This paper realizes a 3D reconstruction system with Kinect, which can rebuild high-level, geometrically accurate 3D models in real-time with texture feature. Now the data formats, such as .obj, .stl, .ply etc are supported in the system, which can be directly applied in Maya, CAD and other 3D animation modeling software. The implementation of the system in our paper only requires a low-cost Kinect,...
It is challenging to quantitate micron-scale defects on the surface of large optics. Based on microscopic scattering dark-field imaging, sub-aperture scanning and stitching, the Surface Defects Evaluating System (SDES) can spot and measure scratch and digs on large optics. In order to evaluate defects of down to sub-micron over apertures of hundreds of millimeters, high magnification zoom microscope...
A new image based activity recognition method for a person wearing a video camera below the neck is presented in this paper. The wearable device is used to capture video data in front of the wearer. Although the wearer never appears in the video, his or her physical activity is analyzed and recognized using the recorded scene changes resulting from the motion of the wearer. Correspondence features...
In this paper, a stereo correspondence algorithm based on ground control points (GCPs) is presented. First of all, a new scheme for determining GCPs is introduced, where the Hausorff distance is improved to find out the most possible and robust matches. With additional space information provided by the Hausdorff distance, the algorithm effectively eliminates outliers and mismatches of control points...
