The three-dimensional visual positioning of aviation engine rotor bolts is great significance for automatic connection status detection. However, the internal space narrow, and shooting angle limited. Existing vision-based methods based on vertical are insufficient to meet bolt requirements. In this paper, a robust method at arbitrary angles proposed. First, deep learning-based object detection employed extract from both color image depth image. Then, an arc-support line segments (ASLS)...
Fingerprint sensor (FPS) becomes rapidly popular due to small size and high safety. The molding thickness of capacitive FPS will affect its performance needs be accurately measured controlled. Different from cutting laser drilling method, one none destructive method with Terahertz electromagnetic wave is introduced. can penetrate into the package materials. through time delay two pulse waves. correlated microscope view result within ±4um gap.
With the increasing demand for automated detection of bolt connection parameters in industrial field, there is an urgent need position information bolts to guide operation equipment. Therefore, this paper proposes a visual positioning method that combines depth maps and color images. Firstly, outlier points are eliminated from map using histogram analysis. The bottom projected onto two-dimensional plane through slicing, coarse achieved Density-Based Spatial Clustering Applications with Noise...
Abstract HBDY is a sandstone reservoir, which vertically multi-layered, severe heterogeneous, and developed with water flowing channels. The injecting-production well patterns are imperfect. It has high recovery degree, 36.2%, cut, 83.9%. average reservoir crude oil viscosity 6.3 mPa.s. temperature 90°C, the formation salinity 10701mg/L. A new particle-type polymer slug combined linked gel (LPG) pre-set was applied during May, 2014 to Feb., 2016, technical economic success obtained....
Yttrium calcium oxoborate (YCOB) and Nd:YCOB crystals of high optical quality large dimension have been grown by the Czochralski method. Measurements refractive indices confirmed that these were negative biaxial. The absorption spectra determined various spectrum parameters calculated. Polarized revealed strong anisotropic character Nd:YCOB. Raman indicate nonlinearity crystal is mainly attributed to planar BO3 triangles in structure rather than a distortion oxygen octahedra.
