliable information about physical objects using their imagery description. Recent advancements in the development of Virtual Reality (VR) can help to unlock the full potential offered by the digital 3D-reality models generated using the state-of-art photogrammetric technologies. These models are becoming a viable alternative for providing high-quality content for such immersive environment. Simultaneously, their analyses in VR could bring added-value to professionals working in various engineering and non-engineering settings and help in extracting useful information about physical objects. However, there is little research published to date on feasible interaction methods in the VR-based systems augmented with the 3D photogrammetric models, especially concerning gestural input interfaces. Consequently, this paper presents the PhotoTwinVR -an immersive, gesture-controlled system for manipulation and inspection of 3D photogrammetric models of physical objects in VR.Our system allows the user to perform basic engineering operations on the model subjected to the off-line inspection process. An observational study with a group of three domain-expert participants was completed to verify its feasibility. The system was populated with a 3D photogrammetric model of an existing pipe-rack generated using a commercial software package. The participants were asked to carry out a survey measurement of the object using the measurement toolbox offered by PhotoTwinVR. The study revealed a potential of such immersive tool to be applied in practical real-words cases of off-line inspections of pipelines.

Abstract-A computational camera uses a combination of optics and processing to produce images that cannot be captured with traditional cameras. In the last decade, computational imaging has emerged as a vibrant field of research. A wide variety of computational cameras has been demonstrated to encode more useful visual information in the captured images, as compared with conventional cameras. In this paper, we survey computational cameras from two perspectives. First, we present a taxonomy of computational camera designs according to the coding approaches, including object side coding, pupil plane coding, sensor side coding, illumination coding, camera arrays and clusters, and unconventional imaging systems. Second, we use the abstract notion of light field representation as a general tool to describe computational camera designs, where each camera can be formulated as a projection of a high-dimensional light field to a 2-D image sensor. We show how individual optical devices transform light fields and use these transforms to illustrate how different computational camera designs (collections of optical devices) capture and encode useful visual information.

Selecting the appropriate 3-D capture and modeling technologies to create the contents of a virtual environment (VE) remains a challenging task. One of the objectives of the environment-modeling project in our laboratory is to develop a design strategy for selecting the optimum sensor technology and its configuration to meet the requirements for virtual environment applications. This will be based on experimental evaluation of all performance aspects of several systems for creating virtual environments. The main problems include: practical sensor calibration, the registration of images particularly in large sites in the absence of GPS and control points, the complete and accurate coverage of all details, and maintaining realistic-look at real-time rate. This paper focuses on the evaluation of the performance of some approaches to virtual environment creation using specifically designed laboratory experimentation. By understanding the potentials and limitations of each method, we are able to select the optimum one for a given application.
