Отображение навигационной информации в виде проекции на лобовое стекло автомобиля или стекло мотошлема обеспечивает ее восприятие водителем без переключения внимания с дороги на приборную панель, тем самым повышая безопасность дорожного движения. Используемые в настоящее время технологии визуализации информации для навигационного оснащения автомобиля или мотоцикла достаточно дороги и мало распространены, поэтому создание простого и недорогого в разработке программного обеспечения с открытым кодом, повышающего эффективность обработки и отображения информации, представляется актуальным. Предложена архитектура построения подобной системы навигации с применением технологии подсказок водителю в виде объектов дополненной реальности и использованием открытых геоинформационных сервисов. Рассмотрены применяемые в технологии структуры и типы данных, а также возможный набор аппаратных средств визуализации навигационной информации. Алгоритмы визуализации динамических объектов дополненной реальности и обработки геоданных реализованы в программном коде на языке Python. Разработан интерактивный интерфейс, обладающий интегрированным эффектом от совмещения преимуществ навигационных систем и сервисов геоинформационных данных. Приведены результаты тестирования работы кода при визуализации направления движения по заданному маршруту в режиме реального времени Displaying navigation information in the form of a projection onto the windshield of a car or the glass of a motorcycle helmet ensures its perception by the driver without switching attention from the road to the dashboard, thereby increasing road safety. The currently used information visualization technologies for the navigation equipment of a car or motorcycle are quite expensive and not widely used, therefore, the creation of simple and inexpensive open-source software that increases the efficiency of information processing and display seems to be relevant. The article proposes an architecture for building such a navigation system using the technology of prompting the driver in the form of augmented reality objects and using open geoinformation services. We considered the structures and types of data used in technology, as well as a possible set of hardware for visualization of navigation information. We implemented algorithms for visualization of dynamic objects of augmented reality and processing of geodata in the program code in the Python language. We developed an interactive interface that has an integrated effect of combining the advantages of navigation systems and geoinformation data services. We give the results of testing the code when visualizing the direction of movement along a given route in real time

Abstract Introduction Endoscopic skull base approaches are broadly used in modern neurosurgery. The support of neuronavigation can help to effectively target the lesion avoiding complications. In children, endoscopic-assisted skull base surgery in combination with navigation systems becomes even more important because of the morphological variability and rare diseases affecting the sellar and parasellar regions. This paper aims to analyze our first experience on augmented reality navigation in endoscopic skull base surgery in a pediatric case series. Patients and methods A retrospective review identified seventeen endoscopic-assisted endonasal or transoral procedures performed in an interdisciplinary setting in a period between October 2011 and May 2020. In all the cases, the surgical target was a lesion in the sellar or parasellar region. Clinical conditions, MRI appearance, intraoperative conditions, postoperative MRI, possible complications, and outcomes were analyzed. Results The mean age of our patients was 14.5 ± 2.4 years. The diagnosis varied, but craniopharyngiomas (31.2%) were mostly represented. AR navigation was experienced to be very helpful for effectively targeting the lesion and defining the intraoperative extension of the pathology. In 65% of the oncologic cases, a radical removal was proven in postoperative MRI. The mean follow-up was 89 ± 79 months. There were no deaths in our series. No long-term complications were registered; two cerebrospinal fluid (CSF) fistulas and a secondary abscess required further surgery. Conclusion The implementation of augmented reality to endoscopic-assisted neuronavigated procedures within the skull base was feasible and did provide relevant information directly in the endoscopic field of view and was experienced to be useful in the pediatric cases, where anatomical variability and rarity of the pathologies make surgery more challenging.

FPGA and ASIC implementation of the algorithm for traffic monitoring in urban areas This paper describes the idea and the implementation of the image detection algorithm, that can be used in integrated sensor networks for environment and traffic monitoring in urban areas. The algorithm is dedicated to the extraction of moving vehicles from real-time camera images for the evaluation of traffic parameters, such as the number of vehicles, their direction of movement and their approximate speed. The authors, apart from the careful selection of particular steps of the algorithm towards hardware implementation, also proposed novel improvements, resulting in increasing the robustness and the efficiency. A single, stationary, monochrome camera is used, simple shadow and highlight elimination is performed. The occlusions are not taken into account, due to placing the camera at a location high above the road. The algorithm is designed and implemented in pipelined hardware, therefore high frame-rate efficiency has been achieved. The algorithm has been implemented and tested in FPGA and ASIC.

This article is devoted to the issues of visualization and information processing, in particular, improving the visualization of three-dimensional objects using augmented reality and virtual reality technologies. The globalization of virtual reality has led to the introduction of a new term "augmented reality"into scientific circulation. If the current technologies of user interfaces are focused mainly on the interaction of a person and a computer, then augmented reality with the help of computer technologies offers improving the interface of a person and the real world around them. Computer graphics are perceived by the system in the synthesized image in connection with the reproduction of monocular observation conditions, increasing the image volume, spatial arrangement of objects in a linear perspective, obstructing one object to another, changing the nature of shadows and tones in the image field. The experience of observation is of great importance for the perception of volume and space, so that the user "completes" the volume structure of the observed representation. Thus, the visualization offered by augmented reality in a real environment familiar to the user contributes to a better perception of three-dimensional object.

