This paper presents an improved modelling method for a water jet‐based multi‐propeller propulsion system. In our previous work, the modelling experiments were only carried out in 2D planes, whose experimental results had poor agreement when we wanted to control the propulsive forces in 3D space directly. This research extends the 2D modelling described in the authors’ previo...

3D models of indoor environments are important in many applications, but they usually exist only for newly constructed buildings. Automated approaches to modelling indoor environments from imagery and/or point clouds can make the process easier, faster and cheaper. We present an approach to 3D indoor modelling based on a shape grammar. We demonstrate that interior spaces can be modelled by iter...

In order to perform object modelling by image processing procedures, line or feature extraction and stereo matching used to perform. However, there are some issues for efficient 3D modelling of objects. In particular, efficient line matching for reconstruction of objects is needed to be resolved. With this objective, a robust line matching method which includes optical flow and trifocal tensor ...

In order to perform object modelling by using images processing procedures, line or feature extraction and stereo matching will be performed in general. However, there are some issues of efficient 3D modelling for historical structure. In particular, efficient line matching for reconstruction of objects is needed to be resolved. With this objective, this paper investigates a robust line matchin...

In the last years, cardiovascular diagnosis, surgical planning and intervention have taken advantages from 3D modelling and rapid prototyping techniques. The starting data for the whole process is represented by medical imagery, in particular, but not exclusively, computed tomography (CT) or multi-slice CT (MCT) and magnetic resonance imaging (MRI). On the medical imagery, regions of interest, ...

In this paper a new method of modelling and dynamic composition of behaviour-rich interactive 3D virtual museum exhibitions is described. The method enables museum experts, without advanced knowledge in computer programming, to create 3D virtual exhibitions accessible both locally inside the museums and remotely over the Internet. The method uses a novel Beh-VR modelling approach, which is comp...
