Research on Multi-dimensional Dynamic Data Fusion and Real-time Calculation Method for Intelligent Monitoring of Safety Belts in Power Grid Construction Environment
Bibliographic record
Abstract
This paper proposes a real-time computational method for multidimensional dynamic data fusion (VIO-SLAM) for intelligent monitoring of seat belts in the grid construction environment.In this paper, the optical flow method is first used to process and track point features, and the geometrically constrained line matching algorithm is utilized to improve the accuracy of feature matching.Combined with IMU modeling and pre-integration techniques, it effectively reduces the computation of highfrequency IMU data and improves the system efficiency.At the same time, a real-time lightweight semantic segmentation system is constructed to achieve fast semantic understanding of the construction scene.The real-time and accuracy of data processing is further improved by sliding window method with BA optimization.On this basis, a VIO-SLAM algorithm based on EKF fusion of multidimensional dynamic data is proposed to realize real-time monitoring and localization of seat belt status.The results show that when a dangerous collision occurs in a complex power grid construction environment, the protection performance of shoulder belt, neck bending moment force and head acceleration of the construction personnel under the method of this paper is much higher than that of the traditional seat belt.In the process of emergency collision avoidance, the VIO-SLAM algorithm is able to tighten the seat belt in advance for the construction personnel, which has better protection performance and can achieve the purpose of "collision avoidance and damage reduction".The pre-tensioning force for eliminating the gap in the webbing of seat belts and the pre-tensioning force for somatosensory warning reminders are also determined to improve the protection performance of construction workers.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
