Photogrammetry & Computer Vision - Gaussian splat-GIS & Remote sensing
With 5 years of hands-on experience, I build robust gaussian spalting 3d models, photogrammetry and computer vision pipelines backed by solid academic work (MSc; current PhD in photogrammetry, CV, and GIS). Services ✔ Photogrammetry & 3D Reconstruction • Camera calibration/alignment & bundle adjustment • SfM/MVS → dense point clouds, meshes, textured models, orthophotos • GCP/scale integration • Accuracy & QA reports ✔ NeRF & Gaussian Splatting • Training, evaluation & export with NerfStudio and PostShot (CLI) • High-fidelity reconstructions • .ply → .splat conversion • Automated, repeatable runs ✔ Computer Vision for Infrastructure • Object detection/segmentation (solar panels, power lines, poles, buildings) • RGB + thermal fusion for anomaly/defect detection • Change tracking across missions • Dataset curation & labeling workflows ✔ UAV / LiDAR / Point-Cloud Processing • DEM/DSM/DTM, contours, surface generation • Ground/object classification • Orthophoto & volume calculations • Multispectral analysis • Solar-panel & power-line inspection ✔ Satellite Imagery (supporting) • NDVI & vegetation indices • Multispectral processing • ML-based classification • Change detection ✔ Automation & Batch Pipelines • Headless/CLI workflows, GPU acceleration • End-to-end scripting, logging, packaging deliverables Tooling & Stack COLMAP (API) • RealityCapture (CLI) • Agisoft Metashape (Python API) NerfStudio, PostShot (CLI) for NeRF & Gaussian Splatting CloudCompare (CLI), PDAL, GDAL, OpenCV, PyTorch Python / C++ / .NET / MATLAB (as needed) Open to “out-of-the-box” problem solving across surveying, geospatial tech, and 3D vision.
