The advent of photogrammetry using unmanned aerial vehicles (UAVs) has proved a cost effective and efficient alternative to traditional remote sensing techniques and Lidar. Considering lower cost and better flexibility, in this paper we conducted a survey and acquired high definition topographic data involving a mini consumer grade UAV. We aim to assess the accuracy of a mini consumer grade UAV production...
We present a new hybrid reality system that supports the monitoring and visualizing of a welding system. Our system first uses 3D scanning techniques to create a digital model of objects to be welded. Based on the model, a mock-up is constructed from a set of templates or 3D printed. The welding process is captured by cameras and visualized on the 3D mock-up using projectors. The welder can therefore...
Many hardware designs have been developed to allow a camera to be placed optically directly behind the screen. The purpose of such setups is to enable two-way video teleconferencing that maintains eye-contact. However, the image from the see-through camera usually exhibits a number of imaging artifacts such as low signal to noise ratio, incorrect color balance, and lost of details. We develop a novel...
