Next Generation Radar (NGR) concept achieves high sensitivity, better accuracy, and good transportability, while the distributed aperture coherence-synthesizing radar is an important direction, which coherently combining multiple close distributed radar apertures. Some basic study on this new-type radar is performed with several experiment results.
According to the calibration of binocular vision, an improved two-stages camera calibration method involved with multi-distortion coefficients is introduced in this paper. It takes the sum of distance in the world coordinate between ground truth 3D points and calculated 3D points as cost function. The 3D points' coordinate are calculated by the imitated direct linear transformation (IDLT) triangulation...
Outliers (false matches) detection techniques are very important for computer stereo vision. There always exist some outliers in spare matching and dense matching which impact the following 3D reconstruction in effect and accuracy. The author discussed some detection algorithms for outliers on the basis of 2D space and 3D space, and put forward a grey pre-processing algorithm applying beforehand to...
