Simulation data recording tool
The EIF test data recording tool is a core component in Mega Toolbox for remote development. It records the original on-site camera image stream and IMU sensor data to generate simulation files that can be replayed in the Unity Editor.

Recorded file name
Note
Recording range: limit it to the earlier map acquisition area, with emphasis on covering recognition effect verification points. Viewing angle requirement: simulate the user's viewpoint. Avoid large sudden turns and long periods facing textureless areas. Duration limit: each recording segment must be less than 10 minutes. End operation: after recording is complete, tap the stop button at the bottom.