Automatic navigation in an unknown environment raises various challenges as many cues about orientation are difficult to perceive without the use of vision. Though assisted aids such as GPS devices help in route finding, still it fails to fulfill safety requirements. This paper proposes a framework that provides accurate guiding and information on the route traversal and the topography of the road ahead. The framework is composed of technologies such as Lumigrids, Drone, GPS, Mobile applications, Cloud storage which are used to map the road surface and generate proper navigation guidance to the end user. This is done in three stages; [1]. Off-line mapping of the road surface and storing this information in the cloud. 2. Wearable technology used for obtaining in real-time surface information and comparing it to the data on the cloud facilitating accurate and safer navigation 3. Updating the cloud information with information collected by the pedestrian 


Recently, accidents involving ground transportations are getting worse and more serious. Indonesian State Police (Korlantas POLRI) recorded the number of accidents in 2018 as many as 109,215 accidents. The number has incresed 4.69 percent compared to 2017 as many as 104,327 events. Road traffic accidents are caused by human error, the driver in this case. The driver's mistake is influenced by several factors, one of them is they cannot expect the road condition when they drive a vehicle at high speed. To solve this problem, drivers need information that can show road conditions. So, we present a new approach for detecting damaged roads by applying augmented reality technology. This research produces a road condition information system to help drivers get information about road conditions via smartphone. This system uses augmented reality technology with a markerless GPS Based Tracking method. The development of this system requires several stages such as collecting the data, data conversion, data classification, and views road condition. The researchers gathered the road condition data from the Public Work Department Semarang. This department itself undertakes a task to control the road condition in Semarang The trial of this system includes all drivers in Semarang city. Based on the results of the questionnaire responded to by 93 respondents, this test obtained an average value of 68%. So this system gets a pretty good response from the driver. Through this system, all drivers can avoid the damaged road condition which can cause traffic-congested and accident.

We report on an experiment on the distracting effects of in-car conversations through augmented-reality glasses. Previous research showed that in-car phone conversations can be distracting, but that the distraction might be reduced if the remote caller receives visual information about the driving context. However, what happens if such video sharing becomes bidirectional? The recent introduction of commercial augmented-reality glasses in particular might allow drivers to engage in video-supported conversations while driving. We investigate how distracting such video-based conversations are in an experiment. Our participants operated a simulated vehicle, while also playing a conversational game (Taboo) with a remote conversant. The driver either only heard the remote conversant (speech-only condition), or was also able to see the remote person in a virtual window that was presented through augmented reality (video call condition). Results show that our participants did not spend time looking at the video of the remote conversant. We hypothesize that this was due to the fact that in our experiment participants had to turn their head to get a full view of the virtual window. Our results imply that we need further studies on the effects of augmented reality on the visual attention of the driver, before the technology is used on the road.

Abstract Autonomous buses are expected to become a cornerstone of future mobility systems. Especially during their introduction, passengers may require reassurance about the vehicle’s awareness of the situation on the road and of its intended next actions to further acceptance. In order to investigate the need and requirements for information about the vehicle’s awareness and intent from the perspective of first-time users, we conducted two user studies in a state-of-the-art autonomous bus at public demonstration spaces. In the first study, participants underwent a demonstration ride with the bus and were then asked about their needs for awareness and intent communication. The second study took participants on a ‘simulated ride’ within a stationary bus, in which typical scenarios of the road ahead were presented, together with different awareness and intent cues. Our results suggest that, first, future autonomous bus passengers may be in need of such awareness and intent communication screens. Second, we found that awareness and intent communication may be of greater importance for the indication of potential hazard recognition than for indicating route directions. Third, due to their complementary strengths, none of the three compared types of visual communication (text, icon and augmented reality) should be used in isolation.

Integrated avionics architectures offer advantages such as higher flexibility, reliability, simplicity, future upgradeability and weight saving over previous federated designs. Successful implementations of integrated modular avionics (IMA) are onboard Boeing B777, B787, Airbus A380 and A350. These applications often result in development and maintenance cost not suitable for regional and general aviation aircraft. One popular approach to overcome this problem is by using integrated flight deck (IFD) supplied by avionics manufacturers such as Garmin or Honeywell. These manufacturers often optimize IFDs for applications in developed countries. For example, with the development and widespread use of satellite-based global positioning system (GPS) in the US, Canada and Europe, some terrestrial navigation equipment (e.g. ADF and DME) are no longer included in the standard IFD packages offered for commercial aviation. However, many areas in the rest of the world still use and rely largely on the availability of the ADF, DME, etc. Aircraft flying in these areas need to comply with the local requirements for terrestrial navigation systems already deployed. In this paper a study on the implementation of additional avionics equipment on Garmin G1000 for advanced regional turboprop aircraft is presented. G1000 is an integrated avionics system that integrates many electronic components including navigation, communication, course, attitude, display, etc. It has been widely used in all kinds of civil aviation aircraft. In order to conform to local and modern requirements, ADF receiver, DME transceiver, traffic alerting system and weather radar need to be integrated. Preliminary reliability analysis using fault tree method is performed for the designs to ascertain their safety as set out in the requirements for advanced regional turboprop aircraft.
