Abstract

fetched live from OpenAlex

In this thesis, a framework based on open-source hardware is proposed and built to study the practicability of its use in indoor robotics research.Two Raspberry Pi camera modules are used as a range sensor for indoor robot triangulation in a static scene, which infers 3D information from 2D space using stereo vision.The local Block Matching method and Semi-Global matching method are implemented in dense disparity map estimations.3D reconstructions are performed and binary 2D maps are generated.Previous work has paid attention to iterative methods to minimize the global energy function in solving matching problems.This thesis presents two vectorized methods that are suitable in stereo vision triangulation and acceptable for use in robotic applications.Results show that the depth estimation of both methods can be accurate to centimeters in between half a meter to four meters of range.Real-time implementation of these approaches has not been investigated.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
