TY - JOUR A1 - Hasche, Eberhard A1 - Karaschewski, Oliver A1 - Creutzburg, Reiner T1 - iPhone12 imagery in scene-referred computer graphics pipelines JF - Electronic Imaging N2 - With the release of the Apple iPhone 12 Pro Max in 2020, various features were integrated that make it attractive as a recording device for scene-related computer graphics pipelines. The captured Apple RAW images have a much higher dynamic range than the standard 8-bit images. Since a scene-based workflow naturally has an extended dynamic range (HDR), the Apple RAW recordings can be well integrated. To correctly integrate the iPhone 12 pro Apple RAW data into a scene-related workflow, two command-line software solutions, among others, are dcraw and rawtoaces. In this paper, we concentrate on dcraw. dcraw offers the possibility to export RAW images directly to ACES2065-1. Different images recorded under different lighting conditions are examined to determine which options for the dcraw development produce the best results. Images from five different lighting situations like D65, D60, D55, D50, and 2980K, are examined. The DNG files are developed using different methods within dcraw. The values of the recorded ColorChecker24 patches are compared to reference values derived from BabelColor [1] and ACES [2].

For this purpose, applications of LiDAR systems were classified into the typical application areas "3D modeling", "smart city", "robotics", "smart automotive" and "consumer goods". The investigation has shown that neither "mechanical" LiDAR technologies, nor so-called solid-state LiDAR technologies, nor "hybrid" LiDAR technologies can be evaluated as optimal for the typical application areas. In none of the application areas could all of the elaborated requirements be met. However, the "hybrid" LiDAR technologies such as sequential MEMS LiDAR technology and sequential flash LiDAR technology proved to be among the most suitable for most typical application areas. However, other technologies also tended to be suitable for individual typical application areas. Finally, it was found that several of the LiDAR technologies investigated are currently equally suitable for some typical application areas. To evaluate the suitability, concrete LiDAR systems - of different technologies and properties - were compared with the specific requirements of exemplary applications of an application area. The results of the investigation provide an orientation as to which LiDAR technology is promising for which application area.

T1 - Investigation of Practical Usefulness of Structure from Motion (SfM) Point Clouds Obtained from Different Consumer Cameras N2 - This paper deals with the usefulness and accuracy of point clouds obtained by different consumer cameras out of structure from motion (SfM) algorithms. It summarizes some research results of the practical usage of the SfM method in applications where highly accurate point clouds are required.

T1 - The 300th anniversary of Immanuel Kant: opportunities and challenges of the mega-event with ethically oriented XR and VFX T2 - SPIE Defense + Commercial Sensing, 2024, National Harbor, Maryland, United States N2 - The 300th birthday of the world-famous German philosopher Immanuel Kant (1724-1804) in 2024 offers an extraordinary opportunity to explore integrating advanced technologies into cultural mega-events. This paper examines the opportunities and challenges of using various technologies, such as Extended Reality (XR) and Visual Effects (VFX), to bring this essential European intellectual to a broader audience. These technologies, including technological advances based on real-time rendering in conjunction with LED volumes and high-quality 3D assets, offer immersive and interactive event experiences. However, the use of these technologies presents specific challenges, such as processing limitations and the need to create specialized content, including the development of 3D models relevant to the life and philosophy of Immanuel Kant. This article provides an overview of the current state of such opportunities and challenges and examines their application in the context of this cultural mega-event. The aim is to create a compelling event experience, e.g., as part of a museum visit, while simultaneously using technology in a meaningful educational way. It is essential not to overload historical and intellectual personalities such as Immanuel Kant with technological possibilities in the sense of an ethical responsibility. At the same time, the creation and communication of knowledge require explanation in a museum context or another explanatory framework.
