Task Result Analysis¶
For task execution results, the platform provides multi-dimensional comprehensive analysis: it supports visualization analysis of task execution processes and results, intuitively reproducing the full workflow of a task run. It also allows convenient viewing of multiple result file types, including CSV trajectory data and test reports, helping users conduct a thorough review and analysis of task results from process, data, and conclusion perspectives.
1. Task Visualization Analysis¶
1.1 Trigger Visualization¶
For running tasks, click the Video Monitoring icon to open the task run visualization interface.
For completed tasks, click the Use Case Replay icon to open the task result visualization interface.
1.2 Visualization Interface¶
Warning
Visualization analysis supports two modes: High-Fidelity Rendering and Simplified Rendering. Switch between modes in Global Settings — Visualization Tool.
Team Edition — Cloud does not currently support High-Fidelity Rendering visualization.

| 19 | Real-Time Parameter Panel Toggle | Includes Sensors, V2X, and Perception tabs. |
| 20 | Data Filter | Click to open a filter dialog where users select the data types displayed below. |
| 21 | Information Display | Switch content using the Tab menu at the top. Sensors shows Ego Vehicle sensor dynamics parameters over time. V2X shows various event information. Perception shows the Ego Vehicle's perception and decision-making information. |
| 22 | Test Log List | Displays test log information during the test, including INFO, WARN, and ERROR levels. |
1.2.2 Simplified Rendering¶
| ID | Item | Description |
