Select-and-Combine (SAC): A Novel Multi-Stereo Depth Fusion Algorithm for Point Cloud Generation via Efficient Local Markov Netlets

no code implementations23 Aug 2023 Mostafa Elhashash, Rongjun Qin

However, the noises and outliers caused by stereo matching and the heterogenous geometric errors of the poses present a challenge for existing fusion algorithms, since they mostly assume Gaussian errors and predict fused results based on data from local spatial neighborhoods, which may inherit uncertainties from multiple depths resulting in lowered accuracy.

A Review of Mobile Mapping Systems: From Sensors to Applications

no code implementations31 May 2022 Mostafa Elhashash, Hessah Albanwan, Rongjun Qin

The evolution of mobile mapping systems (MMSs) has gained more attention in the past few decades.

Constrained Bundle Adjustment for Structure From Motion Using Uncalibrated Multi-Camera Systems

no code implementations8 Apr 2022 Debao Huang, Mostafa Elhashash, Rongjun Qin

We performed our bundle adjustment using the proposed constraint and then produced 3D dense point clouds.

Investigating Spherical Epipolar Rectification for Multi-View Stereo 3D Reconstruction

no code implementations8 Apr 2022 Mostafa Elhashash, Rongjun Qin

However, existing approaches face challenges in applying dense matching for images with different viewpoints primarily due to large differences in object scale.
