In modern automated systems the usage of sensors with orthogonal measurement principles is indispensable for assuring a redundant system. The combination of laser scanners and cameras is particularly prevalent. To profit from the potential of fusing information from these sensors, the basic step is sensor registration. State of the art cross-calibration methods for laser scanners and cameras establish...
This paper gives an insight in the preliminary results of an ongoing work about heterogeneous point feature estimation acquired from different type of sensors including structured light camera, stereo camera and a custom 3D laser range finder. The main goal of the paper is to compare the performance of the different type of local descriptors for indoor office environment. Several type of 3D features...
Seam measuring of complex tight butt joint without misalignment for laser welding is a challenging problem. The allowable seam gap width and misalignment in laser welding process are less than 0.1 mm for thin sheet around 2 mm thickness. Current measuring methods or sensors can not stably and accurately extract 3D seam position and seam gap width, due to narrow seam gap and too little misalignment...
Dimensional analysis from a single image is an interesting topic of investigation in the research community, even though range sensors are becoming a common alternative for the generation of metric information in real-time. The interest in obtaining metric measurements from a single image is motivated by a wide spectrum of applications such as cultural heritage, civil engineering, urban planning,...
