Triangulation free 3D Reconstruction from LiDAR Data

2010-06-01
We demonstrate a generic method for visualization of high-resolution unorganized and noisy 3D data points with a surface of significantly lower resolution. To this effect, we feed our algorithm with all the go Light Detection And Ranging (LiDAR) data and approximate it with a triangular mesh that is being deformed iteratively until convergence. Our main contribution is avoiding the direct triangulation of LiDAR points, a cumbersome step common in literature.

Multimodal Stereo Vision Using Mutual Information with Adaptive Windowing
Yaman, Mustafa; Kalkan, Sinan (2013-05-23)
This paper proposes a method for computing disparity maps from a multimodal stereovision system composed of an infrared and a visible camera pair. The method uses mutual information (MI) as the basic similarity measure where a segmentation-based adaptive windowing mechanism is proposed for greatly enhancing the results. On several datasets, we show that (i) our proposal improves the quality of existing MI formulation, and (ii) our method can provide depth comparable to the quality of Kinect depth data.
Retraction Free Motion Approach and Its Application in Automated Robotic Edge Finishing and Inspection Processes
Nemer, Mahmoud; Konukseven, Erhan İlhan (null; 2016-12-15)
In this paper, a motion generation algorithm for a six Degrees of Freedom (DoF) robotic hand in a static environment is presented. The purpose of developing this method is to be used in the path generation of the end-effector for edge finishing and inspection processes by utilizing the CAD model of the considered workpiece. Nonetheless, the proposed algorithm may be extended to be applicable for other similar manufacturing processes. A software package programmed in the application programming interface (AP...
Stratified calibration and group synchronized focal length estimation for structure from motion algorithms
Çalışkan, Akın; Alatan, Abdullah Aydın; Department of Electrical and Electronics Engineering (2017)
The estimation of unknown calibration parameters of the cameras without using any calibration pattern is critical for the performance of the 3D computer vision applications such as structure from motion, pose estimation, visual odometry, and it is still an open problem for the researchers. In this thesis, our contribution is two folded. First of all, we propose a novel stratified approach for estimating both the focal length and the radial distortion of a camera from given 2D point correspondences without k...
Multi-baseline stereo correction for silhouette-based 3D model reconstruction from multiple images
Mulayim, AY; Atalay, Mehmet Volkan (2001-01-25)
Silhouette based reconstruction algorithm is simple and robust for 3D volume estimation of an object. However? it has two main drawbacks: insufficient number of viewing positions and the inability to detect concavity regions. Starting from an initial convex hull of the object to be modeled which is generated by a silhouette based reconstruction, an algorithm based on photoconsistency is described. The algorithm basically carves the excess volume elements using the multi-baseline stereo information. Result o...
Wavelet domain image resolution enhancement using cycle spinning and edge modelling
Temizel, Alptekin (2005-09-08)
In this paper we present a wavelet domain image resolution en-hancement algorithm. An initial high-resolution approximation to the original image is obtained by means of zero-padding in the wavelet domain. This is further processed using the cycle-spinning methodology which reduces ringing. A critical element of the algo-rithm is the adoption of a simplified edge profile suitable for the description of edge degradations such as blurring due to loss of resolution. Linear regression using a minimal training s...
