We introduce the collaborative telepresence workspaces for SPACE operation and science that are under development in the European research project CROSS DRIVE. The vision is to give space mission controllers and scientists the impression of “beaming” to the surface of Mars, along with simulations of the environment and equipment, to step out together where a robot has or may move. We briefly overview...
In this paper we examine how closely together images to be used in 3D reconstruction are captured, when acquisition is started using a software-based trigger delivered to multiple computers on a network. In addition we compare a software triggered pull system to a push system. Synchronisation is a key component in 3D reconstruction systems and can also be one of the most problematic. In a shape-from-silhouette...
We present an analysis of the requirement for input synchronisation in a multi-camera 3D reconstruction system for real-time applications such as telepresence. Synchronisation of the cameras at the acquisition stage is universally used to ensure the images feeding the reconstruction algorithm were taken at the same time. However, this requirement adds delays to the reconstruction pipeline, therefore...
