Automated Ground Control Point Identification using Deep Learning Techniques

VGC 2023 - Unveiling the dynamic Earth with digital methods : 5th Virtual Geoscience Conference ; Book of Abstracts, 2023
Ground Control Points (GCPs) play a crucial role in photogrammetry, providing essential information for georeferencing, registration and scaling of aerial and satellite imagery. These reference points, with known coordinates, are strategically placed and precisely measured on the ground to achieve accurate georeferencing in the photogrammetric process.

Learning to Detect Ground Control Points for Improving the Accuracy of Stereo Matching [PDF]

2014 IEEE Conference on Computer Vision and Pattern Recognition, 2014
While machine learning has been instrumental to the ongoing progress in most areas of computer vision, it has not been applied to the problem of stereo matching with similar frequency or success. We present a supervised learning approach for predicting the correctness of stereo matches based on a random forest and a set of features that capture various
