Smart IoT devices, such as lights, locks, washing machines, security cameras, etc., are becoming omnipresent in households and companies across all industries. However, most of these devices communicate over non-secure local protocols or via cloud services where security policies are not transparent. Vulnerabilities may lead to unauthorized access...

Industry 4.0 comprises a wide spectrum of developmental processes within the management of manufacturing and chain production. Presently, there is a huge effort to automate manufacturing and have automatic control of the production. This intention leads to the increased need for high-quality methods for digitization and object reconstruction, espec...

The presented paper describes the creation of a mobile application module for showing a current menu at Mendel University cafeterias. Nowadays, the students and the university staff have the menu accessible through a static webpage. The presented solution serves as a dynamic presentation of the current menu for all Mendel University in Brno cafeter...

Small Island Developing States (SIDS) are now experiencing the local consequences of a changing climate, environment, and society. Nonetheless, climate change research frequently remains at regional or national levels. Without locally grounded data, islanders’ perceived impacts of the changes might not be considered, thereby causing difficulties wh...

There are many different types of places in any city. These places include playgrounds, dog runs, cultural heritage sites and many more. A city usually wants to provide information about location and equipment of these places. The common way is via a city website. However, nowadays a much more common source of information are mobile applications. T...

Optimization of road networks is a common concern worldwide, primarily for safety purposes. Because the extent of these networks is substantial, automation of their inventory is highly desirable. This paper concentrates on the road inventory process that is necessary for regular maintenance. The key part of our road marking detection and reconstruc...

There are numerous situations when it is utmost important to share efficiently some spatial data among a group of people. Floods can be taken as an obvious example. Many stakeholders including mayor or rescue service workers must have actual information about the conditions in the terrain. And most importantly, all of these can contribute to the in...

Almost any university in the world has a map showing places around their campus. This map can have many different forms, from paper one through a map on a mobile device. Usually, these maps show important places on campus, such as buildings. However, these maps often do not cover places outside of the campus. The goal of this article is to identify...

This paper presents novel approach for detection of pole-like objects from LIDAR data. The designed method uses directional vector to detect pole-like structures in unordered point clouds. A new segmentation algorithm is presented as well. The segmentation is designed to overcome a common problem found in LIDAR data of urban environments, where a l...

This book brings together the work of researchers in Eastern and Western Europe, who analyze competitiveness, social exclusion and sustainability from a range of perspectives. It examines the key challenges faced by the EU in its efforts to establish a socially inclusive and greener path to growth and develops policy recommendations to simultaneous...

There is a general understanding that spatial data are essential for many different analyses—from purely environmental examples such as weather modelling to cost analysis calculations for logistics. All developed countries have created national agencies that are focused on spatial data collection and maintenance. A well-known example is the USGS (U...

Road inventory is very important for effective transportation management. This process is usually done by a technician in the field, manually from obtained aerial/satellite images or semi-automatically by a software application. The first two options are very time consuming, hence expensive. Many companies therefore try to process at least part of...

Present time is characterized by limited availability of resources. Not only organizations are limited by amounts of nonrenewable natural resources, but also by amounts of renewable resources like human, financial and time resources. Today issue with resources is raising demand for them. It is this rising demand that leads to optimization of handli...

Gestures are a common way of interaction with mobile devices. They emerged especially with the iPhone production. Gestures in currently used devices are usually based on the original gestures presented by Apple in its iOS (iPhone Operating System). Therefore, there is a wide agreement on the mobile gesture design. In last years, it is possible to s...

High population as well as the economical tension emphasises the necessity of effective city management – from land use planning to urban green maintenance. The management effectiveness is based on precise knowledge of the city environment. Point clouds generated by mobile and terrestrial laser scanners provide precise data about objects in the sca...

One of the key features of virtually all object recognition systems is the ability do deal with occlusions of detected objects. This article is focused on identification of occluded artificial objects such as square markers. The article reviews frequently used methods for detection of partially occluded markers. Further, our implementation of two o...

Physical model is a common tool for testing of the product features during the design process. This model is usually made of clay or plastic because of the modifiability of these materials. Therefore, the designer could easily adjust the model shape to enhance the look or ergonomics of the product. Nowadays, some companies use augmented reality to...

Augmented reality is a visualization technique widely used in many applications including different design tools. These tools are frequently based on tracking artificial objects such as square markers. The markers allow users to add a 3D model into the scene and adjust its position and orientation. Nevertheless, there are significant problems with...

The first part of the article describes our approach for solution of this problem by means of Augmented Reality. The merging of the real world model and digital objects allows streamline the work with the model and speed up the whole production phase significantly. The main advantage of augmented reality is the possibility of direct manipulation wi...
