Racing Analyze GUI

MATLAB · Multi-log telemetry analysis · Replay · Segment metrics

Racing Analyze GUI is a segment-based telemetry workbench for loading multiple runs, comparing the same track region across runs, replaying them in time, and extracting metrics for coaching-oriented review.

What I Built

  • Track-core and segment workflow so repeated runs can be compared against the same reference structure.
  • Multi-log loading and caching for quick switching after one analysis pass.
  • Synchronized replay system with time slider, play/pause/stop, speed control, and pane-aware markers.
  • Flexible pane system with XY, TS, MAP, POLAR, KDE, and GG views plus per-pane rerender/pop-out tools.
  • Channel-flexible visualization where arbitrary logged channels can be assigned to axes or color.
  • Metrics extraction for segment time, speed statistics, and acceleration-related indicators.

Metrics Exposed In The App

  • segTime: selected-segment time
  • vmin / vmean / vmax: speed min / mean / max
  • vin / vout: speed at segment entry / exit
  • arms / a95 / amax: acceleration magnitude statistics for quick comparison

Result

  • Built a reusable telemetry inspection workflow around track segments, replay, and multi-run comparison.
  • Implemented pane state, replay control, flexible channel mapping, and segment metrics as UI features.
  • Connected the analysis workflow to the same racing telemetry data collection path.

Evidence

  • The GUI is structured as a workbench: track build, run caching, segment slicing, replay, plots, and metrics are separate steps in one flow.
  • The app supports multiple analysis views and pane-level tools, which is stronger evidence of repeated real use than a single static screenshot.
  • The telemetry workflow is connected upstream to the Racing Telemetry Stack, so this page describes the analysis side of the same system.

Validation Scope

  • This page focuses on implemented UI behavior, replay workflow, and exposed segment metrics.
  • The strongest evidence is the reusable analysis workflow: track build, multi-run loading, synchronized replay, flexible plots, and metrics extraction.
